These days, natural daylight has become a must-have feature for homeowners and self-builders, as more of us are aware of the beneficial effcects of daylight in our homes. This, of course, is great for our rooflight industry, which despite the prevailing econimic climate, is experiencing something of a boom at the moment. The inevitable downside is that there also appears to be a boom among less scrupulous traders, improvising what they claim to be ‘rooflights’, but are in fact nothing of the sort. To spell it out: a standard double glazed unit glued onto a timber upstand isn’t a rooflight; doesn’t perform as a rooflight should; and above all, is a danger to the public: an accident waiting to happen.

NARM, the National Association of Rooflight Manufacturers, is on the case – working hard to draw attention to and ultimately bring an end to this malpractice. You can read their highly informative article on page 17.
On the subject of ‘proper’ rooflights for domestic applications, two of our regular contributors, Peter Daniel of the Rooflight Company and Paul Trace of Stella Rooflight offer their insights into different aspects of the topic, on pages 22 and 31 respectively. Also in this issue, Gary Southgate of Hambleside Danelaw looks at design considerations for GRP rooflights for industrial buildings on page 14. There’s a different take on daylighting on page 29. Sun tubes provide a solution in applications where the roof structure makes conventional rooflights unsuitable. This case study from Techcomlight, sheds light on an example in the Netherlands. I hope you’ll enjoy the issue – any feedback is always gratefully received.

Building Standard starts to take effect
The £69.9 million building features aluminium panelling which is less carbon-intensive in the design and construction phase and aims to achieve BREEAM Outstanding and Energy Performance Certificate A rating. It will also be Net Zero Carbon, using the UK Green Building Council Framework The significant investment needed to meet the new Standard should help support private office construction activity, a sector where Glenigan is forecasting a 10% rise in the value of new starts this year followed by a 7% rise next year and a further 16% increase in 2024.
The rise in fuel costs has moved energy efficiency increasingly onto the radar of both major private developers and landlords as well as occupiers of business space. It has been reflected in the growing number of new projects built using the sustainable BREEAM route and will be reinforced by the new AheadStandard.of the goal to cut emissions in non-residential new buildings, the introduction of the new building regulations in June appears to have impacted short-term activity in the private commercial and industrial sectors.
Yet private commercial property owners particularly on smaller buildings may need some further government help to achieve the targets involved in the new LastStandard.month
A planning application by Peel Media for a major new 11-storey office building at MediaCity in Manchester - where Landsec owns a 75% stake - gives a pointer to the new emphasis on energyefficiency in commercial buildings which is being partly driven by the new Standard.
INDUSTRY NEWS
Glenigan has reported that tne of the first steps in a major new government initiative to cut carbon emissions - which will involve sweeping changes for the construction industry - was taken in June when various changes to building regulations were introduced ahead of the Future Homes and Building Standard. The new Standard is set to come into full effect in 2025 with a goal of dramatically cutting carbon emissions in new homes by 7580% on current levels. Inevitably, this will mean new homes built by both private and public developers will have to meet more demanding and potentially costly standards. But the new Standard will also extend to existing homeowners who are undertaking extensions or renovations involving thermal Theupgrades.non-residential construction sector will also be impacted. Developers of new offices, retail premises and public authorities will be obliged to meet new standards with a target to cut emissions by 27% over coming years. Already, there are signs that commercial developers have brought forward the start of some new schemes this spring to avoid some of the new regulations which came into force in June. In the medium term, contractors working in the housing renovation and refurbishment sectors should see stronger demand for their services as clients are obliged to meet more exacting standards. The new standard could also bolster demand for newly built commercial and office space.
Yet as with private housing, the introduction of the new Standard is likely to bolster the value of construction activity in the commercial and industrial sectors in the longer term as fuel bills become increasingly significant for Majoroccupiers.developers such as Landsec, the country’s largest commercial developer and Hammerson, the retail developer and landlord, have pledged to reach net zero on emissions across their estates by 2030.
The latest Glenigan Index shows that office project starts in the three months to July fell 42% compared to the previous three months and industrial starts were down 26% on the same basis.
the British Property Federation urged the government to increase tax relief for capital expenditure on building projects to support its net zero ambitions with a new tax credit system along similar lines to the existing one for R&D spending.

It is now almost a decade since the Law Commission launched its review of Rights to Light, and there is still no sign of a government response to its recommendations, whilst analysis technology continues to develop. New Daylight & Sunlight guidance has emerged (BRE, June 2022), while new market entrants have significantly affected the professional and insurance landscape.
Built to coincide with the summer solstice (Tuesday 21 June), the day with the longest period of continual sunlight in the northern hemisphere, the launch of Light Knights comes at an important moment for the industry. The club will also be holding events around spring and autumn equinox.
In this context, Light Knights was proud to host representatives from across the industry, attended by the Law Commission, practitioners, solicitors, insurers, architects and software providers, at its first ever function – held at The Counting House, 50 Cornhill, London.
Rights to Light industry joins together with “statement of intent” at inaugural Light Knights event
While RICS has offered an APC pathway to chartership specifically for those working in the Rights to Light industry, until now there has been no professional network of support for Rights to Light practitioners.
Light Knights, a newly launched industry group created to promote best practice in the field of Rights to Light and Daylight & Sunlight Amenity, held its inaugural event on 16 June, bringing together almost one hundred specialist practitioners, policy makers and stakeholders from across the built environment sector.
“We’ve seen the success and impact that related disciplines have achieved in this way, not least the sterling work of the Pyramus & Thisbe club, and we hope that Light Knights can, over the long term, continue this heritage of professional camaraderie and mutual advantage in the wider surveying sector. It was certainly a real pleasure to see so many new and familiar faces at our inaugural event. It was a real statement of intent, and I am hugely grateful for, and encouraged by, the industry’s response – including from our 200+ group followers on LinkedIn.
Dan Tapscott, Founder of Light Knights and Partner at property and planning consultancy Rapleys, commented: “Rights to Light and Daylight & Sunlight have been in the shadows for too long. It was time that the industry came together to exchange ideas, agree best practice principles, and help to support and educate each other, and the next generation of practitioners entering the field.

“What this means in practice is that Rights to Light must be considered early in the development process in tandem with considering Daylight & Sunlight Amenity. Risks should be mapped and mitigated so that any claims that do arise further down the line can be managed effectively. Rights to Light practitioners will, by necessity, be more involved in the early stages of development, and in more depth, armed with the latest innovative technology to assess sites and professional expertise to inform dialogue with neighbours.
“Light Knights has been formed to assist and support practitioners working in, and entering, this evolving market. I’m excited for what the future holds for our discipline, and look forward to working with colleagues and peers through Light Knights, to continue to advance our profession.” Light Knights is sponsored and supported by property and planning consultancy Rapleys. www. rapleys.com ISO Chemie, a leading producer of foam sealant tapes for windows and doors, has secured an international energyefficiency certificate for its multifunctional joint sealing tape, ISO-BLOCO Hybratec. Awarded the ‘Certified Passive House Component’ label by the Passivhaus Institute in Darmstadt, Germany, the tape can now officially be used in the construction of passive energy houses across the UK and Europe as a window connection air tightness system. In tests, the tape was found to have excellent air tightness and thermal protection when it came to the sealing between the inner room and external climate. Uncontrolled convection heat losses and draughts via the connection joint can be effectively eliminated - an important requirement in energy-saving construction. ISOBLOCO Hybratec also combines considerable expansion force with excellent functional reliability in terms of capacity to absorb long term movement and expansion of windows. As an independent body, the Passivhaus Institute in Darmstadt tests and certifies products with respect to their suitability for use in passive energy houses. Products bearing the ‘Certified component’ quality seal have been tested against standardised criteria, have comparable characteristic values and offer excellent thermal quality.

Design Considerations when Specifying GRP Rooflights
“Although rooflights should never be walked on, it is expected that they achieve a non-fragility rating to reduce rooflightfallingassociatedriskwithontotheassembly.”
In the early stages of building design, it is important in a fabric first design strategy to assess key materials and determine what it is that those materials need to deliver. Often rooflights are overlooked despite offering a wide variety of proven benefits. Correctly specified, Hambleside Danelaw’s Zenon GRP rooflights can not only satisfy regulatory requirements, but also capture the essential essence of natural daylighting. Below are some key attributes of GRP rooflights that must be considered prior to the specification stage. Non-Fragility Although rooflights should never be walked on, it is expected that they achieve a non-fragility rating to reduce risk associated with falling onto the rooflight assembly. All Zenon GRP rooflights are tested in accordance with ACR[M]001 Test for Non-Fragility of Large Element Roofing Assemblies. Fire Performance An equally important consideration when specifying GRP rooflights is fire performance. Regulations relating to fire are under constant review, but current information on regulations and Zenon GRP rooflights can be found in our dedicated document. Thermal performance U-Value is used to measure the thermal transmission of a building envelope assembly. GRP rooflights often feature a polycarbonate insulation layer to comply with Building Regulations minimum requirement of 1.8W/m²K but it is becoming increasingly common for buildings to target even lower U-Values. This of course will need to be balanced with the rooflight’s light transmission levels as additional layers of polycarbonate sheet result in lower light Zenondistribution.Insulatoris a sustainable way of decreasing the U-Value, without compromising that all-important light transmission.

Building Use The hours in which a building will be in use is another important consideration. This will affect key decisions made about the building design. During www.daylightingmag.co.uk
Light Transmission It should go without saying, but GRP rooflights should provide the best levels of natural daylight possible. It is shown that incorporating rooflights into the building design can result in up to three times more natural light in the internal space than a window/vertical glazing of the same size. Natural daylight results in a happier, healthier and more productive work environment; for more information on how natural daylight can benefit the building occupants, take a look at NARM’s Quickguide.
GRP ROOFLIGHTS acetate (a recycled wood pulp), Insulator has a honeycomb structure which runs perpendicular to the plane of the rooflight, resulting in increased light transmission and diffusion. Critically, from an environmental standpoint, Insulator can be composted at the end of its service life. G-Value G-Value, also known as solar gain, is the directly transmitted solar heat and absorbed solar radiation, which enters the building through a material. Solar gain and light transmission are closely linked – it is impossible to have one without the other. Therefore, when planning a building with high levels of natural daylight it is important to consider and address the solar gain that will inevitably be created.

This may mean that the installation of automated lighting, to respond to varying levels of daylight (winter afternoons for example), a good choice for the building. This will inevitably reduce the demand for lighting energy and associated costs and make the most of the natural daylighting benefits provided by the rooflights. Embodied Carbon The last thing on this list should not be mistaken for the least important. Embodied carbon is fast becoming a key consideration when selecting building components. Embodied carbon refers to the Greenhouse Gases (GHGs) expended during the product’s cradle to grave lifecycle. The embodied carbon figure includes the carbon equivalent of GHGs used during manufacturing, distribution, maintenance, and disposal. Hambleside Danelaw have always considered reducing embodied carbon to be of the utmost importance, which was one of the key drivers behind the development of Zenon Evolution. The manufacturing composition of Zenon Evolution has significantly less embodied carbon than its traditionally manufactured equivalent alternative. Zenon Evolution rooflights can also be used in conjunction with our Insulator honeycomb core to deliver highly efficient - and very low carbon –rooflight configurations. Learn more ...

NARM, the National Association of Rooflight Manufacturers, is the trade association representing the UK’s rooflight industry. Our purpose is to promote best practice in all aspects of rooflight design, specification, installation and maintenance.

Getting rooflights right: important safety & performance advice

What can happen when a DGU is just bonded to a timber frame. On this case, after the inner pane shattered, the outer pane could have just lifted away from the inner pane in the event of a strong wind.
DAYLIGHT IN HOMES
DAYLIGHT IN HOMES manufacturer and installed by a qualified person, to the manufacturer’s guidelines. Never consider fabricating a rooflight on-site using a doubleglazed sealed glass unit (DGU).
The glazing on this rooflight was not properly fixed, resulting in it being blown off in windy weather and ending up in a neighbour’s garden. Luckily, no-one was injured in this instance.
We have seen several instances recently where a DGU has just been bonded to a timber upstand leading to a significant safety risk when a pane has failed. In one instance the unit was ‘stepped edge’ with only the outer pane being supported by the upstand. The seal of the DGU was not structural, yet the inner pane was hanging from it without any other means of support and probably not a silicone seal, causing it to break down due to UV exposure. The seal between the two panes failed allowing the inner pane to just drop from the roof into the room below. It only broke on impact with the floor. If that had hit someone, the likelihood is that they would have been seriously injured, if not killed. In another recent case, both panes were sitting above the upstand. Only the inner pane was bonded to the upstand – and that shattered. It was a toughened glass pane, not laminated, as strongly recommended by NARM for this very reason. After the inner pane shattered, the outer pane could have just lifted away from the inner pane in the event of a strong wind. An additional danger was the issue of the glass fragments falling into the building below. Also, even without any wind to lift the outer pane: the building is no longer secure as the outer pane could just be lifted off the opening. On this installation, there were exposed metal screw heads immediately under the glass. It was likely that contact with these metal screw heads caused the inner pane to shatter in the first place. It’s also worth noting that the upstand was well inside the recommended minimum thickness of 100mm to achieve a 0.35 u-value, so this installation was not only unsafe, but also thermally inefficient. These and countless other similar incidents serve to underline the critical importance of understanding the safety and performance implications of ‘home-made’ rooflights and ensuring that only purpose-made, compliant products are installed.

Here’s what to look for when considering rooflights for your next project: Safety Current British Standards define that inner panes on rooflights must be laminated in applications more than 5 metres above floor level (increased to 13 metres in limited circumstances) or are located over water (eg swimming pools). However, the relevant standard permits use of toughened glass inner panes in other applications, if a risk assessment is carried out and confirmation provided that this does not present additional risk to those below the rooflight.
What makes a ‘fit-for-purpose’rooflight?
DAYLIGHT IN HOMES
The term ‘toughened’ implies a degree of safety which in the case of rooflights, is misleading. Toughened glass inner panes actually bring a risk of shattering and falling into the room beneath. Therefore it’s difficult to see how use of a toughened rather than laminated glass inner pane doesn’t present a risk to anyone beneath a rooflight, whatever the position or height of the installation. For this reason, NARM asserts that any risk assessment of a toughened inner pane is largely Forirrelevant.thesafety of people needing to access roof areas, non-fragility classification should also be confirmed.

Walk-on roofllights are designed and built to floor loadings, to match the surrounding roof area –and are therefore much heavier and significantly more expensive than conventional rooflights.

Thermal Performance Approved Document L of the Building Regulations defines the requirements for Conservation of Fuel and Power by setting the standards for energy performance and carbon emissions for new and existing buildings. This part of the Regulations has recently been updated. In respect of rooflights generally, the limiting rooflight U-value is now 2.2 W/(m2K) when assessed in the horizontal plane. It’s important to note that the quoted u-value needs to be for the whole rooflight, not just glass centre pane u-values, which we still see quoted by some suppliers. Even when just a DGU has been bonded to a timber upstand, the centre pane u-value is not the u-value for the installed rooflight as account has to be taken of the spacer bars and edge seal of the sealed unit, the centre pane u-value excludes these heat losses around the edges. A reputable rooflight supplier would be able to provide these accurate values for their product. Security Part Q Building Regulations state that ‘Ground floor, basement and other easily accessible windows (including easily accessible rooflights) should be secure windows made to a design that meets the security standards of British standards publication PAS 24:2012.’
Other considerations Even a fully compliant, high quality rooflight can be compromised by inappropriate installation methods or standards on site. For this reason, we strongly advise close adherence to manufacturers’ installation guides and reference to any specific requirements relating to roof finishes abutting the Arooflight.simple way to ensure that the rooflights you specify for a project will meet appropriate standards and regulations, is to source them from a NARM member company. Our membership comprises businesses supplying all types of rooflights and NARM membership is only open to businesses whose products are fully compliant. For further information, visit: www. narm.org.uk
A PAS24 certification is a security standard that can only be met once a product has been certified for its security performance. The acceptable security standard ensures that products meet highsecurity performance levels, offering reassurance to homeowners that the entry points to their homes have been rigorously tested and are resistant to break-ins and home invasion. Products satisfying other standards that provide similar or better performance are also acceptable. These standards include: STS 204 Issue 3:2012; LPS 1175 Issue 7:2010 security rating 1; and LPS 2081 Issue 1:2015 security rating A. Frames should be mechanically fixed to the structure of the building in accordance with the manufacturer’s installation instructions.

Rooflight
Peter Daniel, Product Innovation Director at The Rooflight Company, debunks the biggest myths that surround installing rooflights.
Without the right information, homeowners have a few questions when architects specify a rooflight for their project. There are some myths and misunderstandings surrounding them, what follows are some of the biggest misconceptions to help you keep homeowner’s minds at ease: 1. Rooflights make rooms too hot in the summer Homeowners are all too familiar with conservatories and their often poor thermal efficiency and can sometimes believe all light from above will cause the same issue, which can thwart any plans you have to recommend a sunroom or orangery. Whilst this may be the case with poor quality rooflights, it doesn’t have to be so it’s worth reminding them that rooflights with good insulation and thermal efficiency ratings will keep homes warm in the winter and cool in the summer without any additional effort on their part. Talking through U-values and their meanings could also be helpful, because it is all technical jargon that can be a pain for people not in the industry to get their heads around. For example, many people don’t know the difference between whole-unit U-values and centre pane. If they understand that a product with a low whole-unit U-value will offer much better thermal efficiency than old-style conservatories, they are far more likely to see that a sunroom or orangery is a better idea for their property.
Myths and Tips for Buying a
DAYLIGHT IN HOMES www.daylightingmag.co.uk Autumn 2022 23
Homeowners often think, large rooms must need a large rooflight. But this is how they can fall into the trap of having too much light in a room, which can be just as bad as having a dark room. This is a common issue that no one can be expected to predict if they don’t have the experience. Instead, depending on the size of the room, we might recommend opting for several smaller rooflights. Not only do they better control the distribution of light in a room but can be used to add design interest – especially with our bespoke options that can be made in almost any shape.
Depending on whether it’s a singlestorey bungalow or extension, or a multi-storey home, some larger units may require the use of a crane, and most products will arrive on the back of an HGV. So, homeowners need to take the logistics into consideration when planning a project to avoid disappointment when the window arrives, and the delivery driver can’t access the property. If space is tight, just let the manufacturer know as soon as possible, and always ahead of time. They might be able to recommend alternative arrangements.

3. Installing rooflights is difficult It’s true that installing a rooflight takes planning; clambering onto a roof on a whim isn’t a simple (or safe) thing to do, but installation itself isn’t difficult.
4. Rooflights need constant cleaning and maintenance

2. Larger rooflights are better
It is true that occasionally products will show signs of weathering and need light touch maintenance but explaining to them that most high-quality products will come with additional qualities that prevent the homeowner from having to regularly care for them. “Homeowners often think large rooms must need a large rooflight. But this is how they can fall into the trap of having too much light in a room, which can be just as bad as having a dark room.”

Our neo roof windows, for example, come with BioClean glazing as standard, which can also be specified on our Conservation Rooflights. This technology makes glass cleaner and clearer without need for regular window cleaning, making it a good recommendation, particularly for rooflights that will be situated in hardto-reach areas.

5. Rooflights leak While we’re sure that our forefathers who designed the original Victorian rooflight may have suffered some waterproofing issues, high-quality modern rooflights do not suffer the same fate. Perhaps this myth exists because rooflights, particularly if installed horizontally, take more of a battering from the elements than vertical windows. Conservatories have also had a bad reputation for leaking which may feed into this too. In reality, it’s usually poor installation that can cause a rooflight to leak, so it’s more important to advise them on ensuring they use a quality tradesman. This is particularly important if it’s a period property. Buildings with rafters that are hundreds of years old aren’t usually ‘‘square’ anymore so a certain level of expertise is required to ensure a snug Enjoyingfit.the benefits of every sunny day doesn’t have to be a challenge. By debunking these myths for homeowners, as architects and installers you can specify these products with full confidence.

Realisation of a unique experience Techcomlight owner Mark Veldjesgraaf. said:”Twenty-five years ago we started importing the Solatube daylight tube and we have been realising daylight in rooms where windows or skylights are not the solution for all that time.” He continued: “Solatubes were the ideal solution for Daiwa House Modular Europe. Their limited diameter allows interventions in the roof construction to be carried out easily. At the Experience Centre, we used Solatubes with a diameter of 35 cm. Although not necessary for this particular project, daylight can be ‘piped’ further into the building as required with Solatubes. For example, if there is a solar panel or other installation right above the place where you need daylight, the system can be offset by routing the tubing to avoid the roof obstruction. The 35cm system used for this project can be extended up to 15 metres in length.”
Collaboration It is natural for Techcomlight to work together with other parties involved in a project. For Daiwa House Modular Europe, close collaboration with their design and construction team was indispensable. Techcomlight was able to provide targeted calculations and to propose and realise the ideal solution.
Michiel Gieben of Daiwa House Modular Europe is clear about the result of the collaboration and the daylight yield of the Solatubes. He said: ‘The Solatube daylight systems provide a unique daylight experience to the entrance and reception area. In addition, the finish of the daylight systems in the ceiling has a sleek and modern design, further enhancing the feel of the room.’

When does cost outweigh conservation?
It’s hard to imagine a tougher economic climate. Having emerged from the pandemic, businesses and homeowners are beset by the rising costs of fuel and materials, economic shockwaves from the war in Ukraine and stark warnings of 11% inflation from the Bank of England. This is compounded by ongoing building supply issues that are still being experienced as a result of Brexit. As the cost of most building materials such as timber, steel and glass continues to increase, the impact will most keenly be felt among those working on self-build, renovation and extension projects. No doubt, this perfect storm of economic woe has resulted in the postponement of many such project, however, for those that are pressing on, most will be looking to cut back on budgets in whatever way they can and compromises on quality are Fortunately,inevitable.when it comes to the majority of building projects, especially new build or modern homes, there is plenty of choice out there for most materials and components, and shopping around a little can yield
CONSERVATION ROOFLIGHTS
According to Historic England, the public body that looks after England’s historic environment, in their Materials for Historic Building Repairs article “The use of authentic traditional materials helps to retain the character of historic buildings and in turn supports traditional industries and vital craft skills. They argue that “some materials can actually harm the existing historic fabric and speed up deterioration”, and urge for consideration to be given to “the potential durability of the material used and its future maintenance requirements”, they conclude in saying “what might seem like the cheapest option might not always work out so in the long run”. Looking more closely at the rooflight market; just because something is sold as a conservation product, that doesn’t automatically make it suitable for all building types. If a rooflight is going to be introduced it has to meet the conservation specifications of that particular area or type of building. If your building is Listed or in a conservation area then the criteria for using conservation rooflights are much stricter and you should always gain approval, not only for their use but also the manufacturer that you would want to Thereuse.are only a handful of companies that specifically make conservation rooflights and even fewer who design, manufacture and assemble in the UK. Many conservation rooflights available online are simply other products which have been spruced up to look like they meet the requirements of that type of product. There are many elements which go into a genuine conservation design and price is always a reflection on quality. If a conservation rooflight is all frame,
useful savings. However, if your project is historically sensitive, for example a Listed building, barn conversion or a property in a conservation area, then choices may be more limited. There are many examples of imitation ‘conservation’ products on the market, for example plastic being used as a replacement for cast iron rainwater goods, windows and rooflights. While these products might offer a cheaper alternative, there are few, if any examples where these materials should be considered appropriate.

should also be given to the viewable area of a rooflight. Large rooflights do not always guarantee lots of light and you should always check what the finished viewable (often referred to as clear viewable) area of the rooflight will be. You might think that a conservation rooflight with a whole frame size of 900mm (w) x 1200mm (h) would have a similar clear viewable area regardless of the manufacturer, but you would be wrong and bulky framed modern types or the flat rooflights posing as pitched conservation styles will let in considerably less light than a genuine steel framed Understandingversion.whatconstitutes
then there is little point in having one. Genuine conservation designs should be manufactured with slim, clean lines and a low-profile to match the roofline. A number of skylight companies try to produce conservation rooflights using modern bulky aluminium or plastic profiles, which sit proud of the roofline, particularly slate. It is widely accepted that most authentic conservation rooflights are manufactured from steel because it provides great strength while offering a slim profile and excellent glass to frame ratios. There are many types of steel conservation rooflights and for unrivalled protection and lifespan, one should always consider 316 stainless steel, which will protect against the common issue of Considerationrust.
a genuine conservation product is vitally important in an age where we are witnessing far too many cheaper, often imported, plastic products, being used in sensitive buildings across the UK. The use of such products very rarely contributes anything to historic character of a building, indeed the visual impact of using modern materials on older buildings usually has quite the opposite effect. While there is no denying that bone fide conservation products are more expensive - and hopefully the reasons for this have been demonstrated above - builders, architects and homeowners must resist the temptation to use alternative materials when looking at areas in which to cut back on budgets. As we continue to feel the economic squeeze we can only hope that decisions are taken in the best interests of the long term preservation of our heritage and that cost cutting does not end up having a long term impact on our important historical buildings. www.stellarooflight.co.uk
