Company Principles – breathing life into buildings!

Founders and directors Nigel and Joyce Gervis

T y-Mawr ˆ being presented with the LABC All Wales Award as winner of the “Technical Innovation of the Year, 2013”

Established in 1995, by husband and wife - Nigel and Joyce Gervis, Ty-Mawr ˆ Lime Ltd has made an enormous contribution to resurrecting the use of traditional building materials and has become a market leader in the design, manufacture and distribution of environmentally-friendly building materials and systems providing a ‘one-stop’ shop for clients throughout the UK.

Nigel, Joyce, Henry, Harvey and Cai on visit to India, 2013

They have received several awards for their work in this field and at the end of 2009, were named as one of the 52 ‘sustainability champions’ on Wales’ first Green List! for their contribution to sustainability in Wales and in 2012, Nigel Gervis, Technical Director, received the Marsh Award for Trainer of the Year (Traditional Building Skills) supported

by CITB, Construction Skills and English Heritage.

Their approach to buildings and building products is based on the following principles that are still central to the whole business, namely:

caring for buildings

Caring appropriately for buildings requires an understanding of how they are constructed and hence how they function – only then is it possible to identify the right materials to repair them with.

We understand the technical qualities of each of our products, this enables us to give the best possible advice and support for each project.

Careful product selection is vital to ensure the health and longevity of your building.

caring for the environment

All of our products are designed, assessed and selected to have minimal environmental impact.

We continually work to monitor and improve the environmental credentials of all of our products e.g. we have developed plasters that use recycled glass as an aggregate (instead of extracting virgin sand) or hemp fibres which are fully renewable.

We were the first company in Wales to gain our BS8555 Environment Management System Award under the UKAS Accredited Seren Scheme.

It demonstrates our commitment to the environment - from the paper we choose, to the way in which we dispose of any waste. It runs through every aspect of our business, we are not merely producing and selling these products because it is fashionable, it is absolutely core to our business and always has been e.g. our head office and training centre no longer run on oil, they are heated through a heat recovery system installed on the manufacturing yard, backed up by a biomass boiler - this reduces our emissions by some 40 tonnes of carbon dioxide per annum!

up to 90% of our time indoors, so the quality of the internal environment is important to our well being.

Our materials do not contribute to indoor pollution; in fact some of them actually help to improve indoor air quality e.g. T y-Mawr ˆ THERMAFLEECE® sheep’s wool insulation actually locks in formaldehyde given off by heavily glued products and our plasters, paints and boards help to regulate humidity, this is key to maintaining appropriate comfort levels in the room.

sustainability

We want to contribute to a sustainable future – we believe that one important aspect of this is through supporting local communities – we strive to buy and promote local and British products. Where this is not possible, we work to find the product with the best ecological and technical credentials and hope that in generating a market, a local product may eventually be produced. This has happened with several of our products, most notably our sheep’s wool insulation which is now made from Welsh wool, as well as reducing product road miles, this will contribute in a small way to sustaining the rural communities in which we live and work.

people

quality

We are committed to developing a skilled and experienced workforce in stable and interesting jobs, this we believe ensures exceptional service for our clients and makes a huge contribution to sustaining our rural communities in which our staff are all based.

We are part of and invest in the Welsh Government’s Workforce Development programme, identifying training needs within our business and providing opportunities for development.

caring for health

Finally, we are excited about combining new and traditional materials in innovative ways. As a result, we have developed some award winning products: the insulated limecrete and sublime® flooring systems (pages 24-27) and the glaster® plaster (pages 18-19) and hemp lime plaster (pages 13-15) ranges.

We have been determined to maintain the quality of our products and services as the business has grown.

In 2007, we gained our ISO9001 quality management system award helping to ensure that we continue to deliver the best possible products and services through approved procedures.

Lime Products Introduction & Benefits Parthenon built in 432BC

Benefits of Lime - caring for buildings Lime has been used as the binder in mortars, plasters, paints and floors for centuries, it is usually blended with an aggregate to make mortar or an aggregate and fibre to make plaster/render.

Lime has a proven track record, it has been used in architecture since 12,000 B.C. and there are plenty of examples from antiquity that still survive today (how many modern buildings will be standing in the next hundred or even thousand years, like the Parthenon built in 432BC).

We were cement-free in the UK up until the 1920s, so buildings pre-dating this would primarily have been constructed using lime. It is staggering to think that all of the stone and brick buildings that we see around us every day like Victorian terraces, Georgian streets, farmhouses, churches, chapels, barns, village halls, castles, cathedrals, stately homes and abbeys are all built without cement - and those that have been repaired and cared for appropriately with lime are still standing.

It is often thought that lime is not as ‘strong’ as cement and so has no place in buildings today, but lime has other qualities, qualities that have helped traditional buildings to survive (very sustainable having buildings that last for centuries!) and qualities that are now encouraging a new generation of builders/developers to incorporate lime into their new builds - creating healthier, more sustainable homes. > l ime products are vapour permeable - this is important in solid wall buildings as it means that any moisture is allowed to escape from the walls. This helps to control condensation and damp within the building (most modern renders, plasters, mortars and paints are impervious, trapping moisture in the walls, leading to problems such as condensation, mould growth and even degradation of the fabric of the building such as timbers rotting, bricks/ masonry crumbling). > l ime mortars are relatively flexible and will accommodate some movement in a wall without cracking, each joint of lime mortar is like a mini expansion joint. If lime cracks it can ‘self-heal’ when exposed to air unlike its modern counterparts which are harder and hence more brittle.

This allows movement and flex within structures whilst allowing them to remain upright! (just look up at the beautiful domed ceiling in a great cathedral, only achievable because of this quality!) Often in earth quake zones, the ‘traditional’ buildings constructed of lime remain standing whilst modern ‘cement’ buildings fall down as they are more brittle. > l ime mortars are sacrificial - so any salt or frost damage occurs in the mortar not in the more expensive components like brick/masonry.

Lime Products Lime allows bricks to be reclaimed ready to be re-used, cement is so strong that this is not often possible!.

Impervious, hard cement render has been removed revealing rotten lintels and degrading masonry caused by trapped moisture.

Caring for the environment

Caring for health

We, as well as others, have been keen over the last few years to highlight the potential of lime within new builds as a cement replacement.

The use of cement has grown enormously, by 2020, world production is expected to top 3,500 million tonnes, three times the level used just a decade ago. 10% of worldwide Carbon Dioxide emissions are attributed to the production of cement (this is comparable with the aviation industry). The cement industry itself has taken measures to reduce the impact but there are things we can all do like considering alternatives whenever we think about using it in our buildings/structures. The range of limes now available as well as the work we have been doing in developing ‘systems’ has made the possibility of this much greater. See new timber-framed buildings (page 30), upgrading ‘solid wall’ constructions (pages 33-35), warm roofs (page 32) and limecrete floors (pages 24-27).

lime plasters and limewash are nontoxic, therefore they do not contribute to indoor air pollution unlike some modern paints.

Finally, lime products create a beautiful, lively, unique aesthetic that no modern material can replicate....well we think so...

The Lime Cycle Water-born Carbon Dioxide (CO2) is absorbed over time to form Calcium Carbonate (CaCO3)

Burning limestone in a kiln drives off Carbon Dioxide (CO2) and water (H2O)

Slaked lime (putty) is mixed with selected sands to produce mortars and plasters, or with water to produce limewash

> lime

enables other natural and sustainable products such as wood (including woodfibre, wood wool boards), hemp, straw etc to be used because of its ability to control moisture (if cement was used, these buildings would compost!).

lime plaster is hygroscopic (literally means ‘water seeking’) which draws the moisture from the internal to the external environment, this helps to regulate humidity creating a more comfortable living environment as well as helping to control condensation and mould growth which have been shown to have links to allergies and asthmas.

BU

> l ime mortars allow other building components such as stone, wood and bricks to be reused and recycled because they can be easily cleaned of mortar/ limewash.

n

CARB

> l ime is burnt at a lower temperature than cement and so has an immediate energy saving of 20% (although kilns etc are improving so figures do change).

A standard lime mortar has about 60-70% of the embodied energy of a cement mortar.

It is also considered to be more environmentally friendly because of its ability, through carbonation, to re-absorb its own weight in Carbon Dioxide (compensating for that given off during burning and so forms the well known lime cycle - see opposite).

Introduction & Benefits

Impervious modern paints prevent the wall from ‘breathing’ – it will blister, peel and flake and can lead to problems of condensation and mould growth.

Lime Products Types of Lime Courtesy: Sara Bennison

Types of Lime There are many types of lime on the market.

It is crucially important to understand their differences and the way in which they perform, only then is it possible to make an informed choice about which lime to use for different applications and environments.

Slaked/High Calcium/Putty/Air/‘Fat’ or Non-Hydraulic Lime (see page 7)

Courtesy: Singleton Birch

This lime is produced by slaking fresh Quicklime in an excess of water. It is also known as non-hydraulic lime because it requires exposure to air in order to carbonate and does not set under water. This lime is regarded as the most appropriate lime for old buildings where maximum permeability and flexibility is required.

Premixed ‘wet’ products are made from this lime putty with the addition of an aggregate and/or fibre.

Natural Hydraulic Lime (see page 8)

In more recent years, hydraulic ‘hydrated’ limes have been successfully produced from limestone containing clay and other impurities which gives it a faster initial set in more extreme conditions (including under water).

There are many types of hydraulic lime and they are categorised according to the following (NHL - Naturally Hydraulic Lime): where the number refers to the compressive strength of the mortar after 28 days (please note the selection of aggregate and mix ratio will also effect the final strength). >N HL2 – contains less than 12% clay which means it is slower to set; >N HL3.5 – contains 12%-18% clay which gives a slightly faster set; >N HL5 – has up to 25% clay content which means that a much faster set is achieved.

These limes have become increasingly popular over the last decade because of their comparative ‘ease of use’ and ‘strength’, compared to fat limes.

Tˆy-Mawr’s premixed ‘wet’ lime products that are ready to use!

Hydrated or ‘Bag’ Lime This is the lime generally available in builders merchants. It is a non-hydraulic lime produced by slaking Quicklime with a shortfall of water which results in a powder. It is generally considered to be an inferior product to the fat lime putty described above for a number of reasons but primarily because it starts to degrade from the moment it is made and can actually fully carbonate in the bag before use.

Widespread use of ‘bag’ lime has given ‘lime’ a poor name because of the instances where it simply has none of its original properties left by the time the end-user works with it, hence it fails, dusts etc. If ‘bag’ lime is the only option, then it should be purchased as fresh as possible and left to soak for two days in clean water. Although the resulting product is chemically the same as ‘fat’ lime putty, it is physically different, in particular it is less ‘sticky’.

Pozzolans (see page 28)

Pozzolans are ‘heated’ materials such as brickdust, Pulverised Fuel Ash (PFA), Calcined Clay, that contain silica, alumina and iron which become reactive towards alkalis including lime. They are frequently used to help to give a fat lime mortar a ‘faster’ set (essentially creating an ‘artificial’ hydraulic lime) and are therefore helpful in many situations to broaden the applications for fat limes. It is believed that many historic mortars were ‘fat’ or ‘nonhydraulic’ as they often contain these ‘heated materials’ which change the performance of the mortar. Today, hydraulic limes are more commonly used, sometimes wrongly, for increased set and strength. Please see below for some guidance on specifying and choosing the right lime.

Properties Understanding the properties of the various limes will help to ensure a successful result through appropriate specification, see below.

The above diagram shows the ‘trade offs’ that need to be considered when choosing a lime - the stronger the lime, the faster it sets but the compromise is ‘vapour permeability’ and ‘flexibility’

Therefore, if work can not be rescheduled to another time of the year consideration should be given to adding a pozzolan to a fat lime (e.g. PFA, GGBFS) to speed up the set or to using a hydraulic lime. Appropriate protection is vital.

Choosing a Lime It is important for the well being of the building that the most appropriate lime product is chosen. Every situation needs to be carefully assessed e.g. in terms of: >s oftness of the stone, brick etc – this should be a major factor in selection.

The mortar should always be ‘softer’ than the stone/brick.

Occasionally, the choice still seems to be based on the availability of skills, unfortunately, lack of experience means that often the stronger hydraulic limes or even cement are introduced into buildings where they have no place and will, in the long term, almost certainly contribute to damp problems and damage the very fabric of the building.

Application guides, supplied with all of our lime-based products, provide far more detailed information and set out some ‘golden rules’ for successful results.

Before beginning to use any lime product, it should be understood that lime is caustic and eyes and skin should be protected at all times.

We make our own lime putty - it is produced by ‘slaking’ a British quicklime in an excess of water. It is then allowed to mature.

This fat lime putty can then be used to make plaster/mortar by blending it with an appropriate aggregate (see page 9), or diluted to make a limewash (see page 60).

Benefits >> it is regarded as the most appropriate lime to use in the conservation of old buildings where it is important to maximise softness, vapour permeability and flexibility.

>> it keeps indefinitely and especially well in buckets when stored correctly. >> our dedicated warehouse facility, semiautomated batching and stock rotation ensures that our putty is produced and stored to the highest standard.

>> we produce our own putties in Wales, in our manufacturing facility that is under our ISO9001 quality management system using British quick lime.

Hydraulic Lime is produced from limestone containing clay and other impurities which enables it to set without exposure to air (unlike fat lime products). It therefore means that these limes can be used in harsher conditions e.g. they are ideal for use in foundations, limecrete floors (see pages 24-27), sea-defence walls, chimneys, parapets, copings, paving etc.

Hydraulic Limes are supplied as a powder to which water and sand must be added in the correct ratios – see page 9 for our recommended aggregates for use with lime.

At Ty-Mawr, ˆ we stock Singleton Birch (Secil), St. Astier and Hanson Hydraulic Lime - we feel that it is important to have a full range so that we can be as objective as possible with our advice - strength, colour and environmental implications are all considerations.

Lime Products Aggregates for Mortars, Plasters & Screeds To make a successful lime mortar or plaster, lime must be blended with an appropriate sand/aggregate.

It is important to choose a well-washed, well-graded sand which will aid workability and minimise shrinkage.

At Ty-Mawr, ˆ we have trialed and carefully selected an excellent range of appropriate aggregates in a wide range of colours and textures. This allows you to produce a mortar as close to the original as possible where required.

We carefully blend some aggregates to produce a perfect grading for lime mortars and plasters – see below – this saves time gauging different sands on-site as well as giving the plaster/mortar the best possible qualities in terms of aesthetics and ease of use to aid a successful job.

For those concerned about the level of impact caused by sand extraction, we offer a range of recycled aggregates better for the environment.

Lime Products Premixed Lime Putty Mortars Damage caused by cement pointing

Courtesy: St Paulinus Church, Llangors

Old and historic buildings will require pointing as the mortar gradually deteriorates over time.

Benefits of premixed mortar: >> gives a consistent, accurate mix hence removes the potential for mixing and gauging errors on-site.

By using lime mortar to re-point, it will ensure that the building continues to function as it was designed (see page 2).

>> minimises waste - enables you to ‘knock-up’ as much as you require in a day, anything left over can be reused, so nothing goes to waste.

A well re-pointed and well maintained wall will not need re-doing for another century or so!

>> helps to keep the site organised and clean.

Our premixed lime mortars are ready-to-use, wet mortars that simply require ‘knocking-up’ prior to use (in a drum or site mixer or by using a whisk bit on a drill and a bucket).

>> colour and texture variations can be accommodated making sure regional variations are maintained.

They are produced by blending our fat lime putty with specially selected British Standard aggregates in our semi-automated production facility to ensure consistency and quality.

>> high quality aggregate selection produces a very workable ‘fatty’ mix, minimising shrinkage.

Selecting a Mortar The whole of St Teilo’s 13th Century Church was reconstructed at the National Museum of Wales, St Fagan’s using only our fat lime mortar - just as it would have been originally.

tips We do not add cement to any of our products.

To speed up the set or to increase the strength, see page 28 for pozzolans or call for advice.

Note: a lime mortar is not a cement mortar with a shovel of hydrated lime in it!

10

It is important when re-pointing an old building to select an appropriate mortar.

Send us a sample of your mortar (the size of a golf ball) for matching purposes.

Consideration should be given to both the colour and texture of the original mortar (unless it is to be subsequently limewashed).

Consideration must then also be given to the strength and flexibility required for a successful, long term mortar (see pages 5-6) or call us for advice.

Pierhead, Cardiff Bay. Courtesy: www.randmwilliams.co.uk

Lime pla­sters were commonly used in most buildings as the internal finish from the humble cottage to grand cathedrals, it is only in recent times that we have started to strip plasters off to reveal the stone or brick work. However, lime plasters have several attributes, as well as helping to maintain the well being of the building (moisture control and flexibility), lime plaster also has a ‘soft’ aesthetic which gives older buildings a particular ‘feel’.

Their ability to control moisture also makes them a highly appropriate finish for use with other ecological materials such as straw, wood and earth, hence their increased use in new eco-builds.

It is produced by blending our fat lime putty with specially selected aggregates – coarse for roughcast and base coats, and fine for the top coats. This is done in our semi-automated production facility which ensures consistency and quality.

Our premixed lime plaster can be supplied haired (synthetic or natural) or unhaired so that hair/fibre (see page 28) can then be added on site. We also produce a ‘Strawbale Mix’ which is an economic premixed plaster.

Lime plasters also improve the quality of the internal environment as they help to regulate humidity by absorbing moisture thus creating a healthier environment.

T yˆ -Mawr premixed lime plaster is a ready-touse, wet plaster that simply requires ‘knockingup’ prior to use. For information on suitable substrates (see page 6).

Lime Products Lime Hemp Plaster Tˆy-Mawr’s Lime Hemp Plaster is a blend of lime (binder) and British hemp plant fibres/shiv and fine aggregate, to make a plaster which is suitable for old buildings as well as ecological new builds.

Why hemp fibre?

Benefits

> l ike all plants, the hemp plant absorbs carbon dioxide as it grows (which is good for the environment).

>> made from a natural, renewable plant fibre (instead of depleting a natural aggregate resource).

> i t is one of the faster growing biomasses, producing up to 25 tonnes of dry matter per hectare per year. > i t is a low input plant – it does not require vast amounts of water or pesticides and uses no herbicides to grow, uniquely it also enriches and hence improves the soil in which it grows. > i t is now grown in the UK enabling us to produce a fully British product. > i t is renewable and therefore does not deplete a finite, natural resource (like sand) and so is more sustainable.

Where? >m ost conventional backgrounds – stone, brick, block, our wood wool and woodfibre boards, reed mat, reed board and traditional battens/laths. > i nternally as a plaster which can be left as a textured finish or trowelled smooth (n.b. for a completely smooth finish, the standard top coat plaster (page 12) should be used.) It can then be left unpainted or painted with a vapour permeable paint. > internally for dubbing out (filling hollows) in the wall prior to plastering (to allow an even background for subsequent coats) or for patching old lime plaster. > externally for dubbing out and base coats for a traditional lime or glaster® top coat render.

>> has greater flexural strength than traditional lime plasters making it extremely durable e.g. it is far more resilient for use on corners, reveals and other vulnerable areas of the building.

>> has some thermal properties and can therefore be used to help improve the insulation performance of the wall put in brackets.It also adds to the thermal mass helping to keep buildings warm in winter and cool in summer. >> can greatly improve the air tightness of old buildings, improving the comfort of the room and offering energy savings, (10-15% of heat loss in old buildings is through air leakage and draughts).

>> can be applied in much thicker coats than traditional lime plaster therefore is especially useful for ‘dubbing out’ hollows in walls prior to further plaster coats.

>> is a successful way of ‘patching’ old lime plasters e.g. where electricians/ plumbers have been ‘chasing out’.

>> is easier to use than conventional lime plaster (minimal shrinkage even on high suction backgrounds) offering labour savings.

>> is vapour permeable and therefore helps to regulate humidity safeguarding the functioning and health of the building.

This makes it ideal for use in older buildings.

>> is beautiful - the medium plaster gives a soft textured finish otherwise the fine hemp, glaster® or lime top coat plaster can be used for a different finish

Strength

Insulating

The addition of hemp fibres to lime plaster dramatically improves the strength of the plaster, this gives it several advantages:

The addition of hemp fibre also improves the thermal properties of the plaster over sand lime.

It will not achieve the same performance as some of the other solid wall insulation solutions including cork render - see pages 22-23, but it does offer some advantages including:

> i t is more robust and hence it is highly suitable for use in vulnerable areas (e.g. corners, reveals) within a building.

> less disruption internally.

> i t has less ‘shrinkage’ which means less tending and that it is ideally suited to patching/repairing existing plaster.

Ideal for timber frame infill

> easier to achieve air tightness. > no risk of cold bridging.

> i t also means that for most applications no meshing is required (when applied in 10mm plus coats) and no additional hair is required.

> simplicity and hence far less labour.

Moisture

Availability

The hemp fibres in the plaster actually retain a certain amount of moisture which is ideal for assisting carbonation (curing of lime).

Given the correct environmental conditions.

This also means that it is especially useful for use on ‘high suction’ backgrounds such as blocks where traditional lime plasters might fail.

It is available as a ‘wet’ mix (made with lime putty) or as a ‘dry’ mix (made with hydraulic lime) to which water must be accurately added.

It is a ‘thirsty’ product and so is ideal in timberframe panels as it helps to wick moisture away from the timber.

It is vapour permeable and so helps to regulate humidity, making a healthier environment see below.

The medium hemp plaster gives a substantial textured finish while the fine hemp or glaster® (can be coloured) will give a light textured finish and traditional lime top coat plaster can be used to give a smoother finish.

Bacteria Virus Mould and fungi

Optimal zone

Buildings that are too dry/too humid create ideal environments for harmful agents to thrive which can have an effect on the occupants, we now understand that lime plasters (when finished with a vapour permeable paint see pages 49-64) help to maintain the optimal zone (as shown right) and so contribute to a healthy home.

Why is Relative Humidity important?

tips

It is supplied ready to use and can be mixed in an ordinary cement mixer. The premixed products offer consistency of mix as well as a cleaner site and minimal waste.

It should be painted with a vapour permeable paint (see pages 49-64).

It can be applied onto brick, cement block, concrete or stone masonry substrates. Surfaces may need a consolidation/pricking up coat of REABILITA Consolidation Plaster to act as a key for the ecoCork render. The ecoCork render requires a 3mm top coat of REABILITA Cal Finishing Plaster. The Cal Finishing is designed to be sponge finished and should always be used externally. Internally you can, if desired, top coat the ecoCork with 6mm of T y-Mawr’s ˆ Lime Hemp Plaster (fine) for a robust finish allowing wet edge corners. Changes in substrate and lintels in the wall etc. should be meshed within the plaster.

Winner of the All Wales LABC Building Excellence Award 2013 ‘Best Technical Innovation’.

History Lime has a proven track record in its use in floors having been used since Roman times in foundations and with pozzolans in lightweight concretes. It was used extensively throughout Britain in lime-ash floors, many of which survive today.

Development & Description

tips If the building is statutory listed then listed building consent is required for the removal of existing floors.

Since the launch of our innovative limecrete flooring system in 1998 as a breathable, lightweight alternative to cement-based concrete, our latest flooring system, Sublime®, makes the most of technical advances in recycled foamed glass gravel.

The GLAPOR Foamed Glass is the most structurally and thermally superior product we have ever supplied for floor applications.

By using GLAPOR Recycled Foamed glass gravel within the insulation layer of your floor savings can also be made on installation costs due to its ability to compact to a weight bearing surface. The GLAPOR foamed glass gravel also offers the benefit of being more ‘sustainable’ as it is manufactured using 100% recycled glass.

We are proud to have developed a breathable, sustainable floor system designed specifically for use with underfloor heating, although it is equally suitable for those without ... ‘Sublime®’ The Sublime® floors breathability makes it ideal for use within existing solid wall properties however, its excellent environmental credentials along with its simplicity and ease of installation makes Sublime® an equally appropriate choice for new builds and extensions!

Customer confidence in our systems is vital which is why at T y-Mawr ˆ we invest heavily in product testing and certification. Our Sublime® floor system, carries its LABC Registered detail.

Benefits

>> Lightweight, low impact construction: Ideally suited to sensitive sites such as churches over archaeology

>> Clean, crisp installation: The recycled foamed glass gravel takes the place of separate hardcore and insulation in a conventional concrete floor.

The construction capabilities of the gravel eliminates the need for a separate slab and screed. >> Meets building regulations even without a Damp Proof Membrane: the recycled foamed glass gravel manages low level moisture without the risk of forcing it to the base of walls

>> Improved energy efficiency and response times of under floor heating systems: As the insulation material is directly beneath the heat source the heat drift associated with other systems is significantly reduced.

Our research has suggested that the considerations applicable to cementitious concretes with regard to expansion joints are not applicable to lime based concretes.

Hydraulic Lime generates little heat during the initial chemical hydraulic set and limecrete has a good flexural strength to compressive strength ratio.

These properties mean that huge savings can be made in terms of the labour and equipment usually required to fabricate dowelled and induced contraction joints in cement concrete ground bearing slab. For further information contact limecrete@lime.org.uk

Glapor perimeter insulation bricks provide a revolutionary way of new-build floor construction. The bricks are laid on strip foundations forming insulating formwork and vertical frost protection. Geotextile is then laid inside and Glapor foam glass gravel is loose filled and compacted ready for the floor slab. A quick and easy, time-saving installation process!

Floor finishes Our Limecrete floor can be finished in a variety of ways; If you are purchasing tiles/slabs/ floorboards etc. from a floor supplier we recommend you follow their advice where necessary.

For laying stones and tiles we have a variety of solutions depending on their size and thickness:10mm thick tiles/natural stone laid on a level screed with Secil Adherevit – full bed (coverage 3.6m2 per bag @ 10mm combed bed).

20mm thick tiles/natural stone laid on a level screed with Secil Reboco – full bed (coverage 1.7m2 per bag @ 10mm combed bed).

tips If the backs of tiles/ stones are very smooth/polished then we recommend these are physically keyed before laying.

Very absorbent tiles/ stones will require wetting down before laying.

Fine grouting between tiles/stone can be carried out with REABILITA Cal Finishing (can be pigmented on-site) – larger joints with NHL3.5 and T y-Mawr ˆ Cumbrian aggregate.

Other finishes (compatible with Limecrete – floor slab must be dry before installation) >> Carpets (preferably without rubber underlay) >>Linoleum

>>Laminate floors >>Floor paint

Installation It is not unlike laying a conventional concrete floor; a contractor used to using hydraulic lime products and with experience of laying floors should be willing and able to install it.

Excavation, layer depths and full installation instructions are supplied with the flooring components. T y-Mawr ˆ is renowned for its product support, including telephone support and site visits.

Mixing Limecrete can be done in a conventional drum cement mixer, forced action mixer or, for larger floors, a volumetric batching unit on a lorry. Contractors should be aware that the mixing time is longer than cement (20 minutes per mix after the last addition of water).

Approximate Coverage 12-18 m2 per litre, strongly dependant on the absorption properties of the application surface.

Radon

Design

The Limecrete floor system can be used successfully where radon protection is required.

Go to www.ukradon.org to view a map of your area. For advice contact the BRE www.bre. co.uk – they recommend venting radon with solid floors - this is generally the most effective method, and in many cases will reduce the radon level to less than one-tenth of the original level, sealing the floor with a radon membrane is another solution but it is likely to be effective only at moderate radon levels, up to 400500Bqm-3. Generally, it is difficult to reduce the radon level to much less than half by this means. If a membrane is requested then this is installed above the compacted GLAPOR Recycled Foamed Glass so you retain the benefit of its ability to manage moisture without pushing out to the walls.

Our team are able to design your floor to meet the needs of your specific building, ensuring that you get the best performance for your building and as well as meeting building regulations if required. If you wish to take advantage of our free calculation service please go online to www.lime.org.uk to carry out your floor calculation.

tips Where timber floors are to be laid over screed the moisture content of the screed should not exceed 2 – 3%, which can be checked with a moisture meter. Alternatively tape several clear polythene sheets, each 1 sq.m in area, in various places across the floor and leave for 24 hours.

If there is no moisture present under them then wood flooring can be laid. Timber should have a moisture content of 6-9% and the building should be dry – this includes walls as well as floors. Take advice from your floorboard supplier.

Buildings and the Environment Buildings have a profound effect on our environment; more and more of our clients are recognising this and hence the rationale for using environmentally-friendly building and decorating materials.

The following help to illustrate this:

Tˆy-Mawr’s demonstration house at the NEC.

>> buildings are responsible for a large proportion of Carbon Dioxide emissions in this country - 50% results from energy used in buildings, 10% from their construction. >> The Environment Agency’s trend data shows that around 2.5 million tonnes of C&D (Construction and Demolition) waste were handled in 2007 by waste facilities in Wales. Nearly half of this waste was landfilled, and only eight years of landfill space remains in Wales.

>> t he development, use and maintenance of buildings result in the consumption of 6 tonnes of building materials per

person per year in the UK. If we all choose low impact materials, we could really make an enormous difference!

T y-Mawr ˆ is one of the longest established and most innovative companies in the green construction market in the UK today, a market that is predicted to see tremendous growth (22.8% per annum until 2017). T y-Mawr ˆ has contributed products such as glaster® and lime hemp plaster to the green construction industry as well as systems such as sublime® and more recently has received LABC registered details for their timber-frame, warm roof, external and internal wall insulation systems that all use exclusively environmentally-friendly, breathable materials. The next 6 pages present these systems in detail.

New Timber Frame - Increasingly, self builders as well as housing developers are looking for more sustainable, practical solutions for new builds not only to meet government targets to reduce the impact of buildings on the environment but also because they recognise that it is possible to have improved comfort levels in these constructions creating healthier buildings as well as saving energy costs.

Boards & Insulation Energy Efficiency In Old Buildings Courtesy: Royston Davies

Historic buildings, from 1930s semis to Victorian terraces, Georgian townhouses and medieval farmhouses, are by their very survival, sustainable.

Heat Loss in Old Buildings If these buildings are functioning correctly and, most importantly, are dry they can provide a comfortable living environment fit for the 21st century. Large rubblestone walled properties benefit from thermal mass; being warm in winter and cool in summer. The old adage of if you have an old stone house it is bound to be damp (so you have to live with it) is largely a false perception. If you deal with the root cause (water) for example addressing the roof structure, gutters, downpipes, land drains, soil levels, ventilation… then there is no reason for your property to be damp. Drying a wall can provide tangible benefits for a dry wall can be up to one third more thermally efficient than a wet wall.

For many properties, simple repair and maintenance and the reinstatement of lime plasters and paints will provide all that is required, or indeed all that is desirable.

The key to a healthy comfortable home is to balance temperature, humidity and ventilation and not be blinkered into pushing to achieve a certain u-value alone.

There are many cases where, after the building has been brought to this healthy functioning state, you can consider appropriate and considered methods of improving energy efficiency through insulation. T y-Mawr ˆ is at the forefront of researching and sourcing various materials from across Europe in order to achieve this task. It is clear that this can only be done with the knowledge of how buildings function, the fundamental understanding of differences in solid walled construction and cavity wall construction and the historic and architectural merit of such buildings.

We have keenly followed and contributed to some of the testing, analysis and best practice from organisations such as the Society for the Protection of Ancient Buildings, the Institute of Historic Building Conservation, Historic Scotland and Historic England amongst others as well as working with our suppliers to provide a sound understanding of how old buildings perform in practice, not just theory. Significantly solid walled buildings perform much better in in-situ U-value measuring than modelling software suggests. We were concerned that ill-informed and inappropriate retrofitting of insulation systems would cause more harm

25% through the roof

15% through draughts and windows

45% through walls

15% through floor

than good. It is not just a matter of choosing ‘breathable’ materials, but how and where you use them. Retrofitting should not be at the detriment to the function, character or appearance of a building.

Through training, consultancy and expert advice (see p. 70) we are available to advise on a whole host of options for the householder, architect and developer. Benefitting from a large array of available materials we can guide you through simple repairs and reinstatement to insulating plasters and renders to full insulation systems for floors, walls and roofs. We not only have a track record of supplying these materials over 20 years, but have developed award winning systems with Local Authority Building Control registered details to enable the use of appropriate materials to be much more widely accepted and accessible to all.

Our systems apply equally to sustainable new-build with our insulated Limecrete floors, to modern timber frame solutions and warm roof insulation systems.

The following pages guide you through the materials, systems and their application to enable you to achieve a healthy comfortable home for the future.

tips Heating our homes is one of the most energy hungry things we do, so good insulation is one of the best ways to reduce our CARBON DIOXIDE emissions.

Boards & Insulation LABC-Registered Insulation Systems Solid Wall Insulation Solid Wall Insulation - In the UK, 1 in 4 of our homes has ‘solid’ walls, around 45% of the heat lost in an un-insulated solid walled home is through the walls.

In the drive towards energy efficiency and carbon savings, we are all being encouraged to insulate our homes but solid walled buildings need to allow moisture to evaporate and therefore any insulation solution must work in the same way as the building to avoid the problems that we now know are associated with trapped moisture (see page 2). If all solid walls were insulated there would be a massive carbon dioxide saving of 16,000,000 tonnes per annum (equivalent to the emissions from 2.7 million homes for a year).

>E xternal Wall Insulation - is installed from the outside effectively wrapping the building. This type of installation method may change the physical appearance of the building (which will usually require planning permission) and will necessitate the removal of rainwater goods and may require adaptation of the roof and wall junctions as well as window and door openings as the wall is effectively being made thicker.

It is important to understand that there is not a standard off the shelf solution for all buildings and products should be specified on a building by building basis. For more information on our consultancy service (see page 70).

Celenit Wood Wool Boards

Celenit is one of Europe’s leading manufacturers and suppliers of environmentally excellent insulation made from mineralised fir wood-wool bound boards.

To guarantee constant quality, Celenit has developed probably the most innovative production plants in Europe.

The panels produced conform to European UNI EN 13168 and are CE marked. The quality management system operated by Celenit is in compliance with the standard UNI EN ISO 9001:2008 (certificate No. 1351).

Reed Mat - is lathing supplied in a roll.

Reeds from managed reed beds are laid parallel and bound using narrow gauge zinc wire to form a long sheet.

It is suitable for internal use as a base for plastering on walls and ceilings. It can be used against a solid background or over studs or joists as a practical alternative lining material to gypsum plasterboard and lath-and-plaster.

Reed mats are particularly suited to using with lime, clay or gypsum plasters in building restoration and new-build.

Reed Board – is a semi-rigid building board.

It is made from natural reeds laid parallel and tightly bound using thin gauge galvanised wire.

It is suitable for internal use as a base for plastering on walls and ceilings.

It can be used against a solid background or over studs or joists as a practical alternative lining material to gypsum plasterboard and lath-and-plaster.

tips Reed is a versatile material, as well as its well-known use as a thatching material it has been used in lime floors and as a lime plaster carrier for centuries.

38

The 20mm board can be used as a curved backing for plaster.

It can also be used unfinished to create feature walls, as an insulation board or to act as permanent formwork.

It can be used externally in landscaping schemes to form natural partitions.

Benefits >> helps to keep buildings cool in summer and warm in winter. Cool in summer when the outside temperature increases and begins to heat the wool, it releases moisture; that has a cooling effect on the fibre which reduces the flow of heat to the inside of the building.

This can reduce peak temperature by up to 7°c. Warm in winter - the absorption of moisture by wool insulation can increase peak temperature by up to 4°c when compared to buildings in which alternative forms of insulation are installed.

>> can absorb and desorb water vapour without compromising its thermal efficiency. It is therefore ideal for use in roofs, timber frame and solid walls as it avoids a damaging build-up of moisture by allowing water vapour to migrate through the structure (see pages 30-33). >> uses only 14% of the embodied energy that is used to manufacture glass fibre insulation, therefore paying back its manufacturing energy cost seven times faster than glass fibre.

>> is harmless and can be installed without gloves or protective clothing.

>> has a life expectancy similar to that of the construction in which it is installed; other cheaper modern installations have a lesser life expectancy, making the whole life cost of wool much closer to those materials. >> e xclusive to T yˆ -Mawr, of the wool content, we can guarantee that there is a minimum content of 75% Welsh wool in the T yˆ -Mawr THERMAFLEECE® original and cosywool products.

See www.lime.org.uk for technical data and latest prices

>> can be recycled for other environmentally friendly applications at the end of its useful life. It contains no permethrin, pyrethroids, pesticides or formaldehydes.

>> it has a higher fire resistance than cellulose and cellular plastic insulants; it does not burn but rather melts away from an ignition source and extinguishes itself. T yˆ -Mawr THERMAFLEECE® is treated with a natural fire-proofing agent to improve its intrinsic fire resistance and complies with BS 5803-4 (Spread of Fire) achieving results of zero for ignitability, spread of flame and heat evolved. >> is protected against attack by moths and beetles using a borax treatment.

Borax is a natural mineral salt that is used in a wide variety of applications.

The use of borax to treat wool is extremely safe and poses no risk to people or the environment. Our wool is treated with borax at the wool cleaning stage to ensure a consistent treatment that penetrates deep into the wool fibre.

>> has excellent acoustic properties which means that it can now be specified as part of your noise control scheme - 100mm between floors and partition walls will meet current Building Regulations Part E. >>h as been successfully installed in thousands of square metres of loft, wall and floor applications.

>> available in roll format (Cosywool product) and in a higher density product (Ultrawool) - see opposite!

Of the 400 million tonnes of building materials used in the UK each year – 109 million tonnes are destined for landfill – it is vitally important to consider how durable the material you are purchasing and installing is as well as how it is going to be disposed of at the end of its useful life. Wool insulation is expected to last 60 years or the life of the building and so will not need to be replaced as often as other more conventional insulation alternatives.

There is much excitement about the potential of hemp in many products. >> it grows several metres within months, infact it is the second fastest growing plant on earth (next to bamboo). It grows 4m within 100-120 days. >> it is versatile - it can be used to produce over 30,000 products most are nontoxic, bio-degradeable and renewable! >> it is 10 times stronger than cotton, it naturally repels weed growth and hemp has few insect enemies which means it requires no herbicides and few or no pesticides whereas cotton requires enormous pesticide use. Hemp also produces twice as much fibre per acre as cotton! An area of land only 25 miles by 25 miles square planted with hemp can produce enough fibre in one year to make 100 million pairs of denim jeans!

>> it is a great source of high-protein oil that can be used to make highly nutritious tofu, butter, cheese, salad oils, as well as shampoo, skincare products, paint, varnish, ink, lubricating oils, and plastic substitutes. Because 50% of the weight of a mature hemp plant is seeds, hemp could become a significant source for these products.

INS-TH100370 >> it can be used as clean biomass.

It has more potential as an energy source than any crop on earth e.g. it is estimated that if hemp was widely grown in the U.S. for fuel/energy, it could supply 100% of all U.S. energy needs!

>> it is used in buildings due to its natural strength, flexibility and durability, it has been widely promoted as part of the potential solution for achieving low carbon buildings. Given the right conditions, it is resistant to rot, is fireproof, waterproof, weather resistant and importantly provides insulation!

Hemp lime plaster is easy to use and can be applied in much thicker coats than conventional lime plaster hence offering labour savings! It is also much lighter than sand plasters and so has transport savings too! >> it absorbs carbon dioxide, for every kg of hemp produced, 1.4kgs of carbon dioxide is absorbed and locked in.

In fact, many people now believe that the benefits of hemp are so intense that it has the capacity to reverse the Greenhouse Effect; as well as aid in purifying the air, water and soil.

Airtightness & Windtight Systems

General airtightness tips Tip 1

If there are downlighters involved in your build which break the airtight envelope, you will need to create an airtight seal around them using Optime Downlight Housing boxes.

Tip 3

Use Kaflex Cable grommets for points where cables break through the buildings airtight envelope.

Tip 2

Wherever pipework breaks through your airtight envelope use Roflex pipe grommets for a secure and versatile fully airtight seal.

Note: This is a basic introduction to achieving airtightness & vapour control in buildings. pro clima solutions provide a permanent airtight seal, but rely on correct and accurate installation.

Paints & Finishing Products Introduction to Natural Paints Painting is an integral part of the building process. Care should be taken to use paint with the appropriate characteristics for the job. Paints are designed not only as a decorative finish but as a protective coating.

Ty-Mawr ˆ has carefully designed and selected a unique range of high quality, high performance paints for the DIY and professional market.

As more and more paints come on to the market, it is important to understand what you technically require from your paint as well as considering how it is made. The table on pages 50-51 gives an overview of the main options internally and the selection table on page 57 gives some options externally.

The Ty-Mawr ˆ colour range - colours from the Welsh landscape This new colour range has been developed from research into the indigenous colours of Wales. Three categories of colour were studied: mountain colours, valley colours and coast colours, with a view to developing palettes for buildings to have a sense of belonging in their landscape and for harmonising interior design.

These were recorded using the Natural Colour System (NCS), a very accurate classification for the identification of perceived colour.

(For further information www.ncscolour.co.uk).

Selecting colours and designing palettes based upon the colours found in the natural world helps to reinforce a sense of local identity.

Benefits of the Ty-Mawr ˆ paint range >> they are made from environmentallyfriendly, renewable materials; conventional paints are still often based on petro-chemicals (causing huge environmental problems) and fossil fuels like crude oil (that are too precious to burn). >> there is no human health hazard to users or those living and working in the space afterwards. >> VOC-free (volatile organic chemicals!) naturally.

>> their products have a full declaration of ingredients unlike many of the paints claiming to be ‘green’ on the market today. >> they are highly vapour permeable and therefore compatible with other natural and traditional building materials.

They can directly help to regulate humidity within a building.

>> Ty-Mawr ˆ range of colours is uniquely selected from those naturally occurring in the landscape. >> mixed to NCS colours.

The use of colour in the natural environment compliments Ty-Mawr’s ˆ commitment to thoughtful design and our holistic approach to environmental conservation. It is fitting that paints which work with the environment, allowing buildings to ‘breathe’, should find their provenance in bedrock, vegetation, earth and sea.

Ty-Mawr ˆ have developed this concept to provide a range of technically excellent silicate mineral paints and plant-based emulsions for exterior and interior use respectively. Limewash colours can also be categorised within the NCS spectrum. This colour range helps to integrate buildings into their landscape setting, and draws natural colours to the interiors of homes creating strong associations with the land upon which they sit.

Paint and Varnish Remover

Home Strip is an extremely effective water-based, vapour free paint, varnish and coatings remover based on dibasic esters.

Home Strip has a slightly longer dwell time than more dangerous solvent based strippers based on Methylene Chloride and NMP. It allows the removal of up to 5 coats in one application. Clings 100% to vertical surfaces.

No discolouration of timber, washes off with just water. It does not dry out after short periods of time, allowing large areas to be stripped successfully, unlike some solvent strippers which quickly evaporate. Because Home Strip does not give off any fumes, there is no need to work out of doors or ventilate the area by opening doors and windows as you would with solvent strippers.

Suitable for all woods, metals, stone, brick, marble, GRP (Glass Reinforced Plastic) etc.

Recommendations: try a small test area first.

Paints & Finishing Products Internal Mineral Paints

Courtesy: R & M Williams, St John’s Church

Mineral paints have been manufactured in Germany from waterglass for well over 100 years. Their popularity throughout Europe is based on their incredible durability as they actually bond to the surface to which they are applied - becoming part of the fabric of the building. Just as importantly, they function in the same way as the building i.e. they continue to let older buildings ‘breathe’.

They have therefore been widely used amongst professionals involved in old and historic building conservation. As they have no artificial resins, solvents, biocides etc, they are also the choice of those concerned about the health of the painters and building occupants as well as those concerned about the environment.

The product range is extensive, with paints that can perform in a huge variety of situations and on different backgrounds (outlined here for internal paints and on pages 57-59 for the external range).

New Chart now available - call for your free copy!

Benefits

>> they have an excellent historic pedigree dating back to 1884. >> mineral paints actually form active silica bonds with the background (i.e. they become part of the background).

This is what gives them such incredible durability.

>> they have a “breathability” (water vapour permeability) comparable to limewash (with an Sd value of <0.02m), which results in healthier and drier buildings. >> they are completely non-toxic and contain no VOC’s, this makes them safe for you and your family to work and live with.

Please note these paints rely on a natural chemical reaction occurring to perform at their best - this requires the right primer to enable the silification process to take place - see table on pages 50-51. Always refer to the technical sheets.

INSIL Internal Paints – a solvent-free, open pored interior silicate paint. This paint is not a pure silicate – it has 4% artificial resin which helps it to bond to difficult surfaces e.g. where modern emulsion may have been used. It is still highly vapour permeable and therefore ideal for rooms with a variety of backgrounds e.g. new plaster with old painted walls. Apply fixative to prime new lime plastered walls (see table on page 50-51).

Painting

Apply two coats of Beeckosil diluted with Fixative (20% first coat, 5% second coat) using a mineral brush or sprayer (if experienced). It is vitally important to apply it evenly keeping a wet edge going so that it is lap-free. Complete single elevations in one go. Allow at least 12 hours to dry. Avoid painting in wet or cold weather (below 5째c).

Apply Fixative thinned with 2 parts water.

If stone/brick is absorbent apply Fixative thinned with 2 parts water

Apply two coats of RENOSIL Coarse/ Fine. First coat diluted with 10% fixative, second coat with 5% water.

*For new concrete, mould oil remover should be applied followed by Beeckosil (dilute with 10% Fixative for first coat and 5% second coat).

Surfaces should be clean, dry, stable, salt and plant-free before applying the Beeckosil system. The paint does not hide differences in the background, therefore correct products should be chosen and all products must be carefully and evenly applied.

It is ESSENTIAL that full technical sheets and application guides are consulted and test panels undertaken to ensure suitability.

This table indicates the steps for most usual conditions, and is for basic guidance only. For any other surface, please contact us for application guides and technical sheets at tymawr@lime.org.uk.

T y-Mawr ˆ Limewash A traditional mineral paint made from fat lime putty. It “sets” when exposed to carbon dioxide in the air. It is the ideal paint to use on lime plaster, masonry, brick etc as it is highly vapour permeable. It has a matt finish and a ‘depth’ which most modern paints lack. It reflects light and appears to ‘glow’ in sunlight.

T yˆ -Mawr Limewash is available as a creamy off-white or a bright white to which pigments can be added. It is also available in a range of colours - see below, or we can tailor-mix a specific colour for you (see page 61).

In some circumstances, it may be necessary to help limewash bind (eg very exposed conditions). Casein, tallow, Uniprotect or raw linseed oil can be added for this purpose, but remember that additives may compromise the ‘vapour permeability’ of limewash to some extent. Please note we do not recommend the addition of PVA. Limewash can be made up using Natural Hydraulic Lime - we recommend this for areas of high exposure.

A coloured limewash tends to have a slight colour variation across the surface; this slight blotchy effect is quite normal and is generally considered to be part of its beauty.

The adhesion of limewash relies on suction from the surface to which it is applied. It sticks well to lime plasters and renders, stone, brick and similar materials, but does not adhere so well to modern materials and finishes (see pages 50-51 for alternatives).

Depending on the condition of the surface, WHITE it may be wise to apply a shelter coat.

A shelter coat will provide an excellent ‘key’ for the subsequent coats of limewash as often, when limewashing over bare stone, especially YNYS MON if the stone is hard and non-porous, it can be difficult to get pure limewash to stick and/or remain on the surface.

Available in white and the standard colours below, also available in a wider range of colours, please see www.lime.org.uk or contact us for our latest colour chart.

Please note – dust free after 8 hours, safe to coat after 24-36 hours. Must be diluted according to manufacturer’s instructions using balsam lacquer thinners (see page 64).

The absence of acrylic in these paints means that they move and flex with the wood with changes in moisture and temperature without peeling or flaking. They are also ‘vapourpermeable’ and so allow the wood to ‘breathe’.

These properties mean that they are more durable than most modern ‘more economic’ wood paints. (interior, eggshell finish) 3 litres
