0302 INSULATIONINSIGHT

Staff members from the Pembridge production site had a night to remember at the recent Herefordshire and Worcestershire Chamber of Commerce Business Awards, taking home the prestigious ‘Manufacturer of the Year’ award for 2017.

Over 50 finalists took part in the award evening, competing across 11 categories. The glitzy ceremony featured a ‘Best of British’ theme complete with London Underground decorations, buskers and an Abbey Road photo booth. Further entertainment was provided by stage hypnotist, David Meade.

The judges were particularly impressed with the ongoing success of the Kingspan range of vacuum insulation panel systems, and all the work that has been undertaken launching the new Kingspan Kooltherm® K100 range of products. The Kingspan Kooltherm® K100 insulation boards are now available for a wide range of applications and their industry-leading phenolic core achieves a lambda value of just 0.018 W/m•K across all thicknesses. This makes it simpler for specifiers and contractors to achieve the desired level of thermal performance with a slim build-up.

The hard work of the Pembridge customer service team was also recognised as they were shortlisted

within the ‘Excellence in Customer Service’ category.

In this issue, you can find out how our award-winning manufacturing approaches are benefiting the wider industry, from an introduction to the fabric first construction approach (pg. 16-17), to details on how structural insulated panels are revolutionising project timescales and building performance (pg. 8-9).

PHENOLIC – THE KING OF RIGID THERMOSET INSULATION Where PIR succeeds, phenolic excels, providing enhanced thermal and fire performance with the same benefits of light weight, durability and ease of installation. Recent developments have led to even lower levels of thermal conductivity, with lambda values as low as 0.018 W/m•K. This means that the boards can be slimmer than PIR, and other lower performing materials such as mineral fibre, creating real value in terms of space and energy savings.

VIPS – THE NEXT EVOLUTIONARY STEP Replacing the air in fibrous insulation materials with a different gas in closed cell insulation provides greatly improved performance, but there is still a gas which adds unnecessary conductivity. Removing the air completely to create a vacuum provides outstanding thermal conductivity.

Vacuum Insulation Panels (VIPs) are now available as mainstream products and, with a declared lambda of just 0.007 W/m•K, can rightfully be called next generation insulation materials. They can be used to insulate problem areas that other insulants simply cannot fit, and are helping to move building energy efficiency to a new level, even for difficult refurbishment projects.

THE EVOLUTION OF INSULATION

CONDUCTION. CONVECTION. RADIATION. These are the three ways in which heat is transferred: the purpose of insulation is to block that transference. In all three cases, insulation acts as a barrier to heat loss; it is a poor conductor, it retards the impact of convection currents, and it helps to scatter or reflect radiated heat.

To reduce conduction, most insulation works by having a greater proportion of void than it does of solid material, and ensuring that solid heat flow paths are long and tortuous. The gasses between the solid materials can also conduct heat, but some gases (such as the air contained by open cell fibrous materials) will conduct more heat than others (such as the blowing agents used in high and premium performance closed cell insulants).

With convection, open cell fibrous materials rely on the diffusing effect of the fibrous matrix to limit the convective

heat transfer through the joined up pockets of air. Closed cell insulants rely on a more effective strategy: the fact that the cells within the materials are not connected, all but kills off the effects of convection.

For radiation, there are two effects to consider. Firstly, the complicated matrices of most insulation materials will tend to scatter radiation, reducing its impact. The second consideration is that some insulation materials come with foil facings which limit the amount of radiative heat than can be absorbed into the insulant or emitted from it, should the product be installed next to an air-space.

Clearly the different types of insulation work in different ways, so how does this affect specification? Many sources refer to needing a certain thickness of insulation to meet the requirements. However, the vast range of insulation materials on the market not only have very different characteristics, they also have different benefits and, most significantly, levels of performance. This means that different thicknesses of each material are needed to achieve the same effect. What’s more, the difference can be very significant in terms of space needed and weight to support.

The lambda value of the product will tell you how thermally effective it is. Lambda is a measurement of how easily heat travels through the insulation; the lower the lambda value, the more difficult it is for heat to pass through, therefore the better the thermal performance and the less thickness is needed to achieve the U-value you want for the construction.

GOOD. BETTER. BEST. All of Kingspan’s products are on the high end of the performance scale, but even within the product ranges some are more efficient than others.

PIR – THE EVERYDAY HERO Polyisocyanurate, or PIR, insulation is one of the most commonly used rigid insulation boards. Light and durable, it is frequently used for flat roof constructions where weight and compressive strength can be an issue. Kingspan Insulation’s foil faced products have a thermal conductivity of 0.022 W/m•K.

We tend to think of insulating our buildings as a modern invention, driven by Building Regulations and the need to conserve energy. The truth is that the principles have been around for a very long time. The Ancient Egyptians used thermal mass to keep buildings cool in the heat of the desert sun, and to store warmth against the freezing temperatures at night. The Romans used to wrap hot water pipes with cork to make sure their baths stayed steaming, while Vikings may have been the pioneers of airtightness, using mud to prevent draughty gaps.

However, it is only in recent decades that insulation as an essential construction product has really taken off, sparking the development of ever more efficient materials to suit every kind of application. So, how does insulation work, and what is the difference between the various types of insulation materials that are on the market today?

A NEVER ENDING STORY With the growing demand for energy conservation and the imperative to cut carbon emissions, the performance of insulation materials will no doubt continue to evolve, providing thinner solutions that will deliver energy savings over the lives of our buildings.

PRODUCT:Kingspan TEK® Building System

(142 mm)

LOCATION:Swavesey, South Cambridgeshire

Designed by Lyster Grillet & Harding, the new facilities needed to be completed to a tight deadline, without encroaching too far onto the school’s courtyard space. The solution was the Kingspan TEK® Building System, installed by Kingspan TEK® Delivery Partners – Lowfield Timber Frames. Simon Brown, Associate Director at Lyster Grillet & Harding, explains:

“The project needed to be completed within a short construction programme dictated by the EFA funding programme and the school calendar. We specified the Kingspan TEK® Building System to form the envelope of the classroom block, which enabled a rapid turnaround of design, costing and progression to site, to allow completion of the second phase for Easter 2016.”

The panels arrived onsite pre-cut to the project’s exact specifications. This bespoke approach almost

eradicated onsite alterations and, combined with the panelised system construction, allowed the installation team to establish a fast and predictable installation programme.

In addition to excellent thermal and air permeability performance, the Kingspan TEK® panels also offered additional design benefits, as Simon Brown explains:

“Our experience of designing projects using the Kingspan TEK® panels from the outset allows us to exploit the inherent flexibility of the system, greatly simplifying the incorporation of clerestory windows, adding drama to the corridors in addition to, on a practical level, daylight and natural ventilation strategies without compromising the buildings’ performance.”

PANELS ARE PRIME PLAYERS FOR PASSIVHAUS

Founded in Germany in the early 1990s, Passivhaus is now globally recognised as the benchmark certification in fabric-first design. To meet the standard, the building must achieve a number of demanding performance requirements, including limiting specific heating demand to 15 kWh/m2/year. Each construction element must have a U-value lower than 0.15 W/m2•K, so the choice of insulation plays a major role, and careful attention also needs to be paid to the reduction of thermal bridging.

Meeting these requirements with conventional brick and block construction methods can be challenging and costly. Modern methods of construction, such as Structural Insulated Panels (SIPs), offer a well-established alternative, providing inherently excellent fabric performance and airtightness, with a simple, streamlined construction programme. Even more importantly, SIPs make it possible to build to this kind of standard without the need for excessively thick walls, and with complete design flexibility, whether the homeowner’s tastes run to the ultra-modern or a more traditional appearance.

Our Kingspan TEK® Building System of SIPs feature two OSB/3 (Oriented Strand Board) facings either side of a rigid thermoset insulation core. We offer the system panels in two thicknesses – 142 mm and 172 mm – which can achieve respective U-values of 0.20 W/m2•K and 0.17 W/m2•K, and can be used to form the walls and roof of a property. With an additional layer of insulation, such as Kingspan Kooltherm® K112 Framing Board, this performance can easily be raised to meet the demanding thermal performance requirements of the Passivhaus standard.

As well as providing excellent levels of insulation, the jointing arrangements inherent in SIPs can provide extremely airtight structures. Kingspan TEK® Building System constructions can achieve air-leakage rates as good as 1 m3/hour/m2 at 50 Pa. Once airtight tape is applied to junctions, this rate can be reduced even further to the 0.6 air changes per hour @ 50 Pa required by the Passivhaus standard.

SIPs can also help to avoid problems which may be associated with other common construction techniques such as air-leakage through poorly sealed sockets or switches, at floor zones through masonry cavity walls, under skirting boards and

through poorly sealed loft hatches and top-storey ceiling light fittings.

The demanding airtightness requirements of the Passivhaus approach makes mechanical ventilation essential in order to maintain a constant flow of fresh air within a property. MVHR units use the heat from outgoing stale air to warm incoming fresh air, further reducing the property’s heating demand and creating a fresh and comfortable indoor environment.

The jointing arrangements in SIPs mean that the insulation layer is typically interrupted by less repeating studwork than in a timber frame, greatly reducing repeating thermal bridging. Their factory-engineered design ensures very low levels of linear thermal bridging at junctions and openings.

Once onsite, SIPs can usually be fitted with virtually no adjustments, providing a highly predictable, dry build programme which can typically be completed within a matter of weeks. Once the shell of the building is erected and a breather membrane is applied to the outer face of the SIPs, the property is weather tight and internal fit out work can begin, reducing programme length and costs.

to span further without additional support. Not only did the thicker panels help to preserve the open modern aesthetic of the show home, installing them in a large format also simplified the build and reduced the time spent working at height.

“We purposely selected the design which would be the most complex to build from an energy efficiency perspective as it offered the most flexible family home”, architect and Head of Sustainable Future, Rory Bergin, explained. “The result is a testament to the high levels of building performance and architectural design that can be achieved with careful planning, expert workmanship, and the right products.”

As part of the meticulous planned construction programme, Kingspan Potton were determined not only to meet the airtightness requirements within the Passivhaus Standard, but to achieve an air leakage rate far below them.

“We have used the Kingspan TEK® Building System on hundreds of low-energy buildings and trust and understand its

performance characteristics”, Dr. Paul Newman, Director of Self-Build at Potton, said. “From experience, we knew that by carefully sealing and taping the external wall junctions that we could achieve the airtightness required for a Passivhaus level construction. After carrying out two tests, including a smoke test to reveal leaks, we attained a final result of 0.43 ach (air changes per hour) @ 50 pa, exceeding the standard’s minimum of 0.60 ach @ 50 Pa.”

ENERGY EFFICIENT ENVELOPES

In the years since its inception, buildings of all shapes and sizes have been constructed to the rigorous requirements of the Passivhaus Standard, providing a clear illustration of the benefits of a fabric-first construction approach. Many of these projects have benefited from the inherent advantages of SIPs, delivering both thermal performance and airtightness with a fast-track construction and without requiring architects to compromise on design quality.

CERTIFIABLY SUPERIOR

Kingspan TEK® Delivery Partners, Kingspan Potton, took advantage of these benefits on their new show house in St Neots.

HTA Design’s blueprint for the new Elsworth Show Home centres around a small enclosed courtyard with a large rooflight to maximise incoming natural light. This is surrounded by the staircase and living areas, whose size and purpose can be adapted to suit different lifestyles.

The project team were determined to produce a design which demonstrated the potential of Passivhaus buildings, dispelling the myth that aesthetic sacrifices are required when creating a highly energy efficient building. To accomplish this, 142 mm Kingspan TEK® Building System panels were used to form the external walls of the building. An additional external layer of 100 mm Kingspan Kooltherm® K12 Framing Board was then fitted to ensure a ‘thermal-bridge free construction’ and to achieve a wall U-value of just 0.10 W/m2∙K.

The roof was constructed with 172 mm Kingspan TEK® Building System panels as the increased thickness allows the panel

VACUUM INSULATION AND UNDERFLOOR HEATING – A SLIMLINE COMBINATION

Underfloor heating (UFH) has been turning up the heat on wall based competition in recent years. The systems now account for around 6.5% of the total UK heating market1 and have continued to grow steadily year-on-year. The compact design of modern UFH systems means they are not only a popular option for new-builds and extensions, but also for retrofits.

In order for the systems to function efficiently, it is important to install an insulation layer beneath the UFH to limit heat loss through the floor. This can prove challenging in solid floor retrofit applications, however, as fitting both UFH and an insulation layer may significantly raise the existing floor level. Fortunately, Vacuum Insulation Panels (VIPs) - such as our Kingspan Flooring System - can now provide a space-saving solution, allowing the desired U-value to be met with a minimal build-up.

WHY UNDERFLOOR HEATING? Perhaps the most obvious advantage of underfloor heating is the ability to clear walls of radiators. This helps owners to declutter rooms, increases usable wall space and provides more flexibility when laying out furniture as there is no need to worry about sofas or chairs blocking the heat from radiators. UFH is a particularly popular choice for properties or rooms with timber, laminate or tiled floors, such as bathrooms and kitchens, which can remain cold underfoot with conventional wall mounted heating.

There are two common types of UFH systems – electric and water. Traditionally, retrofit work has been carried out with electric systems due to their slim profile and relatively low up-front cost. Over the past few years though, slimmer water-based systems have been introduced onto the market. These systems generally operate with much lower temperature water than conventional radiators. As such, whilst the initial purchase costs are typically higher than those for electric alternatives, they can notably reduce energy usage and costs over time. To

maximise this energy saving potential, it is important to ensure an effective insulation layer is fitted below the system.

FLOOR INSULATION On suspended ground floors, this process is relatively simple. A standard rigid insulation board can be installed between the floor joists followed with a polythene sheet separation layer and the UFH can then be fitted above. Rigid insulation boards, such as phenolic insulation, provide a good solution in these applications as these boards can be cut to size with a fine-toothed saw and secured in place with timber battens, galvanised

nails or steel saddle clips. By fitting premium performance rigid insulation, it should be possible to maximise heat retention within these applications.

For properties with solid floors, fitting both UFH and insulation can be more challenging. The most obvious solution is to install both systems over the existing floor slab, but installing a sufficient thickness of traditional insulation products can require the existing floor level to be significantly raised. This may not be possible if the floor to ceiling height is already relatively small and will require all fittings such as skirting boards and plugs to be raised.

The alternative is to remove the existing floor slab and dig down. This requires a substantial amount of manual labour, extending project timescales and causing high additional costs and disruption for owners. The Kingspan Flooring System can offer a slim-line solution.

1 Barbour Product Search – Key Trends in UK Underfloor Heating (https://www.barbourproductsearch.info/key-trends-in-the-uk-underfloor-heating-market-blog000344.html)

VACUUM INSULATION PANELS (VIPS)

Kingspan VIPs feature a microporous core which is evacuated and sealed in a thin, gas-tight envelope. The envelope is capable of withstanding atmospheric pressure, and of maintaining the vacuum over time. This vacuum technology allows panels to achieve an aged thermal conductivity as low as 0.007 W/m•K – up to five times better than that of commonly used insulation materials. As a result, they can deliver the desired U-value with a much thinner construction than would otherwise be possible.

Kingspan VIPs are accompanied with Kingspan flex infill strips of the same thickness. These strips can be cut to size to fill awkward spaces or to allow penetrations through the floor layer. Our tailored design service ensures the best possible ratio of Kingspan infill strips to VIPs and provides clear installation guidance.

The Kingspan Flooring System is ideal for UFH retrofits on solid floors as its outstanding thermal performance

minimises the required thickness of the insulation layer. In high-ceilinged properties, this can allow the existing floor slab to be retained. In cases where the floor to ceiling height is more limited, it can reduce the amount of digging down required to maintain the existing floor level after the UFH system is installed.

In either case, the Kingspan Flooring System should be fitted above the floor slab, damp proof membrane and a protection layer. By fitting the insulation above the floor slab, heat is retained within the building envelope, helping the property to respond more rapidly to the UFH once it is turned on. A polyethylene separation layer should then be fitted, followed by the UFH system and screed, taking care to not damage or penetrate the Kingspan VIPs during the process.

AVOIDING PROBLEMS The performance of the floor insulation layer is the most obvious consideration in any UFH application. However, with water UFH systems operating at a lower temperature than conventional radiators, it is also important to assess the overall airtightness and thermal performance of the building envelope. If improvements are required then Kingspan VIPs or our Kingspan Kooltherm® K100 range products can often provide a slim solution, maintaining living space and helping to maximise the efficiency of the UFH system.

CASE STUDY

STAYING IN SHAPE WITH KINGSPAN KOOLDUCT®

The Kingspan KoolDuct® System and circular ductwork formed from Kingspan KoolDuct® Panels offered an innovative HVAC solution for this phase. Unlike galvanised steel, both systems are pre-insulated using Kingspan KoolDuct® Panels. This design eliminates the time-consuming lagging stage and can save as much as 200 mm ceiling void space in a single dimension. This was a key consideration on the project as cg3 Systems had to install the new ductwork within pre-castellated steel beams.

Rori Millar, BIM and Coordination Manager at cg3 Systems, discussed the challenge:

“Due to the castellated beams, it was essential that the quantities of ductwork were almost millimetre perfect. This required careful clash detection implementation, measurement and coordination. The 3D modelling as part of the BIM process at pre-site stage, in addition to guidance and support from Kingspan’s superb technical team,

ensured the ductwork systems would fit properly. Onsite, it was installed exactly in accordance with the 3D models, and included many offsets and pieces which simply wouldn’t have been possible with sheet-metal type ductwork.”

The rigid phenolic core of Kingspan KoolDuct® Panels can achieve thermal conductivities as low as 0.022 W/m•K and have been assigned a BRE Green Guide Summary Rating of A. Ductwork fabricated from the Kingspan KoolDuct® System can reduce air–leakage rates to a fraction of those typical of rectangular sheet metal ductwork. This innovative System thus offers the triple benefits of cutting energy use, cutting operational carbon dioxide (CO2) emissions, and cutting costs.

Kingspan KoolDuct® Panels are suitable for internal and external applications. Their rigid phenolic insulation core is manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).

A number of aspects of the building envelope are considered as part of a fabric-first approach:

The first step in a fabric-first approach is to review the building structure (fabric) and to ensure that it is designed to limit unnecessary heat loss and energy usage. Only once this has been achieved are energy generation technologies, such as biomass boilers or photovoltaic panels, considered.

There are several reasons why this approach is favoured on many modern projects. Energy generation technologies often come with a significant upfront cost, most require regular maintenance to ensure they are functioning effectively and their expected lifespans are limited when compared with that of the building. All of this can add on-going cost and inconvenience to building owners.

In contrast, the passive measures used within fabric-first constructions should continue to deliver throughout a building’s lifecycle with little if any upkeep. This makes them both a reliable and cost-effective means of reducing long-term energy usage and carbon emissions.

THERMAL PERFORMANCE The most obvious way to limit heat loss from the building envelope is by improving the thermal performance of the different building elements (floors, walls and roof). As we discussed on page 4, the lambda value (thermal conductivity) of the insulation layer is critical in these specifications. Insulation with a low lambda value, such as the rigid phenolic insulation used in our Kingspan Kooltherm® K100 range of products, can achieve the desired thermal performance with a slimmer product and construction thickness when compared with worse performing insulation materials.

In practice, this can limit the number of deliveries to site, allow simpler manual handling and potentially reduce structural requirements. In addition, when applied to external walls it can help to maximise useable space within the building envelope. Back in 2015, we commissioned a report from Sweett Group to assess the value of

There are several ways to address these areas. One of the most common in conventional cavity wall constructions is by installing insulated cavity closers around windows and doors. Meanwhile, modern methods of construction, such as structural insulated panels, are often designed to allow greater continuity of insulation in these areas, helping to limit this issue simply and effectively.

AIRTIGHTNESS The final consideration for designers taking a fabric-first approach is air leakage through the building envelope. Older properties were often designed to allow a certain degree of natural airflow to ventilate internal rooms. However, by sealing rooms to cut out cold draughts and instead regulating airflow with mechanical ventilation, modern approaches can achieve a much higher degree of energy efficiency whilst maintaining a comfortable, controlled internal environment.

space recovered by installing Kingspan Kooltherm® rather than lower performing insulation products within commercial properties. The report showed that through this additional space, owners could achieve a return on investment of as much as 4000% on the product cost when compared with other common insulation solutions (kingspaninsulation.co.uk/realvalueofspace).

THERMAL BRIDGING Jonathan Ducker looked in detail at the topic of linear thermal bridges in the Spring Issue of Insulation Insight. In a nutshell, linear thermal bridges describe the heat loss / gain at junctions and around openings which interrupt the insulation layer. These areas take on even greater importance when the envelope is highly insulated as heat naturally flows through these paths of least resistance. As a result, poor detailing around these areas can badly undermine the overall performance of the building envelope.

The initial requirements within Part F of the 1965 Building Regulations (which came into force in February 1966) were relatively lax, applying only to the walls and roofs of certain buildings, but it marked the beginning of 50 years of significant change. Today, under Part L, the thermal performance of buildings is a fundamental consideration on all construction projects with many now adopting a so called “fabric-first” approach. So, what does this mean in practice?

PUTTING FABRIC FIRST

In England, 1966 will always be synonymous with the country’s World Cup victory. The events at Wembley were just one amongst many firsts in a year which saw Star Trek and Batman beamed to TV sets, Action Man on the toy shelves and Harrier Jump Jets redefining aeronautics. In the built environment, it was also the first time that minimum fabric performance requirements were included within the UK Building Regulations.

ALL ENVELOPING PASSIVE PRACTICE

WEAVING A BETTER BUILT ENVIRONMENT The fabric-first method is at the heart of the current Building Regulations and Standards across the UK, whilst approaches such as the Passivhaus Standard (discussed on page 8) are well recognised for their success in delivering energy efficient buildings. By installing premium performance insulation products, such as those within our Kingspan Kooltherm® K100 range, it should be possible for project teams to keep constructions slim whilst also delivering excellent fabric performance – creating spacious, warm and comfortable spaces for living and working.

PROJECT FACTSGRANDY’S CROFT

Grandy’s Croft, a low-rise block of six flats in Solihull, has been upgraded using a revolutionary off-site solution.

With new insulation installed, it is anticipated that tenant’s energy bills will be reduced by 85%, from £1,064 per flat to just £166 per year.

An innovative large-scale whole building retrofit system installed on a social housing development has dramatically reduced its energy requirements to EnerPHit standards.

LOCATION:Chelmsley Wood, Solihull

Grandy’s Croft, a low-rise block of six flats in Solihull, has been upgraded to meet the demanding EnerPHit Standard using a revolutionary off-site, wrap-around large scale (OWLS) retrofit solution: the Beattie Passive TCosy™. Funded by Innovate UK through their ‘Scaling-up Retrofit Competition’, the pilot project was a collaboration between Solihull Community Housing, system designers and installers, Beattie Passive, and Passivhaus consultants and project managers, Encraft. Additional technical and tenant management support was also provided by Coventry University.

The all-in-one retrofit solution was installed around the existing building to create a highly-insulated envelope, limiting thermal bridges. Kingspan Kooltherm® K5 External Wall Board was selected as a key component of the system due to its ability to deliver premium thermal performance relative to its thickness. Ron Beattie, Managing Director of Beattie Passive, explains further:

“The TCosy™ system offers a simple, highly replicable solution for deep retrofit. Using the Kingspan Kooltherm® K5 External Wall Board within our retrofit system has helped us to achieve U-values of just 0.099 W/m2•K for the walls and an airtightness test result of 0.93 air

changes per hour (ach) @ 50 Pa. These calculations mean that the retrofit system easily meets EnerPHit Standards.”

Due to the level of airtightness, it was also necessary to install a Mechanical Ventilation and Heat Recovery (MVHR) system. The ductwork could not be installed inside the properties themselves, so Beattie Passive utilised their patented void around the outside of the building to incorporate the services.

Tenants remained in their homes for the duration of the project and have already been enjoying the benefits of living in a healthier, more comfortable environment. Mark Pinnell, Head of Asset Management at Solihull Community Housing commented:

“We have a strong commitment to improving the energy efficiency of our homes and this project makes a real contribution.”

Coventry University, in collaboration with the contractors, building owners and tenants, will be carrying out ongoing monitoring of energy usage, temperature and indoor air quality in the flats to ascertain the impact of the project.

CASE STUDY


TIMBER TRANSFORMATION – THE RICH HISTORY AND BRIGHT FUTURE OF TIMBER FRAME CONSTRUCTION

A BRIEF HISTORY OF TIMBER FRAME CONSTRUCTION The bio-degradable nature of wood makes it extremely difficult to accurately estimate when the first wooden structures were created. However, recent archaeological discoveries in Leipzig show that it was already in use by the period 5600 to 4900 BC. In the UK, the oldest wooden building still in use is Greensted Church, which contains timber planks estimated to date back to 1060 AD.

Timber frame was the dominant form of construction in Britain from the Middle Ages right through to the early Stuart period, with Britain’s large native woods making it a cheap, fast and affordable construction solution. This began to change by the mid-17th Century for a variety of reasons. The lack of effective building regulations meant many timber frame buildings were susceptible to rot – greatly reducing their lifespan when compared with other construction methods. Overcrowded timber buildings also exacerbated the risk of fire and was a key factor in the rapid spread of the Great Fire of London. Finally, Britain’s oak woodlands had been largely exhausted, making timber much more expensive. As a result, by the Victorian period, the timber

structural elements of most UK buildings were largely consigned to the roof and internal floors of the building.

It was not until the 1960s that timber frame construction began to see a revival as a long-term housing solution – even then, the change was largely restricted to Scotland. The cooler, wetter climate north of the border made timber frame a logical choice – allowing buildings to be constructed rapidly and delivering improved fabric performance compared with other methods of the time.

Today, around 75% of new Scottish homes are constructed using structural timber frames, and increasingly housebuilders across England and Wales are embracing its benefits. In 2005, structural timber frame constructions accounted for 19.7% of all house constructions in the UK and by next year it is predicted to account for one third of developments1.

MODERN FORMS Today, the most common structural timber frame approach is an open panel construction. A recent survey from the National House Building Council shows that around 70% of companies surveyed had used open panel constructions in the past three years, and around half expected to use it in 20162.

In an open panel construction, the skeletal timber frame panels are pre-fabricated offsite without any vapour control or insulation. Once the panels are erected and made weathertight and the initial electrical and plumbing work is carried out, insulation can be fitted within the stud cavity.

Modern, premium performance insulation products such as our Kingspan Kooltherm® K100 range can achieve thermal conductivities as low as 0.018 W/m•K. This can help housebuilders meet the desired level of fabric performance with a minimal construction depth.

Whilst open panel constructions can reduce project timescales when compared with conventional masonry constructions,

they still require significant sitework. Closed panel constructions provide a more truly offsite method of construction. These systems are typically pre-insulated and the panels are sometimes supplied with services and windows pre-fitted within the factory.

Structural Insulated Panels (SIPs), such as our Kingspan TEK® Building system, provide a third offsite method of timber frame construction. SIPs comprise an insulation core typically faced on either side with particleboard or oriented strand board. The panels are pre-cut to a project’s unique design in a factory, and once delivered to site, fit together tightly like a 3D jigsaw with little or no corrections or site waste.

The panelised nature of all three methods of offsite construction enables much greater scheduling predictability, particularly in the case of SIPs and closed panel constructions. Furthermore, as they’re primarily dry methods of construction, there is less time lost to bad weather or simply waiting for wet trades to set.

Timber constructions also allow a great deal of variety in the final appearance of the building. Over recent years Kingspan TEK® Building System homes have been built in the style of a period barn, a traditional brick-faced house and even an industrial COR-TEN clad home.

A BRIGHT FUTURE The wide range of benefits offered by timber construction methods means they are here to stay. When partnered with the right insulation products, they can not only help to meet the demand for quantity and reduced levels of skilled labour, but also help to deliver energy saving benefits to homeowners over the long-term. Now someone just needs to let the children’s book publishers know.

The fate of the little pig who built his home from wood varies from telling to telling, what is clear though is that his home failed to stand up to the wolf’s wind load testing. The parable, in the version we know today, dates to the mid to late Victorian period and says much about British attitudes on the use of timber frame constructions at the time. If you wanted a solid home, it had to be brick-built and, in England at least, that remained the same throughout the 20th Century.

The housing and skills shortages have, however, forced an industry rethink and timber frame housebuilding has seen a spectacular year-on-year rise. To understand why attitudes have changed, it is useful to look back at the construction method’s history in Britain, the reasons behind its fall from grace, and its modern forms.

GROWING THE FUTURE WITH LEINTWARDINE PRIMARY SCHOOL

WOOLY MOWERS’ TO THE RESCUE FOR SHERBURN WILLOWS

The children at Leintwardine Primary School are feeling empowered to make a difference with their Keyhole Kitchen Garden project, organised with help from funding from the Kingspan Insulation Community Trust.

Fuelled by its pledge to be ‘Waste Watchers’, Leintwardine Primary School and its partner school in Tanzania have been taking part in a joint learning project about kitchen gardens. Headteacher, Anne Brandrick, went over to Nganana Primary School to learn more about the gardens and their benefits. She explains:

“The gardens are a raised circular bed of compost with an access point in the middle, to ensure crops can be watered efficiently. Water is such a precious commodity in countries such as Tanzania and it is vital that crops grow well so that there is enough

The wildflowers of Sherburn Willows have been

saved from the threat of invasion by a flock of

horned helpers. Yorkshire Wildlife Trust brought in

the Hebridean sheep to manage grassland within

the reserve and the flock are now free to graze a

larger area thanks to new fencing, purchased with

a grant from the Kingspan Insulation

Community Trust.

Sherburn Willows is a small nature reserve near

the Parish of Sherburn in Elmet. It features a rare

strip of species-rich magnesia limestone grassland

which brims with colour throughout the spring

and summer months. Yorkshire Wildlife Trust had

already purchased the flock to graze one area of

the grassland, however, with bramble and other

undesirable species slowly taking over the rest of

the meadow, it was clear the sheep’s enclosure

needed to be expanded.

Following a successful application, the Kingspan

Insulation Community Trust provided grant funding

of £6,971. The money was used to fund the repair

and extension of the pen fencing, including the

installation of gates to allow resident access, and

the cutting out of the scrub and bramble.

Karen McDiarmid from Yorkshire Wildlife

Trust commented:

“Magnesia Limestone grassland is nationally

scarce and many of the species of wildflower

found within the reserve will only grow on this

soil. With the funding, and help of our sheep and

local volunteers, we’ve been able to preserve

the diverse wildflower population, keeping the

meadow a wonderful place for visitors to come

and relax. We’ve also held a number of ‘Meet the

Sheep’ events, where locals can come and learn

about the reserve ‘lawnmowers’ and why they’re

so important.”

John Garbutt, Chairman of the Kingspan Insulation

Community Trust added:

“It is vital that we preserve and care for the

rare populations of wildflower that makes our

countryside so special. Encouraging biodiversity

is one of the four key aims of the Community

Trust and we were delighted to be able to

support the excellent work being carried out

at Sherburn Willows”.

food for families to eat. To help the children back at the school understand more about how some countries have limited food and water, and why it is important to make better use of the resources we have, we decided to build our own keyhole garden.”

The school successfully applied for £300 from the Kingspan Insulation Community Trust. Made from compost from the school’s compost bin, and watered with waste water from the classrooms and rainwater barrel, the garden provides a great resource for the whole school to learn about these issues. A visit from a teacher from Nganana Primary School has helped the young gardeners to get to grips with effective gardening techniques, and furthered their understanding of the challenges of growing food in a hot climate with limited resources.

Chairman of the Kingspan Insulation Community Trust, John Garbutt, added:

“It is vital for us to educate young people, the consumers of the future, about the importance of making waste reduction a habit and how the food they eat is grown to benefit both their health and the environment. The Kingspan Insulation Community Trust was thrilled to be able to help the school set up a project which can be enjoyed for many years to come.”

Leintwardine Primary School have been learning all

about the importance of keyhole gardens, thanks to

funding from the Kingspan Insulation Community Trust.

It had to be ewe: Sherburn Willows nature reserve

has been returned to health by its dedicated team

of herbivorous helpers.

PROJECT FACTSFITZROY PLACE

A stylish development in the heart of London is the latest project to benefit from the excellent thermal efficiency of products from the Kingspan Kooltherm® range.

Fitzroy Place has been constructed on the 3-acre site of the old Middlesex Hospital. The original site was completely flattened aside from the chapel and sections of the original Victorian façade. This gave developers, Exemplar and Aviva Investors, a blank canvas on which to create the new mixed-use estate. Sheppard Robson and Lifschutz Davidson Sandilands prepared the ambitious design which includes 235 private apartments, 54 affordable homes, two office buildings, restaurant and retail spaces.

The estate, constructed by Sir Robert McAlpine, has been designed with a focus on detail and quality which extends to the energy performance of the development. The domestic elements of the site achieve an enhanced level of energy efficiency when compared with the Building Regulations, whilst the office blocks hold a BREEAM rating of ‘Excellent’. To meet these requirements, a fabric-first approach was adopted and several Kingspan Kooltherm® products were specified across the site.

The façade of the new buildings combine brick, concrete and glass, drawing inspiration from the original red-brick hospital buildings and the ‘white working buildings’ of the area north of Oxford street. Kingspan Kooltherm® K15 Rainscreen Board was used to insulate the rainscreen elements of the façade whilst Kingspan Kooltherm® K12 Framing Board was installed between timber battens on masonry sections of the external walls.
