ED'S NOTE

The new passion It was over three years ago that we first attended the HWZ International Wood Conference in Cape Town.

Needless to say, it quickly became a top event on Timber iQ's calendar, and a firm favourite on my own.

E

very year, the Wood Conference speakers very elegantly complement the given conference theme, and this time was no different. ‘The new passion – create something with wood’ represented a thought-provoking topic for many.

Bernadette Hunkeler Brown, the Swiss Consul General and a guest speaker at the conference, pointed to the theme in her talk, playfully challenging the concept of ‘newness’ in this arena before she highlighted timber’s versatile propensity to be used and worked in both traditional and very high-tech scenarios.

SUBSCRIPTIONS: There is nothing new about man’s passion for wielding all kinds of beautiful and practical things from timber, I thought, much like Hunkeler Brown. Working with wood is as old as the material itself, and I imagine the first of us who walked on two legs being drawn to this hard but forgiving resource, knocking at its fibres, listening eagerly for a response, and hammering out the first imaginings of tools and utensils in our primordial brains.

But a new passion for timber has emerged. Over the past few years, timber’s prevalence in architecture, design, and our daily lives has, quite simply put, exploded. Timber has never been more trendy, more usable, more workable, or more intelligent than it is today. It is a material we can specify and use without burdening our collective conscience, and we can continue to pass on its use to future generations with a sense of pride.

Here’s to revived passions and creativity. Here’s to wood.

Welcome to our first issue of 2015. Enjoy the read.

Jen Postal note: 2015 looks set to be a potentially challenging year for all industries and households with regular power cuts already being implemented and set to continue.

DECKING

When a deck is not just a deck When it comes to designing the ideal timber deck to take up its rightful place in your garden, it's well worth considering the services of a professional.

DECKING

W

ith a multitude of factors to contemplate during the planning phase of that dream deck, it’s easy to become overwhelmed, or worse – to overlook an important dynamic that could seriously detract from either the beauty or functionality of the deck. In this article we take a cue from The Green Zone, whose comprehensive service offering includes landscape design and installation as well as specialized horticultural maintenance.

DESIGNER BEWARE Ilse Herbst is a certified landscape technologist and Maintenance Developer and Designer with The Green Zone in Table View. Her love and respect for nature is evident in her practical approach to gardens, as she shares expert advice on how to incorporate deck design into good overall planning: "For several reasons, it is always advisable to start with a complete landscaping plan for the whole property. That way, should you face budget constraints, the work can be completed in phases. If you were to start off with only the deck but then later decide to add bits and pieces of hard landscaping as you go along, the landscape could end up looking incoherent, like a ‘cut-and-paste’ job.”

The average consumer won’t always know how to bring a great decking idea to life, or be aware of impracticalities. That is where a professional can help. Herbst concurs, “There are often problem areas in a garden, which can include rocky or polluted soil, instability in the sub-layers of soil, steep slopes that have suffered erosion, ugly foundation pipes, etc. Being able to perform a site analysis allows you to do an overlay plan on the existing plan. You can then ‘zone’ the different areas of the garden. The most sensible approach is to select the bad areas for hard landscaping or decking and to leave natural planting and trees intact.”

DECKING

BALANCED BEAUTY When designing the deck, Herbst further clarifies, it is preferable to balance the scale relationship with the soft landscaping (planting). If the deck is to be installed in a garden, the overall style or theme of that garden must be taken into account. Case in point, a deck of asymmetrical design could quite beautifully accentuate and further define the shape of the garden design.

Some questions worth answering: • Will the deck mirror the lines of the house?

• Will a formal deck fringe on a wild, natural garden with organic shapes, or planting, which is equally formal?

When different levels or terraces have been integrated into a garden’s design, the result can be very appealing, making the space more interesting and creating private garden ‘rooms’ and viewpoints. Similarly, and as an alternative to moving soil and creating berms, installing a well-designed, well-placed deck can be a great way to achieve that tiered effect. The deck doesn’t have to be at one level only – a deck with multiple levels means they can be used at different times of the day and even during different seasons.

Deck boards offer another way to balance practicality with intended aesthetic design. For example, among choices of broad versus narrow, ribbed or grooved, etc., grooved boards are a better choice for high-traffic areas such as shopping malls or pedestrian bridges because they can help reduce the risk of people slipping.

And here’s another interesting and helpful tip from Herbst on layout: The direction in which the deck planks are laid creates a design illusion. If laid out horizontally, the space is made to look wider, which is good for long, narrow decks. If vertically placed, the space will appear to be longer.

CIRCULAR TIMBER PLATFORMS

DECKING “For example, most fynbos species like Proteas and Pincushions require full sun to flower and to remain disease free.”

Something else to consider, depending on your local climate and other factors, is the type of timber to select for your deck, as well as the appropriate treatment it will require to remain durable and give you many, many years of enjoyment. Timber iQ recommends the following industry bodies for assistance in this regard: • The ITC-SA (Institute of Timber Construction South Africa), which recently incorporated the Institute of Timber Frame Builders (ITFB): enquiries@itc-sa.org or (011) 974-1061 • The South African Wood Preservers Association (SAWPA): sawpa@global.co.za

SAFETY AND CAUTION It is important to have options for peace of mind once your plans finally come to fruition. “We charge a fee to manage and oversee the contractors who install the decking, to make sure it is exactly what the designer had planned.

Problems may occur while building the deck, like hitting a sub-surface boulder. The designer has to be flexible and work with the contractor to find a way around the problem,” Herbst concludes.

TREES, SUN, SHADE AND SUCH...

Depending on the tree species, certain root structures may make it difficult to dig the appropriate area for a deck. As an alternative, because it visually links the garden with the deck as a whole, Herbst strongly recommends accommodating existing trees in a garden by building the deck around them where possible. In her words, “Big trees are the skeleton of a garden, so this is advisable.” (But then you must remember to make allowance for the trees’ stems to thicken in diameter.)

In a climatic region like the Cape, you’re in luck if your deck can be blended in with deciduous trees (those that shed their leaves annually), because the deck will get more sun in the winter instead of being shaded and wet. In summer the deck will be more shaded and protected. Sometimes the seasonal sun- and shade exposure can be problematic for other reasons, as Herbst explains, “If you are planning any planting and the deck is elevated, the shade might be a problem if your plant selection requires sun.”

FEBRUARY / MARCH 2015 //

Regardless of the intended purpose of a deck, whether for leisurely braais or as a commercial boardwalk, it must be safe to use and therefore has to adhere to all applicable public safety regulations. It is important to note that the governing National Building Regulations are strict and comprehensive, and although Timber iQ has reported on these in a previous issue, they are not repeated in this article. Please contact your local authority before commencing with any plans or installation of a deck, to be certain that you comply with any requisite plans, building permissions, and safety aspects.

ABOUT THE GREEN ZONE Stephen Hetherington with The Green Zone designed the deck that received the Bronze Award at the 2013 Institute of Timber Frame Builders (ITFB) award ceremony. In 2014, The Green Zone was further recognised by the South African Landscapers Institute (SALI) with a Gold SALI Award for Landscape and Turf Maintenance and a Silver SALI Award for Landscape Construction with in-house design.

Jiri Oslizlo, Agrop/Novatop

Roger Kuratle opened the conference by welcoming the delegates, speakers and sponsors.

Jiri Oslizlo of Agrop/Novatop followed suit and spoke about the progress and experience of the Novatop system in South Africa as applied to the company’s experimental House Pinotage, built in Bellville, Cape Town. Advantages of the build include easy and fast assembly, accuracy and workability of the components, its vapour-permeability, its dimensional stability, eco-friendliness, the pleasant microclimate it creates, and its visual and tactile aesthetics.

Hannu Garny Hannu Garny, Master of Ceremonies, originally from Namibia and now residing in Cape Town, led the event with his South African charm and expertise.

Bernadette Hunkeler Brown, Swiss Consul General of Cape Town This was followed by the welcome address by the Swiss Consul General of Cape Town, Mrs. Bernadette Hunkeler Brown, who playfully challenged the event’s theme by emphasising the deep, ancient history of using timber to create everyday objects. She continued to remark on the material’s very modern appeal in construction, being a green sector driver for economies, and a potentially sustainable material for all applications. She praised George Kuratle and his team for their perseverance and success in this growing interest group.

The project was initiated as a means to bring innovative solutions to the South African market, to build on the Novatop brand in a local context, and to familiarise the local market with the Novatop brand. Ian Fuller Agencies have since 2014 taken up distributorship of the product.

The Novatop product is Eco Certified and the company is in the process of obtaining its Agrément certification. Oslizlo also pointed to Novatop’s new Hout Bay project, which is also to be built using the Novatop product.

Alayne Reesberg, CEO World Design Capital Alayne Reesberg, CEO of Cape Town for World Design Capital 2014 – a fantastic opportunity for Cape Town, and indeed, South Africa to showcase to its own people and the world its design capabilities, not only in terms of only objects, but of impactful working systems and processes – highlighted the various components of the initiative, drawing on specific projects as examples, and also touching on developments and offshoots of the initiative post-2014.

FASTENING SYSTEMS

The origin of Gang-Nail® which changed the way modern timber roof trusses are made The Gang-Nail® timber truss connector plate started a whole new way of mass production of pre-fabricated roof structures and set the course of MiTek® Industries worldwide.

14 Gauge

18 Gauge

20 Gauge

THE NAIL-PLATE It all started in 1955 when Carl Jureit (the founder of Gang-Nail Inc., later to become MiTek Industries and part of Warren Buffet’s Berkshire Hathaway group of companies) invented and patented the Gang-Nail connector plate.

With a basic strength of about 21kg per pair of protruding nails from the Gang-Nail plate, this ensured that this new timber truss connection system was approximately four times stronger than conventionally nailed trusses.

Gang-Nail impact press for the manufacture of special and standard trusses in smaller centres

EARLY TRUSS MANUFACTURING EQUIPMENT In conjunction with some early truss manufacturing equipment like the Gang-Nail ‘Drop-Hammer’ or even the Hydro-Air ‘Mono-Press C-clamp’, the ever-growing demand for new roof structures in a booming post-war USA market could be easily met and as such, set the standard throughout the world for pre-fabricated nail-plated timber roof trusses.

The improved strength of the Gang-Nail plated trusses was evidenced in 1992 when Hurricane Andrew destroyed many homes in South Florida.

Homes built with Gang-Nail plated trusses were far more likely to survive than those whose trusses had been toe-nailed.

EARLY DESIGN AIDS AND SOFTWARE:

EARLY TRUSS TESTING

For quite some time, until the advent of the personal computer in the mid ‘80s , designs were often done in accordance with system-provided ‘Span Tables’ and TPI (Truss Plate Institute) guidelines, or for more complex structures, the system engineers would do the required calculations using main-frame computers, often the size of a small room.

In 1965 when the Gang-Nail concept was introduced to South Africa, no local official nail-plate values were available. So these had to be derived utilizing local timber and Gang-Nail plates in a full size testing procedure which was then a very manual process.

MITEK INDUSTRIES TODAY Technology has certainly advanced tremendously since 1965. However, one aspect has remained consistent: MiTek continues to create the advantage by providing the latest technological roofing solutions, software and equipment to the local roof component industry.

MiTek Industries South Africa (Pty) Ltd. is proud to have served the local South African market for the past 50 years and looks ahead to an even brighter future of creating the advantage for the roofing industry.

FIRE RETARDANTS

Fire safety and timber construction Local companies partner to develop dual-purpose fire retardant and biological preservative treatment.

O

ver the past 60 years or so the use of wood in the construction industry has generally been limited to light timber frame construction, cladding, theme parks, and trusses. During this time, steel, concrete, and glass became the fundamental components in the building material mix and timber as a structural element of design and construction fell largely out of favour.

FEBRUARY / MARCH 2015 //

One of the main reasons for the decline of the large-scale use of timber was the misconception surrounding fire and timber, and even building codes prohibited timber buildings in urban areas.

Fortunately, that is all changing. Timber-based construction is becoming increasingly popular and massive amounts of time, money and energy are being spent investigating new methods and models for its use.

FIRE RETARDANTS

FLAMBOR FR treated timber trusses at Steyn City Equestrian Centre.

There are even plans for a 42-storey skyscraper built in prefabricated sections adding to the existing, 9- and 10-storey buildings in the UK and Australia.

It is a little known fact that timber has an inherent resistance to fire. Wood burns slowly at approximately 0.6mm per minute (0.02 inches per minute). The char created on the wood surface as it burns helps protect and insulate the unburnt wood below the charred layer. The unburnt portion of a thick member retains 85 to 90 percent of its strength. Hence, a wood member with a large crosssection can burn for a significant period of time before its size is reduced to the point where it can no longer carry its assigned loads. The use of an effective fire retardant will enhance the charring of the timber when exposed to fire, ensuring a more stable charred layer to protect the unexposed timber, with the resulting effect of using smaller structural timber members.

Fire retardants are available; however, the process of effective treatment to ensure correct treatment levels of timber can be somewhat complex. Micon and Timberlife have developed FLAMBOR FR, a dual-purpose fire retardant and biological preservative treatment, to meet the increased demand for fire retardant timber to the construction and design industries.

FLAMBOR FR is unique in its formulation as it is a combination of boron-based wood preservative (TOPRO 94) and phosphate-based fire retardant (FYRCON) treatment available for all H2 applications, as well as exterior applications with no ground contact (Class H3), provided a suitable water repellent sealer is applied.

Research is currently being done to get immediate classification of H3 without needing to apply the water repellent surface coating after treatment.

FLAMBOR FR has been used on several prestigious projects throughout southern Africa and abroad and is in the process of being registered and approved for use in Australia.

FLAMBOR FR BENEFITS: • A timber frame panel wall was tested in accordance with SANS 10177, Part 2 (equivalent to BS 476-21) and achieved a Fire Resistance Rating (FRR) of 30 minutes – CSIR Contract Report – No. BF 502/063 5600 5664.

• Meets wood preservative requirements in terms of SANS 10005, 1288 and 457.

• The boron-based active ingredients used in the manufacture of TOPRO 94 are the only wood preservative compounds capable of also penetrating the impermeable heartwood portion in difficult-to-treat timbers via the diffusion process. All other commercially available wood preservatives can only penetrate the permeable sapwood portion of timber during pressure impregnation, leaving the heartwood portion untreated and therefore unprotected against biological attack.

• Environmentally friendly/acceptable.

• Utilises standard pressure impregnation processes and treatment facilities.

• One-step treatment process does not alter the natural colour of the wood.

• Simple on-site quality control procedures.

• Quality assurance of treatment by SABS. • Treated timber compatible with most wood stains and paints.

• Savings on insurance premiums of structures treated with FLAMBOR FR. • No health risks associated with chemicals used in the treatment process.

• Longer lifespan of treated structures.

FLAMBOR FR is pressure impregnated into the timber structure, and the chemical composition allows for easier penetration of the active ingredients into the wood.

Lower impregnation pressures and faster production turnaround times are therefore possible without sacrificing penetration and retention requirements.

FIRE RETARDANTS

The timber frame building system in South Africa, covered by SANS 10082, is included in the National Building Regulations (NBRs), and is recognized by the National Home Builders Registration Council (NHBRC), as well as lending institutions, insurers and local authorities.

In terms of the fire safety requirements contained in the National Building Regulations (NBRs) SANS 10400-T, a safety distance of 4.5 metres is required when combustible materials such as timber external walls and thatched roofs are used, and 9 metres between buildings on the same premises. The external walls must also have a minimum fire resistance of 30 minutes when tested in accordance with SANS 10177-2.

Recent fire tests performed at FIRELAB on timber treated with FLAMBOR FR in accordance with SANS 10177-10 and the comparative corner tests showed that no surface spread of flame was observed on the test specimens. The testing also revealed that all flaming and glowing of the FLAMBOR FR-treated timber directly exposed to the respective ignition sources stopped when the ignition sources were consumed. The resulting effect from these tests is that no fire propagation outside the fire exposed areas was demonstrated and therefore the effect of radiation from a treated structure to any adjacent structures would be minimal, hence the consideration for the reduction in safety distances.

Compliance with the NBRs with regard to fire resistance and the fact that the treated timber does not burn or propagate fire outside the exposed area, means that the radiation will only result from the fire source, therefore the safety distances for the respective buildings would be based on the total window areas as for any conventional building (brick and mortar).

FIRELAB comparative corner tests on treated and untreated panels: A – untreated, B – FLAMBOR FR and C – CCA.

FIRELAB comparative corner tests on treated and untreated panels. Only the FLAMBOR FRtreated panel remained standing.

FLAMBOR FR is perfectly positioned to meet the increased demand for the utilisation of timber in the construction industry as a fast-track, green and safe alternative using sustainable renewable resources. A similar product is also available for the treatment of thatch roofs should it be required for the construction of an all eco-friendly building.

Buildings using FLAMBOR FR-treated timber as a construction material will meet all the fire safety requirements as set out in SANS 10400-T, as well as the preservative requirements specified in SANS 10005, 1288 and 457.

ABOUT MINTROAD SAWMILLS: Helping to bring FLAMBOR FR to market is Mintroad Sawmills of Alrode, Johannesburg. Mintroad Sawmills was established in 1946 and has always been at the forefront of introducing new timber technologies to the local market.

Swartland installs eco-friendly kilns Swartland's installation of four new energy efficient kilns is set to greatly improve the company's already-impressive green credentials as an environmentally responsible stalwart.

FEBRUARY / MARCH 2015 //

NEWS

S

wartland has recently installed four new high-tech kilns that were specially imported from Germany.

The new kilns have greatly increased the amount of timber that can be kiln-dried during any single drying cycle – increasing capacity from 75 cubic metres, to an impressive 400 cubic metres.

The kilns are able to achieve best-in-market energy efficiency through a built-in intelligent energy management system, which is able to allow for small fan adjustments to be made in order to reduce power grid loads during peak periods. Dylan Miller from Swartland explains further: “The additional energy management system allows operators to programme product priorities and considers the energy available from onsite heating plants in order to manage best possible productivity and product quality.”

Each kiln also boasts an eco vent that effectively recycles and reuses the heat that is generated during the drying process. This results in less energy being used, less fuel being burned and an overall reduction in CO2 emissions. In addition, the new kilns are exceptionally water efficient – almost 50% of all the water utilised in the kiln-drying process is recovered from the specialised heat exchange process, and then recycled and reused – saving masses of water over the long term.

Every aspect of these kilns has been created to be as energy efficient as possible – even in their design. To this end, the motors and electronics have been positioned on the outside of each unit to ensure that they are protected from excessive humidity and heat, which serves to increase their longevity. By bettering the kiln’s lifespan, the design also serves to decrease the kiln’s overall carbon footprint and in so doing, improves its green credentials even further.

Compared to other market counterparts, the new kilns use a far gentler drying process in order to produce an end result of timber that boasts vastly improved strength and stability, and reduce defects. Swartland’s flagship hardwood timber, Red Grandis, is dried to an equilibrium moisture content (EMC) of 11%, which is perfectly suited to South Africa’s unique climatic conditions.

Dylan notes that the EMC of Swartland’s selected Red Grandis hardwood improves its overall longevity, as well as its already-impressive rankings as an environmentally friendly building material: “Swartland responsibly sources all its Red Grandis (Eucalyptus) hardwood timber from sustainably managed 100% FSC-approved plantations in Uruguay. Red Grandis is characterised by a warm, uniform colour, and boasts a remarkable level of structurally stability. The timber grows extremely quickly and is ready to be harvested at 60cm in diameter after only 20 years, which ensures a sustainable continuity of supply.”

NEWS

Never one to rest on its laurels, Dylan explains that the company’s investment in the new kilns is a prime example of its ethos of always improving on its commitment to be as environmentally responsible as possible. “Swartland is proud of the way its products and practices reflect its vision to make a positive difference to people and the planet.

At Swartland, we are aware that our own business sustainability is directly linked to the sustainability of the planet Earth, and in particular, to the sustainability of natural resources which forms such an important part of our existence as a company. It is just a matter of time until all organisations make the same realisation.”

A SNAPSHOT OF THE ECOLOGICAL ADVANTAGES OF SWARTLAND'S NEWLY INSTALLED KILNS: • Reduced water usage: Fresh water usage has been reduced due to the collection of condensation that is extracted from the moisture inside the kiln. This is recycled and used to condition the wood.

• Reduced CO2 emissions: Not as much heat is required to dry the wood, and as consequence, the overall CO2 output during the drying process has been reduced.

• Reduced gas and steam: A notable reduction in the creation of exhaust process gas and steam due to more efficient processes being put into place.

• Reduced noise levels: Noise emissions have ben notably reduced thanks to a new fan that is far more efficient, boasting impressively low rotations per minute (RPM).

• Reduced energy consumption: Drying times have been markedly decreased and, as a consequence, there has been a reduction in electricity consumption required for the entire drying process to be successfully achieved.

Wood works Welcome to 'Wood works,' a new series of articles penned in appreciation of the wonders of timber and in testament of how wood works for us - every day, in every way.

Article composition by: Staff writer Celéste Perrin Input and images from Andy Stoker, Rare Woods Editorial review by Stephanie Dyer, Timber Information Services

Purpleheart colour change during installation

A

t the heart of the matter in this first article, lies, well, Purpleheart. This beautiful yet practical and versatile exotic was first brought to our attention by Andy Stoker, branch manager of Rare Woods in Knysna.

Stoker rates Purpleheart tops among popular hardwoods, especially for decking, and readily explains: “We find that it outperforms other popular hardwood decking timbers in durability, hardness, and resistance to weathering. We encounter minimal twisting and warping of the decking pieces, so there is minimal wastage when buying in bulk—a win-win for both us and our customers.”

Rare Woods sources its Purpleheart from Brazil and Bolivia and estimates that overall market imports to South Africa are in the range of about 200m3 per annum. Stoker explains that Purpleheart can yield a lifespan of 25 to 40 years dependent on good initial design and regular maintenance, which makes for a very durable timber.

Further adding to its popularity is the fact that it doesn’t require special handling techniques or storage precautions.

And what about Purpleheart’s distinctive colour? “The initial deep purple colour is disconcerting for some customers, and many people think it’s not its natural colour – that the wood has been stained.”

“But on exposure to light it quickly turns to deep purple-brown while being installed. This brown can either be preserved by applying a deck sealer, or it can be left to weather to grey, which is popular here along the Knysna coast,” Stoker comments. As for preservative treatment, he adds that the colour change process can be slowed by using a UV-inhibiting finish.

Being a hardwood, the timber cannot be pressure treated like pine, but due to its natural durability this is not necessary.

We asked whether Purpleheart is a good choice for applications other than decking: “Yes, it is outstanding for use in outdoor furniture, structural applications such as pergolas, and also flooring. It is also excellent for balustrades and hand rails and makes very attractive cladding and screens.” Rare Woods offers kiln-dried Purpleheart for boardwalk and patio decking in widths of 90mm and 145mm (both reeded and unreeded), for beautiful hardwearing flooring, and also as rough-sawn structural posts and beams.

And customer feedback remains very positive, Stoker concludes, “Although the initial bright colour can be quite alarming at first, once in use we have heard nothing but praise and satisfaction for the product. We get many favourable comments about Purpleheart’s durability, strength and hardness.”

TIMBER PROFILE

HERE IS SOME ADDITIONAL INFORMATION ON THE PROPERTIES OF PURPLEHEART FOR THE WOOD ENTHUSIAST:

PURPLEHEART: HARD FACTS Botanical/Scientific name:

Peltogyne pubescens (Family: Leguminosae)

Trade name:

Purpleheart (Other names: Amaranth, Pao roxo, Violet wood, Morado)

Origin: Conservation status: Bole characteristics:

Central America and tropical South America, including Mexico and Brazil, as well as the Amazon basin and the Guianas Not endangered/protected Tall, slender and straight cylindrical boles 15m or more in length and ranging between 0.4 – 0.9m in diameter Dull-brown when freshly cut, but heartwood quickly turns a distinctive purple upon exposure.

Colour:

Further exposure leads to a medium-to-deep brown or purple-brown hue. The sapwood colour is white to greyish-brown.

Grain pattern:

Pronounced: Straight, interlocked or occasionally wavy

Density:

The density ranges from 800 to 1120 kg/m3 (50-70 lb/ft.3) with the average for commercial timber being about 880 kg/m3 (55 lb/ft.3)

Strength/Bending properties:

Hard, heavy and tough. Moderately good steam bending properties.

Seasoning:

Seasons well with little degrade. Dries fairly rapidly but it is difficult to remove moisture from the centres of boards more than 50mm in thickness. FPRL kiln schedule G is recommended. Once dry, movement in service is small.

Durability and preservative treatment:

Highly resistant to wood-destroying fungi and has a good reputation for resistance to dry-wood termites. Only the sapwood is permeable.

Working and finishing properties:

High bending, stiffness and crushing strength. It is rather difficult to work, offering a fair amount of resistance to cutting in most machining operations (due to its high density and because of gum exudation) and it has a severe blunting effect on tools. Pre-boring for nails and screws is required, as it is difficult to nail. Stains and waxes well. Straight-grained material finishes well but tearing occurs in planing and moulding when the grain is interlocked or wavy and a 15° angle is needed to give a smooth finish. Spirit finishes remove the purple colour, while lacquer finishes preserve it.

Applications and use:

Purpleheart is suitable for furniture, boat building, decking and flooring. It is popular for woodturning and detailing in cabinet work, and used for vats, archery bows and tool handles.

Because of its outstanding strength and lasting qualities, and the large dimensions available, it is suitable for heavy construction such as bridges and dock/harbour work.

TECHNOLOGY

Use of drones in forestry Sustainable management from the air

Aerial images have been used in forestry for decades to perform a variety of tasks, such as forest inventories or mapping damage after disasters. Today, very small unmanned aircraft that can fly autonomously - known as drones - can be employed.

U

sing drones to capture image data enables operations to be planned flexibly and at short notice, thus ensuring that image products are quickly available. Thanks to their low flight altitude, drones can even fly under heavy cloud. Moreover, their quiet and energy efficient electric motors are not only environmentally friendly but also reduce the impact of noise on humans and animals. Equipped with a high resolution camera or sensors, drones bridge the gap between arduous field surveys on the ground and costly bird’s eye view surveys carried out by manned helicopters or aeroplanes. Their growing success is helped by the fact that the industry’s solutions are becoming more costeffective and the performance of the flying robots is constantly improving.

Like helicopters, multicopters can take off and land vertically. They are controlled from the ground by a laptop.

With built-in GPS, they are able to maintain their position and altitude or fly to GPS locations autonomously.

44

FEBRUARY / MARCH 2015 //

Depending on the design and weight of the multicopter, the latest models can fly for up to an hour. The camera is capable of swivelling 360 degrees. Thanks to intelligent suspension and flight control, its position is maintained automatically even in windy conditions and a high level of image stability is achieved. The digital images sent live by the multicopter can be ‘georeferenced’, which means that they can be precisely aligned with existing geographical coordinates.

This enables the exact location of any objects photographed to be determined. 3D surface models do not pose a problem either. A number of manufacturers produce video glasses that enable the operator to also ‘take to the air’. While the drone flies over an object using GPS or sight, the video glasses allow the live image from the camera to be viewed in real time. The altitude, perspective and display detail can be changed remotely.

TECHNOLOGY

Using unmanned aerial platforms enables inventories and surveys to be made of forest land with a hitherto unknown degree of accuracy and significantly extended scope. Their low flight altitude and high degree of independence from weather conditions play a key role here. In addition, results from the flight can be directly incorporated into operational planning.

FEEL WOOD FEEL GOOD FEEL SPRUCE

One major application for drones is the mapping of forests and open fields. The images provided can be used in a timely manner for a wide variety of analyses and applications, such as a health check for plants and trees. This includes the early detection and assessment of pest infestation as well as the determination of moisture levels or the extent of dead wood. The condition of tree crowns, which could previously only be evaluated after a great deal of time and effort, can now be documented by drones in razor-sharp images within just a few minutes. The analysis of water, snow, hail, storm and fire damage is another area in which drones are set to play an increasingly important role in future. Last but not least, the ‘eye’ of the drone is able to quickly and easily locate the position and extent of damage caused by wildlife.

The combination of infrared images and NDVI (normalized difference vegetation index) photos produces images that can be used to measure plant growth, the extent of vegetation and the production of biomass. The simple capturing of forestry conditions also enables reforestation projects to be planned in detail, precisely defining how many plants should be planted in which location and how densely. In the mountains, on the other hand, the construction of skid trails or cableways often presents a major problem.

From the bottom of the mountain, it is difficult to judge whether a rock, steep drop or protected tree is in the way. The drone immediately provides a clear result, facilitating rapid decision-making. Unlike conventional image aircraft which can only look down vertically, the drone’s camera can also be tilted, allowing slopes to be recorded precisely. Another increasingly important field of application for multicopters is the observation of climate change. This is an area where forestry can make a key contribution – backed up by digital material – to political decision-making.

According to a study conducted by the McKinsey Global Institute in May 2013, drones – as part of robotics – are already influencing important economic factors, such as labour costs, productivity, flexibility and safety. Its efficiency, cost-effectiveness and ease of use open up major future potential for the multicopter. Powered by an environment-friendly electric motor, which results in low noise levels and low emissions, multicopters are an innovation that is perfectly in line with the requirements of contemporary technology. The topic will also be presented at LIGNA 2015 on an open-air demo site run by the German Forestry Council (KWF).

TIMBER CONSTRUCTION

Building with timber Meeting the requirements Supplied by the Institute for Timber Construction South Africa

W

hen specifying for timber construction, it is necessary to make a thorough study in relation to specific designs, site conditions and the National Building Regulations, among other things. Timber quality is equally important in the determination of a project’s success.

In South Africa, under the Building Standards Act (Act 103/1977 as amended), and the National Building Regulations, there are only three legal methods by which to design and construct timber structures: 1. Roof trusses manufactured in accordance with PART L Roofs of SANS 10400 – The Application of the National Building Regulations. This standard outlines the ‘deemed to satisfy’ requirements for nailed and bolted trusses and specifies timber sizes along with the number of nails and bolts, as well as the accepted truss shape.

2. Timber framed structures built in accordance with SANS 10082 – Code of Practice for Timber Buildings.

This code of practice outlines the ‘deemed to satisfy’ requirements for the design and construction of timber framed structures.

3. By engaging the services of a professional engineer (as required in PART B of the National Building Regulations) who would work in strict accordance with SANS 10160 Loading Code and SANS 10163 The Structural Use of Timber.

Approval has, in general, been given by municipalities to pre-fabricated truss fabricators who use a suite of rational design programs supplied by system suppliers to design roofs up to 10m in span for non-public buildings. All of these system suppliers have been accredited and approved by the Institute for Timber Construction South Africa (ITCSA).

Timber framed structures in compliance with SANS 10082 are deemed to satisfy the National Building Regulations and in compliance with SANS 10400, which cover conventional construction methods and processes. Only deviations from the specified design and construction requirement of SANS 10082 will demand engineering intervention and the provision of a rational design.

All larger buildings and those to whom the public has access are to be designed under the supervision of

46

FEBRUARY / MARCH 2015 //

professional engineers applying rational design criteria to satisfy engineering first principals. Engineers who have access to engineering design software can use these design programs to satisfy the rational design requirements. Timber structures designed by a competent person in accordance with PART B of the National Building Regulations are not limited to the size, height, span, pitch and geometric configuration of structures as specified in SANS 10082 or PART L of SANS 10400.

The ITC-SA works closely with the technical committees of the South African Bureau of Standards (SABS) on grading and treatment specifications for structural timber, including design codes and standards for structural timber, as well as on matters affecting the National Building Regulations and their application.

This ITC-SA has instituted a Certificate of Competence scheme for timber frame builders and truss fabricators who design, manufacture and supply inter alia prefabricated nail-plated trusses. Stringent auditing of the both professions’ operations and key personnel are done before the awarding of such Certificates of Competence.

This is an assurance of quality on timber structures for both the specifier and general public.

TIMBER QUALITY All timber used in a structural application should be structural timber which complies with the requirements of SANS 1783-2/1707-1/1460/10149, and bears the full standardisation mark. Timber used for roof battens should comply with SANS 1783-4/1707-2, and should also bear the full standardisation mark.

Timber used for the construction of timber structures on site must be ordered in the dimensions in which it will be used and should not be re-sawn into smaller crosssectional sizes on site, as this will cause the grade, strength and dimensional tolerances to change.

TIMBER SPECIFICATION The various grades of timber are defined by different strength properties and allowable design stresses. The grades commercially available are: S5, S7 and S10 (note: there is a limited availability of grades S7 and S10).

TIMBER TREATMENT In certain magisterial districts in South Africa, it is illegal to use timber which has not been treated against biological attack for structural purposes.

Treatment can be completed using either CCA or Boron in accordance with SANS 10005 Treatment of Timber.

STORAGE OF TIMBER Structural timber stored on site should be stacked on level ground on bearers and adequately protected against the weather by covering with a waterproof material. Air must be allowed to circulate through the timber stacks, and strapping around bundles of battens should not be removed until the battens are to be fixed in order to prevent excessive warping of the battens.

HOUD IS GOUD MAKING WOOD GOOD SINCE 1980.

FASTENING SYSTEMS

Do it once. Do it right.

SPAX screws, distributed to the South African market by Faitsch Products/Fixtec Fasteners, offer optimal fastening solutions for roofing applications.

I

n 1967, Altenloh, Brinck & Co Company introduced the SPA X self-tapping screw for use in timber with, for the time being, the new Pozi cross recess, into the market.

The most common screws were those with countersunk head and with full thread for screws in lengths of up to nearly 70mm respectively with partial thread for screws in lengths longer than 70mm.

In the following years, self-tapping screws substituted lag screws for several reasons, mainly because self-tapping screws are quick and easy to use and the installed connection in total is more cost efficient. Furthermore, self-tapping screws have a defined strength and higher load-bearing capacity. Today a variety of self-tapping screws are available on the market, including different head shapes for different applications.

48

FEBRUARY / MARCH 2015 //

For standard applications in timber design and building, screws in lengths of up to 800mm, with either partial thread or full thread, with outer thread diameter as far as 12mm, and for special applications up to 14mm outer thread diameter, are used.

Strength properties and standards for design and installation, which are unique for the respective screw in use, are also stated in the European Technical Approval (ETA).

General information regarding the design of self-tapping screws and load-bearing charts, based on the European Standard for Designing Timber Structures Eurocode 5 (EC5) and the respective SPAX European Technical Approval (ETA), can be found in the SPAX design guide which is available from Faitsch Products/Fixtec Fasteners.

FASTENING SYSTEMS

The main head shape designs are countersunk head and washer head. Countersunk head is a universal multipurpose head shape for timber-to-timber and steel-to-timber connections.

It countersinks itself flash into timber and fits nicely and neatly into pre-drilled and countersunk steel plates. The use of washer head is mainly for timber-to-timber connections and is able to create high clamping forces to hold the building parts in position with high force.

Partial threaded screws are able to tighten building parts together and are even better in combination with washer head. The shank of the partial threaded part should be a minimum length of the thickness of the building part, which is to be attached. Common applications for washer head screws are rafter-to-plate connections or the connection of pre-fabricated wall panels to each other, and due to the head shape design, washer head screws are able to transfer higher pull-out values in comparison to lag screws. Therefore, washer head screws are perfectly applicable to tighten building parts together.

Cylindrical heads are in use only for full threaded screws or for screws with fixing thread, such as SPA X decking screws. Full threaded screws are unable to tighten building parts together.

The main benefit of full threaded screws is the capability of high tensile load-bearing capacity, limited only by the screw strength itself. For building and design with timber this is a very important load-bearing behaviour. It is therefore possible to reinforce timber building parts, such as notched beam support, with full threaded screws.

The reinforcement prevents the notched timber from splitting due to stress perpendicular to the grain in the early stages of loading and increases the load-bearing capacity of the beam by far.

Furthermore, inclined driven-home full threaded screws are in use to connect a brace to a post and a plate or to connect a plate to a post quickly and easily. By carrying out a connection in this way, sheet metal connectors or big bolted joints can be avoided and the screwed connection can be completed to appear almost invisible.

SPA X screws have different point designs, such as 4CUT or CUT. Both point designs improve processing and reduce splitting of timber, also driving home torque. Even so, the self-tapping screws can be driven home without pre-drilling, and depending on the timber used, pre-drilling is recommended and required.

FASTENING SYSTEMS

Driving home a screw is the most demanding process in a screw’s life, and once it is driven home, bearing loads are less demanding. Hardwood timber with a characteristic density of more than 500kg/m³ shall be pre-drilled properly to the full length. By pre-drilling the timber, unexpected damage to the screw can be prevented.

In timber design and building, for example, for rafters with 40mm to 60mm width, washer head screws with 6mm outer thread diameter should be used. For rafters from about 50mm in width or wider, washer head screws with 8mm outer thread diameter are most common.

Screws made of carbon steel need corrosion protection.

The yellow zinc passivation, a galvanic zinc plating, is the most common corrosion protection. WIROX is a SPA Xdeveloped galvanic plating, providing higher corrosion resistance and increased environmental acceptance compared to the yellow zinc passivation.

The best possible corrosion resistance is provided by the use of appropriate stainless steel screws. In Europe today the main stainless steel in use is 304 (A2) and for higher corrosion resistance 316 (A4) is used.

Pressure Treated Timber Timber with a moisture content below 20% cannot rot. This may not always be possible when used outside in exposed conditions as it requires proper application and maintenance of a suitable penetrating and water repellent wood sealer.

The options are to use either naturally durable but expensive exotic hardwoods, or less costly locally grown non-durable Pine or Eucalyptus (gum) timber or poles, that have been pressure treated with a suitable wood preservative to the desired exposure or hazard class.

The H class system is a guide to help you buy the correctly treated timber for your project.

Be sure to look for the required H class on the timber as well as one of the two quality marks given below.

Sustainable Timber Resource Timber is the most sustainable building product available to man. It’s naturally renewable. Over 90% of plantations grown in South Africa are FSC® certified.

Hazard classes: H2— dry interior above ground H3— exterior above ground H4— in ground contact H5— in contact with fresh water and wet soil H6— in contact with marine waters

Lonza Wood Protection

rebrands as Arch Wood Protection Following a strategic review of the South African market, an innovative rebranding strategy has been introduced to dispel any confusion as to the identity of the Lonza wood businesses.

D

oug Sayce, General Manager of Arch Wood Protection South Africa, explained that when Lonza purchased the global Arch business in 2011, the company names of the various wood protection businesses remained unchanged, which created confusion on the South African platform. It was therefore decided that the global operations would be rebranded as Arch Wood Protection from January 2015, and that the South African company name would remain unchanged as Arch Wood Protection (SA) (Pty) Ltd. Sayce added, “This proactive and positive move will help unify all our global wood protection businesses around the world and provide a distinct and consistent focus in our various markets. Our successful customer-focused business remains a key emphasis of the Lonza family and we move forward with Lonza’s continued support to

develop exciting new opportunities, whilst remaining key innovators for our wood protection customers and markets.”

The new Arch Wood Protection brand design is a natural evolution from the original Arch identity during the last decade. This fresh and innovative image is perfectly aligned with the company’s philosophy to provide tried and tested wood protection products, application technologies and customer support services that are designed for real-world environments.

Current service and personnel contacts, as well as all banking details for the business will remain unchanged.

THATCH

Thinking thatch The Thatchers Association of South Africa (TASA) offers insight into the legislation governing the correct construction of thatch roofs.

THE MEASUREMENT OF POLES Some roofs are built with undersized poles and the responsible person is often unaware of this, as they are led to believe a pole is measured on the thick end. Keep in mind the minimum pole diameter that may be used for thatch structures is 100-125mm, as per SANS 10407.

The thick end diameter of the pole varies, but an accepted norm is that the pole tapers by 7.5mm per metre on average.

THATCH LAYER THICKNESS Many thatchers will lay an eave layer that is 200mm thick, then taper the layer to the ridge where the thickness ends up as little as 75mm. It is not obvious once the roof is complete, as all that differs is a slight change of angle on the thatch surface. This is less likely to occur in the case of gable-ended roofs, as the taper is obvious. On completion of the thatching, the thatch layer thickness should be checked randomly over the entire roof surface.

SANS 10407 specifies a minimum layer of 175mm.

RAFTER SPACING SANS 10407 dictates a maximum centre-to-centre spacing of 900mm. Many roofs are built where this maximum is exceeded.

LATH SPACING The spacing of laths is determined by the average length of grass used. SANS 10407 tables the maximum lath spacing for a given grass length. Closer spacing than tabled is acceptable. The more frequently a bundle is stitched to the structure, the more durable the thatch layer.

STITCHING Roofs thatched with grass: Only tarred sisal twine or stainless steel wire are to be used with a maximum spacing of 125mm.

54

FEBRUARY / MARCH 2015 //

Roofs thatched with Cape reed: Usually galvanized wire is used, but if the roof is near the shoreline, stainless steel wire is used. All wire sways are galvanized.

ROOF SLOPE The minimum general roof slope is to be a minimum angle of 45 degrees. Valleys and hips are always approximately 27 degrees flatter than the general roof slope. To increase the longevity of a roof, some thatchers install valley liners.

The minimum roof slope for dormer windows is 35 degrees.

FREE-STANDING ROOFS These roofs are supported by columns. The footings of these columns affect the overall stability of the roof and adequate footings must be specified by an engineer.

Many columns are planted at a depth too shallow and without the necessary concrete footing, the size of which is determined by the roof load and soil conditions.

Concrete footings should not encase the bottom of the pole, as this will accelerate rotting by not allowing drainage.

BAD DESIGN Never allow overlapping thatch surfaces. The drainage water falling from the higher roof onto a lower thatch surface can accelerate rotting on the lower surface as the penetration of water into the layer is deeper and takes longer to dry. In general, the drainage of water from thatch roofs is an important factor in the design of thatch roofs as all drainage areas such as valleys will degrade faster than general roof slopes.

Dubai WoodShow emerges as Middle East's biggest wood and woodworking machinery trade show 10th edition will feature 250 exhibitors from 45 countries from 14-16 April 2015

D

ubai WoodShow (DWS), the region’s premier timber trade fair, has grown in stature to become the biggest wood and woodworking machinery trade show in the Middle East. The next edition, which will be held from 14 to 16 April 2015, is expecting 250 exhibitors from 45 countries.

Josine Heijmans, Exhibition Director of the Dubai WoodShow said, “DWS has become a major platform for the regional and international wood and woodworking industries. An interesting aspect of the next edition will be the ‘try before you buy’ concept which will transform the exhibition floor into practical workshops. We are creating a perfect environment for enabling fruitful interaction between sellers and buyers.”

Heijmans said that the surging AED 8.82 trillion construction activity in the GCC region is driving the wood industry, as the region witnesses unprecedented growth in imports.

Exhibitors of all skill levels will showcase wood carving, turning, scroll work, fine woodworking, gourd art and pyrography at the three-day show.

A number of top woodworking machinery manufacturers, toolmakers, timber providers and traders will hold skillbuilding sessions, allowing visitors to view the production process first hand, with live demonstrations of machinery in operation.

The previous edition of DWS, organised by Strategic Marketing & Exhibitions, attracted 8 349 high quality trade professionals from 95 countries. The participating exhibitors included 500 brands, suppliers and manufacturers representing 40 countries.

DWS will occupy an area of 13 428m2, offering the latest timber products and tools and a chance to learn from leading international experts and woodworking industrial specialists.

Branch out and be the change!

Greenpop launches its Zambia Festival of Action 2015 WHY ZAMBIA? Zambia has one of the highest deforestation rates in the world. After decades of poor land management, slash and burn farming methods, unsustainable logging and treecutting for charcoal, Zambia currently has an estimated deforestation rate of 250 000 to 300 000 hectares per year – that’s twice the size of Houston, Texas.

58

FEBRUARY / MARCH 2015 //

Greenpop has run their annual Zambia Festival of Action in Livingstone since 2012 as a way to draw attention to their ongoing environmental and eco-education project in the area, as well as to bring people together from around the world to share knowledge and work together in a conference-style way.

EVENTS

Through the project and their three annual Festivals of Action, this dynamic social enterprise is making waves across the Zambezi. Their progress over the past 3 years in Zambia includes: 11 176 trees planted, 97 planting days, 24 sustainability workshops, 7 educational wall murals, over 50 handmade solar cookers, over 10 handmade rocket stoves, 74 Tree Tuesday radio shows, 48 school eco days, 5 community farms and reforestation site.

Over 500 passionate planters from Zambia and around the world have joined in the 4 Festivals of Action so far.

“We’re not trying to save Zambia. The issue of deforestation in Zambia is incredibly complex and we do not intend to solve it with this project. Instead, we hope to plant a seed with the people we reach that will inspire people to get active about a sustainable future for ourselves and our planet. People who come to the Greenpop Zambia Festival of Action come to share knowledge, connect, give back and learn a lot themselves to take back to their countries and make small but necessary changes all over the world,” says Greenpop Director Lauren O’Donnell.

“Speaking for the whole community, we have cut down many trees for fuel. We are grateful to Greenpop for encouraging so many people to plant trees. We hope to spread the message to our friends and neighbours.

Planting trees has really helped Livingstone!” says Gilbert Nyambe, Linda Farm School, Livingstone, where 40 trees were planted during an educational workshop at the Festival of Action 2014.

GET ACTIVE! Greenpop has already started gearing up for their Festival of Action 2015 where the organisation will once again host a variety of sustainability workshops for school children, subsistence farmers, and local and international volunteers and will facilitate the planting of thousands more trees – they are aiming for between 3 500 and 4 000 trees in 2015.

Last year their Festival of Action saw people attending workshops on permaculture and food forests, alternative energy, green building methods, and recycling and upcycling.

In 2015, Greenpop aims to grow the workshop element of the event and participants can look forward to a host of interesting topics which they will announce early next year, so keep an eye on their website and Facebook page.

"Being at Greenpop’s Festival of Action was transformative. Being in such a breathtaking setting with such incredible people who all want to make a difference was amazing.” – Cesca – Boston, USA – Festival of action participant in 2013.

EARTH FEST Earth Fest is a rocking party with great live music from around southern Africa – it forms part of the Festival of Action. Participants who are there on the right dates are invited to enjoy some fine African beats on Saturday 11 July in Livingstone! Expect live music acts from all over southern Africa, groovy beats from local DJs, interactive presentations on environmentalism and sustainability and a great vibe.

JOIN THE FESTIVAL OF ACTION 2015 THEY HAVE THESE OPTIONS: • Schools Programme (28 June to 5 July) – after the good feedback Greenpop received after taking three high school groups on the project in 2014, they have decided to launch a special schools week for 13 to 19 year olds who want to get their hands dirty and experience a learning adventure.

• Festival of Action Week 1 (5 July to 12 July) – all ages welcome • Festival of Action Week 2 (12 July to 19 July) – all ages welcome • Festival of Action – Both Weeks (5 July to 19 July)

TREES FOR FEES Something that has worked really well for participants and for Greenpop in the last three years is their innovative Trees for Fees programme. Greenpop developed this to allow people to fundraise for trees through a personal payment portal in order to get the project fees for free (or discounted). Last year they raised 3 205 trees for the project like this – crowdfunding at its best – and over 20 people took part, asking friends and family to gift trees instead of birthdays, event tickets and other occasions.

Says Viv Connell, a past Trees for Fees participant, “It’s quite fun asking people to donate money for trees. One just puts it out there and waits. And then you fall in love with the people who actually DO send tree donations.”

ABOUT GREENPOP Greenpop is on a mission to (re)connect people with our planet. They plant trees and have fun doing it. They plant trees in urban greening and reforestation projects and host green events, educational workshops and festivals of action to inspire people to get active about a sustainable future.
