External Wall Insulation Why External Wall Insulation? PermaRock external wall insulation systems have been used successfully for over 25 years in the UK and the technology for more than 40 years in Europe on social housing applications. With 35-45% of heat lost through the walls on ‘hard to treat’ and solid wall homes, the application of a PermaRock external wall insulation (EWI) system will provide a number of positive benefits to the building occupants: Our systems were developed in the UK to address issues found in post-war housing stocks, particularly for application on to solid wall and ‘Hard To Treat’ homes that are not able to benefit from cavity wall insulation. PermaRock systems are suitable for application in areas classified as having very severe exposure - i.e. the whole of the UK. Systems have BRE accreditation with minimum lifetime expectancies in excess of 30 years and are now widely used across all market sectors, both on new and existing buildings. Why Insulate? There are many reasons and factors why you should consider insulating a building and improving its thermal performance, these include the following: • To reduce the amount of energy consumed by buildings and reduce fuel bills • To reduce emissions of CO2 and other greenhouse gases • To reduce condensation and dampness and the associated health problems • To increase comfort levels within the home environment Building Regulations, Government Legislation & Initiatives (CERT/CESP/Decent Homes/Green Deal Strategy) may also make thermal improvements a requirement or a more attractive improvement to undertake. • Lower fuel bills: The installation of an external wall insulation system has a ‘thermal jacketing’ effect that causes heat energy losses through the external wall to be reduced. High levels of energy efficiency can be achieved over other forms of insulation resulting in savings on energy bills, especially where other measures are not suitable (non-cavity/solid wall properties). An average semi-detached home could typically save £400 - £500 per year on fuel costs (Source: Energy Savings Trust) • A PermaRock EWI or render system protects the building fabric from the worst excesses of the weather and allows damp structures to dry out. As a result, the building can expect a longer useful lifetime • An external wall insulation system when detailed correctly overcomes the effects of cold bridging, thereby eliminating condensation and dampness • The original wall construction can be used as a heat store. This thermal mass helps to reduce temperature fluctuations and maintains a more comfortable internal environment • Systems are durable and cost effective and can improve the appearance of older buildings • Application can take place without disruption to the occupants and there is no reduction in interior living or working space Different Types Of Insulation Measures External Wall Insulation Cavity Wall Insulation Internal Insulation Very high levels of insulation possible Cost effective solution for existing cavity walls Provides rapid response to heating Overcomes cold bridging, condensation and dampness Insulation thickness limited by size of cavity Suitable when external appearance can’t be changed - i.e. conservation areas or to meet specific planning requirements Building fabric is protected (extends buildings life) Does not eliminate cold bridging Reduces room size Effective for new and existing buildings No protection afforded to outer leaf Cold-bridging possible Enables building appearance to be improved / modified Unsuitable with solid wall ‘hard to treat’ houses No protection to the building fabric No internal disruption Unsuitable for very exposed sites Applicable to any wall type 06 Typical external wall insulation build up Installation to existing buildings is disruptive External Wall Insulation - Design Considerations PermaRock’s Area Sales Managers and Technical Department are available to provide assistance and advice with external wall insulation (EWI) system specification as there are number of considerations that could affect the choice of system and decorative finish proposed: • Type of Building/Wall Build-Up: The system choice should be suitable for its application (low-rise or high-rise) and for the wall construction type. The building should be structurally sound to accept the system load (a structural survey maybe required) and where necessary, any structural and preliminary works need to be carried out before the EWI system is installed. • Thermal Performance: What is the required U-value (see pages 16 & 68 for further details) and are there limitations to the thickness of system which can be accommodated? • Fire Performance: The system should be suitable for low-rise and/or highrise application and, where required, should incorporate fire performance or fire-breaks to meet with Building Regulations and BR135 requirements. • Environmental Performance: The system should incorporate insulation materials which are CFC/HCFC free and which do not employ ozone depleting chemicals in their manufacture. The specifier may also wish to take into account any Eco-points rating a system may have achieved through a life cycle assessment. This process measures its environmental impact during the systems economic life, from the extraction of the raw materials and components to the disposal (and recycling) of the product at the end of a 60 year life cycle (i.e. cradle to grave). • Adaptations: Roof overhang, window & door replacements, plumbing, heating and ventilation requirements should be considered prior to the installation of the EWI system. • Aesthetics: Is the desired finish and colour available and is the decorative finish suitable for its intended location and exposure? • Cost: A number of factors can have an effect on the cost of the system including insulation type and thickness as well as the choice of decorative finishes - PermaRock can advise on the implications of proposed choices to the cost of the system. • Impact Resistance: The decorative finish is selected primarily based on the desired aesthetic appearance whilst also considering the level of impact resistance necessary. Where required, additional reinforcement can be incorporated into the system design. 07 02 What Is External Wall Insulation? Preliminary Works & Application External Wall Insulation Approved Applicators Walls must be sound and dimensionally stable and capable of withstanding the additional load imposed by an external wall insulation system (a structural survey may be required) and unless otherwise specified, the system is typically installed from DPC level (insulation below DPC floor level is also advisable), working upwards and is normally applied (dependant on access) from scaffold or mast climbers. PermaRock external wall insulation systems incorporate rigid insulation boards in thicknesses to suit individual project requirements. Insulation boards are mechanically fixed, with additional adhesive bonding if required, or adhesively bonded with supplementary mechanical fixings. After fixing, the boards are ready to receive a PermaRock high polymer content cementitious base coat and glass fibre alkali resistant reinforcing mesh. Corners are reinforced with pre-formed protection profiles. Installation of PermaRock systems is undertaken by our nationwide network of trained and approved applicator contractors. All preparatory works and adaptations (i.e. rainwater goods / waste pipes / overflow outlets / soil stacks / boiler flues / roof overhang, etc.) are also completed before installation. Application will occur whilst the building occupant is insitu and disruption is minimal, however, as part of the installation process drilling and mixing machines will be in use whilst work progresses. Allowing for normal weather conditions and all necessary preliminary works, installation on a typical semi-detached house can take between 2 – 3 weeks. Dependant on the decorative finish, typically a second coat of PermaRock high polymer content cementitious bedding mortar coat will be applied along with the chosen decorative finish. Systems come complete with a full range of profiles, trims and accessories to achieve weather-tight and durable details in compliance with the principles of robust construction. Approved applicator personnel receive regular training updates and are kept abreast of the latest innovations and product developments. The performance of the applicators is constantly monitored to ensure continuing satisfactory performance. PermaRock operate an Identity Card system for trained external wall insulation site operatives. The cards are monitored and checked by System Technicians during routine site visits to ensure system installation is undertaken by correct personnel and that quality standards are maintained. PermaRock approved applicators operate in all areas of the UK. PermaRock can provide details, on a project-byproject basis, of approved applicators capable of carrying out the installation of any PermaRock system based on a projects size, location and programme requirements. Many of PermaRock's applicators are of sufficient size and calibre to undertake general building works and the full main contractor role, providing a full package of access, site supervision and management, and fulfilling the requirements of Health & Safety / CDM regulations, etc. Maintenance Advice Typical External Wall Insulation System Incorporating Through-Coloured Render Finish Adhesive Insulation Board Bedding Mortar Reinforcement Bedding Mortar The successful installation of a PermaRock system is not the end to PermaRock's involvement with a project. PermaRock provides a full aftercare package including telephone support, on-site and office based technical service as well as ‘Care & Repair’ manuals for its systems, detailing how maintenance teams can carry out routine tasks such as cleaning, effecting minor repairs, or modifying or adding new fixtures and fittings. PermaRock’s Area Sales Managers and Technical Services team are available to discuss completed projects and to provide any necessary support or assistance when you wish.

Many buildings were designed without any form of insulation in the walls, and even those buildings with cavity walls which have subsequently been fitted with cavity insulation can fail to meet the stringent thermal performance requirements of the current Building Regulations and Decent Homes Standards. Many existing buildings also suffer from cold bridging and the associated problems of dampness and condensation which can have health implications for building occupants. Building owners are also faced with ever increasing costs for heating and maintenance whilst at the same time being asked to reduce energy consumption in support of global efforts to reduce CO2 and other greenhouse gas emissions. BISF Steel Frame House: After EWI installation Reducing heat energy losses through the external envelope and eliminating problems associated with condensation and dampness is a key issue for both social housing and for commercial redevelopment, for high-rise and low-rise, traditional and non-traditional forms of construction. Complete remodelling of the building façade is also possible with PermaRock. The wide range of decorative finishes and effects that are available with PermaRock systems provides the designer or specifier with the means of creating interesting and aesthetically pleasing façades that either compliment the original style or which can create a whole new impression. PermaRock systems are available for all types of construction, including solid wall or cavity wall, concrete, steel or timber frame, dense and no-fines concrete, brick and stone, rendered, metal clad, tile clad or timber clad structures. PermaRock systems have been designed for use on high and low rise buildings, for traditional and non-traditional forms of construction, including many pre-cast reinforced concrete (PRC) types, in exposure conditions ranging from sheltered to very severe. 10 PermaRock systems can achieve very high standards of thermal insulation, not only up to current Building Regulations requirements for new buildings but also beyond predicted future energy-saving and CO2 reduction requirements: PermaRock systems can be designed to meet or exceed any future reduction in Uvalues that may be imposed. Please be aware external wall insulation changes the appearance of a building so planning permission may be required. This is particularly relevant in conservation areas. 11 03 Retrofitting External Wall Insulation Low-Rise Housing Solid or cavity wall. Concrete, timber or steel frame. Houses, bungalows or flats. Traditional or nontraditional build. PermaRock offers complete technical solutions to meet the external wall insulation requirements of all forms of low-rise housing. With traditional solid wall or cavity wall construction, PermaRock systems can provide all levels of rejuvenation from a simple aesthetic uplift, using a high performance exterior render system, to full thermal performance improvements, elimination of cold bridging and condensation using a fully accredited external wall insulation system (EWI). A PermaRock EWI system provides immediate benefits in terms of heat loss reductions and savings in heat energy costs. The system protects the building fabric, extending the useful life of the structure, and offers the opportunity for improving the appearance using any of our range of low maintenance exterior finishes and effects. PermaRock systems can be designed to deliver U-values that are considerably better than current Building Regulations requirements, and systems can be designed for application to walls that have already been treated with cavity insulation, to provide further improvements in thermal performance whilst shifting the structural dewpoint to the outside, thereby eliminating the risk of interstitial condensation. Unity Non-Trad House: After EWI Refurbishment ‘Hard To Treat’ Homes - Solid Wall & Non-Traditional Housing PermaRock systems have been used extensively across the UK, from the Shetland Islands and Western Isles in the North, to the extremities of Cornwall in the far South West, in urban and rural environments and in exposed and sheltered locations. PermaRock systems are designed to provide thermal and aesthetic improvements to all forms of housing but are especially suited for application onto ‘Hard To Treat’ homes, such as solid wall and non-traditional housing or where cavity wall insulation is not suitable or possible. PermaRock external wall insulation (EWI) systems provide a thermal jacketing effect that stabilises the structure by reducing thermal movements whilst protecting the building fabric from water and weathering, extending the buildings useful life by a minimum of 30 years whilst enhancing comfort levels by eliminating cold bridging, dampness and condensation. The application of a PermaRock EWI system will raise the temperature of the building fabric, reducing interstitial condensation and dampness, allowing drying out to occur. Reduction in the moisture content of concrete reduces reinforcement corrosion and can therefore prolong the life of the structure - a particularly important effect with PRC (prefabricated reinforced concrete) buildings. Non-Traditional Housing PermaRock is able to offer solutions for many PRC house types, as well as for other non-traditional or system built types, including the following: • • • • • • • • • • Airey BISF Bison Cornish Dorran Easiform Hawthorne-Leslie Hawksley BL8 Orlit Reema • • • • • • • • • Spooner Swedish Timber Frame Tarran Trusteel Unity Vic Hallam (various) Wates Wimpey No-Fines Woolaway Please note that a structural survey may be required as properties should be structurally sound to accept the EWI system load. 12 13 03 Retrofitting External Wall Insulation High-Rise Buildings High-rise buildings present a number of interesting technical challenges for the external wall insulation system designer. In addition to experiencing greater structural movement and higher wind suction forces than low-rise buildings, high-rise structures are riskier in terms of fire propagation, and are less likely to see regular exterior maintenance than their low rise counterparts. The installation of an external wall insulation system to a high rise building is a longer process than with low-rise buildings, and the various elements forming the system may therefore be exposed for some time before the final rendered surface is achieved. It is important that façade systems for high-rise structures are designed with specific regard to these particular technical requirements. PermaRock’s track record with high-rise is second to none, and our award winning systems have been designed to provide excellent thermal performance as well as total resistance to driving rain and high negative wind pressures. PermaRock systems are tough and durable, will withstand extremes of temperature and have very low maintenance requirements. But more than just providing systems that fulfil the technical requirements of high-rise buildings, PermaRock offers the widest choice of decorative finishes and effects giving the designer freedom of expression to create interesting and pleasing façades. With high-rise buildings, the use of contrasting colour and texture enables the scale of buildings to be accentuated or diminished. Additional relief modelling, using extra layers of insulation or preformed insulation sections can be used to 'break up' the façade or to introduce curves into otherwise flat elevations. PermaRock’s products and systems provide a totally flexible approach to rejuvenating high-rise buildings, combining good looks with practicality, satisfying the needs of the building owner and the occupants, the specifier and the installer. The PermaRock Mineral Fibre and PermaRock Lamella Systems are fire-safe during all phases of installation, not only after the final coat of render has been applied and are recommended for multi-storey buildings where optimum performance in relation to fire is paramount. PermaRock systems can be applied to almost any substrate type, including brick, dense and no-fines concrete, blockwork, solid wall, cavity wall or panel (fair faced, exposed aggregate or ribbed) constructions. Where the building façade requires remodelling, perhaps by the extension of the external walls to enclose balconies using a lightweight metal frame, timber frame, or SIPS construction method, PermaRock systems still provide the optimum overcladding solution. PermaRock systems are lightweight and easy to install from a traditional scaffold or from mast climbers. Installation is carried out by trained, specialist applicators monitored by PermaRock. The issue of fire safety is particularly important with high-rise buildings. PermaRock has a range of systems that offer the opportunity of CFC/HCFC free insulation that meets the requirements of Building Regulations and BS 8414 and can be designed for use on high-rise buildings without the need for fire breaks. 14 15 03 Retrofitting External Wall Insulation U-value Requirements: Hard-To-Treat & Non-Traditional Constructions The following tables provide and indication of the insulation thickness required to achieve a range of U-values for walls of a number of non-traditional house types: Wall type / U-value (W/m²K) Solid Brick (229mm) 0.35 0.30 0.25 0.20 0.15 0.10 Mineral Fibre (mm) Insulation type and thickness Phenolic (mm) EPS (mm) 90 100 120 160 N/A N/A 50 60 75 95 N/A N/A 90 110 130 170 230 N/A EPS-Premium (mm) 80 90 120 140 180 280 Non-Traditional House Types: Airey* (PRC Post/Panel) 0.35 0.30 0.25 0.20 0.15 0.10 80 100 120 150 N/A N/A 50 60 80 100 N/A N/A 90 110 140 170 250 N/A 70 80 100 130 130 280 BISF* (Existing cladding removed and replaced with plywood sheathing) 0.35 0.30 0.25 0.20 0.15 0.10 80 100 120 160 N/A N/A 50 60 80 100 N/A N/A 90 110 130 170 230 N/A 80 100 120 140 200 300 Cornish (PC Panel/PRC Post) 0.35 0.30 0.25 0.20 0.15 0.10 90 100 130 170 N/A N/A 50 60 80 100 N/A N/A 90 110 140 180 240 N/A 80 90 120 150 210 300 Mineral Fibre (mm) Insulation type and thickness Phenolic (mm) EPS (mm) Orlit (PRC Panel) 0.35 0.30 0.25 0.20 0.15 0.10 80 90 110 150 200 N/A 50 60 70 90 N/A N/A 80 100 120 160 220 N/A 70 80 110 140 190 280 Reema (PRC Panel) 0.35 0.30 0.25 0.20 0.15 0.10 70 80 110 140 190 N/A 40 50 70 90 N/A N/A 70 100 110 150 210 300 60 80 100 130 180 300 Wates (PRC Panel) 0.35 0.30 0.25 0.20 0.15 0.10 80 90 110 150 200 N/A 50 60 70 90 N/A N/A 80 100 120 160 220 N/A 70 80 100 140 190 280 Wimpey No-Fines (No-fines Concrete) 0.35 0.30 0.25 0.20 0.15 0.10 80 100 120 160 N/A N/A 50 60 80 100 N/A N/A 90 110 130 170 230 N/A 80 90 110 140 200 300 Wall type / U-value (W/m²K) EPS-Premium (mm) Key: N/A - Please contact PermaRock for advice. * Existing cladding replaced with new timber sub-frame and plywood sheathing.

Simmonds Specifier: Peabody Design Group Substrate: Solid Brickwork 9” & 13” System: PermaRock 90 mm Mineral Fibre External Wall Insulation System Wall U-Value Achieved: 0.35 W/m²K System Finish: PermaRock Acrylic K 1.5 mm Finish Solar House, prior to its transformation, was a traditionally built, flat roofed, 4 storey building with poor thermal efficiency typical of its type and period. The client, Peabody Trust, saw the refurbishment of the block, utilising the PermaRock Mineral Fibre External Wall Insulation System, along with the introduction of solar technology as an ideal solution to its commitment to its sustainable development of its housing stock. PermaRock supplied a 90 mm mineral fibre insulated render system to achieve a U-value of approximately 0.35 W/m²K to the brick wall areas. Pre EWI installation 18 In addition to the use of external wall insulation (EWI), the client also incorporated banks of photovoltaic panels in the new roof, which provide electricity, heating and lighting for its residents and along with the EWI has resulted in a reduction in carbon emissions. The application of the insulation on the outer wall also ensured that maximum technical benefit was gained from using the insulation. Interstitial condensation in the wall structure was eradicated as the dewpoint was moved to the outside of the building, whilst a mineral fibre based system was chosen for its fire resistant properties. Aesthetically, the use of PermaRock’s K 1.5mm textured render, in two contrasting colours, complemented the timber cladding giving the refurbished block the appearance of a newly built residential development. The combination of the insulation to the external wall envelope and solar panels to the roof makes this project one of the most energy efficient refurbishment schemes on a residential block in recent years. Post EWI installation Specifier: Simmonds Mills Architects Substrate: Solid Brickwork System: PermaRock 250 mm EPS-Premium External Wall Insulation System Wall U-Value Achieved: 0.11 W/m²K System Finish: PermaRock Silicone K 1.5 mm Finish PermaRock’s EPS-Premium external wall insulation (EWI) system was installed as part of a number of energy efficient retrofitted measures to a detached 1869 Victorian house in Hereford to help contribute towards creating a low-energy, Passivhaus standard, building. This set extremely challenging targets for improving the thermal performance of the building fabric through high levels of insulation, ‘thermal bridge-free’ junctions between walls, floors and roofs etc and aiming for a very airtight building envelope of 0.75m³/m²hr @50 Pa in the final test 0.97m³/m²hr @50 Pa was actually achieved an excellent result: 2010 Building Regulations require an airtight building envelope of 10.00m³/m²hr @50 Pa. Arguably the biggest contributor in achieving the required standards was the use of the PermaRock EPS-Premium external wall insulation system, which incorporated 250 mm of high performance expanded polystyrene insulation, and helped bring the U-value of the external solid brick walls down to 0.11W/m²K. Prior to the recently completed works, the solid brick cottage had difficulties in achieving and maintaining an even temperature in such a poorly insulated and draughty house and the expenditure of all this energy never resulted in a healthy or thermally comfortable environment. With this in mind the owners decided that the time had come for a radical improvement to the insulation and energy standards of the house. To meet their own expectations, a successful outcome for the project would result in whole house CO2 emissions for heat and power being reduced by approximately 80 - 85% compared, to the average measured performance of a typical UK house of the same size. The adhesively bonded and mechanically fixed system had to overcome a number of issues during design stage to enable Carbonlite/Passivhaus targets to be made possible. As well as having to be ‘air-tight’ and produce thermal bridge-free junctions, the incorporation of fixings (normally plastic or metal) which penetrate the insulation layer, would result in a series of point repeating thermal bridges. With this in mind, special thermodowel fixings (Ã-value of no more than 0.002W/K) were utilised as part of the system and enabled the U-value and heating demand of the building not to be increased. Work began on a design that applied low-energy, low-carbon ‘design rules of thumb’ and it was hoped that a energy demand of no more than 22k Wh/m².yr would be possible. The end result is an ‘exemplar’ project in terms of the energy and thermal performance which can be achieved through retrofitted measures. Pre EWI installation Aesthetically, PermaRock’s Silicone K1.5 mm Finish throughcoloured render was used. Post EWI installation 19 04 Case Studies Award Winning Non-Traditional Housing Refurbishment: BISF Houses, Shirehampton, Bristol Client: Bristol City Council Specifier: Bristol City Council Substrate: BISF Steel Frame with plywood sheathing System: PermaRock 80 mm Mineral Fibre External Wall Insulation System Wall U-Value Achieved: 0.35 W/m²K System Finish: PermaRock Acrylic K 1.5 mm & Brick Effect Render Finishes Following a structural survey the consulting engineers advised the client that the best solution to increase the properties useful lifetime and thermal performance was to overclad the houses with an external wall insulation system. Technically, the properties could not be directly overclad with a ewi system and the existing cladding had to be removed and replaced with 18 mm exterior grade plywood to create a surface suitable for the application of the PermaRock external wall insulation system. The incorporation of 80 mm of fire-safe mineral fibre insulation within system enabled the required U-value to be achieved and the use of PermaRock’s Brick Effect Render (ground floor) & K 1.5 mm (first floor) decorative finishes helped achieve the upgraded aesthetic appearance which was being sought. Various other improvements (new windows, canopies, downpipes gutters) were also undertaken prior to or at the same time as the external wall insulation application to upgrade the properties to a ‘Decent Homes Standard’. The client chose to install a PermaRock mineral fibre external wall insulation (ewi) system which not only protected the existing building fabric but also enabled the thermal performance of the properties to be brought into line with Building Regulations at the time (0.35 W/m²K). A further benefit from the application was that it allowed the client to give the properties a more ‘traditional’ aesthetic look Pre EWI installation 20 Post EWI installation Award Winning Non-Traditional Housing Refurbishment: Steane Houses, Bournemouth Client: Bournemouth Borough Council Specifier: Curtins Consulting Substrate: PRC Panels with plywood sheathing System: PermaRock 70 mm Mineral Fibre External Wall Insulation System Wall U-Value Achieved: 0.35 W/m²K System Finish: PermaRock Acrylic K 1.5 mm and Brick Effect Render Finishes After assessing the structural integrity of the properties the consulting engineers decided the best approach to modernising the 50 dwellings was to apply a PermaRock external wall insulation system. The system would not only improve the aesthetics and thermal performance of the dwellings, it would also extend the life of the properties by a minimum of 30 years, a key concern for the client. Pre EWI installation Prior to the installation of the system, the existing PRC panels were removed, replaced with 18mm plywood and the existing steel frame was reinforced with a timber frame. These measures increased the load bearing properties of the walls to accommodate the external wall insulation system as the existing PRC panels were both cracked and corroded. Through the installation of a PermaRock 70mm mineral fibre external wall insulation system (where the tenants remained insitu), the external wall U-values were brought into line with current building regulations and provided the concrete panel houses with a more traditional look. PermaRock’s white acrylic through-coloured render was applied to the upper floors and PermaRock brick effect render to the lower floors. The client was so pleased with the results that PermaRock’s external wall insulation systems have been utilised on further non-traditional house types in the area. Post EWI installation 21 04 Case Studies Award Winning High-Rise Refurbishment: High-Rise Blocks, Glasgow Client: Glasgow Housing Association Specifier: Glasgow Housing Association & Wates Living Space Substrate: Large Concrete Panels (LPC) and No-Fines Concrete System: PermaRock 100 mm Mineral Fibre External Wall Insulation System Wall U-Value Achieved: 0.35 W/m²K System Finish: PermaRock Acrylic K 1.5 mm Finish A recent and on-going example of how PermaRock External Wall Insulation has improved energy efficiency and completely transformed the aesthetics of multi-storey high rise homes is demonstrated by the refurbishment programme being undertaken by Glasgow Housing Association (GHA) in conjunction with Wates Living Space. In excess of 40 towerblocks are either on site or completed to date, transforming what were typical rectangular concrete towers into an exciting new skyline. This constitutes one of the UK’s largest ever refurbishment programmes on multi-storey blocks, with 100 high-rise blocks being given a facelift over the coming years. In putting together a performance specification for the over-cladding systems for the GHA’s multi-storey residential blocks, careful consideration was given not only to the thermal performance requirements, in terms of improvements in the building envelope Uvalue, but also to fire resistance, resistance to impact, resistance to water penetration and wind suction forces. How the system installation could best be undertaken alongside a concurrent window replacement program was also taken into account. GHA, working closely with Wates Living Space, fully appreciated that the external envelopes of multi-storey, high rise buildings experience a wide range of unfavourable influences, such as extremes of temperature, wind, rain, fog, sunlight, atmospheric pollutants and the possibility of organic infestation from mildew, mould and algae. 22 There was also much thought given to the fire performance requirements for the external cladding system. Previous fires in high rise blocks at Knowsley Heights in 1991 and at Garnock Court, Irvine in 1999 had prompted revisions to the guidance on performance requirements for external cladding systems on multistorey buildings, and the GHA external cladding programme required that the cladding system be fully compliant with the Scottish Building Standards and tested in compliance with BS 8414-Part1: 2002 ‘Test method for non-loadbearing external cladding systems applied to the face of the building’ (Assessed in accordance with BR135). After a rigorous assessment of systems available in the UK, and after evaluating the technical support available from the system designers, as well as the experience and competencies of the systems approved installers, the PermaRock external wall insulation system was selected as a system that could meet all of the client’s requirements and comply with BS 8414-Part1: 2002. The results to date at Glasgow have met with approval from all quarters, and already the occupants of the blocks have noticed an improvement in internal comfort levels, as well as being delighted with the improvements in the appearance of their homes. Ian Morrison, of Whiteinch & Scotstoun HA (part of Glasgow HA), comments ‘With no investment in the external fabric of the building since the blocks were erected, tenants were delighted with the new windows and external cladding (PermaRock external wall insulation) works carried out. Tenants have generally expressed their relief that the buildings are now warm and can be heated more cost effectively, while the outward appearance of the block is now considered to be attractive. All at Whiteinch LHO were glad that working with our colleagues in the GHA could see these important improvements delivered to tenants’. The regeneration of the Glasgow high rise tower blocks clearly demonstrates how social housing can utilise the full capabilities of EWI. Not only are the basic technical requirements of structural protection and heat energy saving achieved, but the innovative use of bold colourful design indicates a level of excellence in a social housing refurbishment scheme. 23 05 CERT & CESP Supportive Funding PermaRock’s range of products and services is complimented by the ability to facilitate funding / grant support under the Carbon Emissions Reduction Target (CERT) and Community Energy Savings Programme (CESP) initiatives for residential external wall insulation (solid wall insulation) refurbishment projects. PermaRock, part of energy efficiency specialists Eaga plc is able to source funding contributions for the PermaRock external wall insulation element of a contract, subject to qualifying criteria. Carbon Emissions Reduction Target (CERT) What is CERT? CERT - which came into effect on 1 April 2008 and will run until 2012 - is an obligation introduced by the Government on energy suppliers to achieve targets for promoting reductions in carbon emissions in the household sector and combating fuel poverty. CERT will maintain a focus on vulnerable consumers and now includes new innovative and flexible approaches to energy efficiency, including PermaRock external wall insulation systems. What information is required? We would be pleased to investigate the opportunity to facilitate the potential provision of CERT funding for PermaRock External Wall Insulation schemes. To enable us to progress matters, we would need several items of information to calculate estimated values of any funding that might be available. The information required would be primarily: 1. The number of dwellings forming the scheme. 2. The type or types of dwellings (eg Flats, Semidetached, Terraced, etc). 3. Number of bedrooms in each type of dwelling. 4. The Postal Codes for the dwellings. 5. The existing and target U-Value in each case (note that PermaRock can assist with any necessary U-Value calculations that may be required if they haven’t already been prepared). 6. Current fuel type. 24 Furthermore, to qualify for any of the maximum levels of funding available, the social housing provider is required to sign a declaration (provided by us) stating that at least 70% of the homes are in “Priority Group” status, e.g. the homes are occupied by persons on qualifying benefits. CESP – Key Features • CESP will promote a whole house, house-by-house, street-by-street approach. Please contact PermaRock for further information on CERT funding. • It is estimated that up to 100 schemes will be funded, benefiting around 90,000 homes across Great Britain. Community Energy Savings Programme (CESP) • It will focus on low income areas. What is CESP? CESP is an initiative designed to help people to reduce their fuel bills and energy demand which aims to deliver around £350m of energy efficiency packages between autumn 2009 and December 2012. The programme has been developed to further encourage the use of innovative measures like external wall insulation, microgeneration, energy saving appliances and real time displays and aims to promote a ‘whole-house approach’ of energy reduction measures. CESP will be delivered through the development of community-based partnerships (involving local authorities) along with suppliers and generators. Thermal image post EWI installation • It will be delivered through the development of community-based partnerships involving Local Authorities. The following measures are included within CESP: External wall insulation Cavity wall insulation Loft insulation Loft insulation Internal wall insulation to solid wall housing Fuel switching Heating controls – upgrade with new heat system Community heating meters Existing community heat to CHP Electric to community CHP Wood pellet boilers (primary) Solar water heater (4mÇ) Air source heat pump Ground source heat pumps Micro wind (1 kWp, 1% LF) Mini-wind 5 kW, 20% LF Micro Hydro (0.7kWp, 50% LF) Photovoltaic panels (2.5 kWp) mCHP (revised) Replacing old boiler (65% by 88.3%) Home Energy Advice (HEA) Underfloor insulation Glazing E to C rated Flat roof insulation (whole house) Draughtproofing (ie not with glazing) • Under CESP, external wall insulation gets a CO2 lifetime savings ‘uplift’ bonus of 300%, making it as cost effective a measure per installation as both cavity and loft insulation in terms of kg CO2 score per £ spent. Incentives will also be given to encourage the whole-house approach, providing a ‘bonus’ for the delivery of multiple energy efficiency measures taken within the same property and to multiple properties within the same targeted area. Which areas qualify? It is proposed that CESP should target those areas of Great Britain that have significant levels of low income households. It is these areas that have the most dense concentration of households in need of assistance, and where energy efficiency improvements should have the greatest impact on fuel bills whilst also delivering carbon savings. The Government concluded that the use of Indices of Multiple Deprivation (IMD) would identify the most suitable areas for CESP. The Government proposes that SOAs (Super Output Areas) or Data Zones eligible for a CESP scheme must be within the lowest 10% income decile in England and the 15% most income deprived areas in Scotland and Wales, based on comparable level of income deprivation. PermaRock, in conjunction with our parent company, Eaga plc, (and Eaga’s partnerships with the CESP electricity generators and energy providers) can check potential eligibility on postcode verification, though please note eligibility does not automatically qualify for funding provision. 25 06 Systems Overview External Wall Insulation & Render Systems PermaRock offers a range of high quality products and systems that enable existing buildings to be refurbished or remodelled to improve both the thermal performance and to enhance the visual appearance. PermaRock’s façade products are equally suitable for high and low rise schemes and in sheltered or exposed situations. Technically, PermaRock systems insulate and reduce temperature variations within the structure, creating a stable internal environment and achieving the dual goals of maximising thermal performance and saving interior room space. They also reduce structural movement and protect, waterproof and preserve the fabric of the building. Aesthetically, PermaRock systems are complimented by an extensive range of decorative finishes including acrylic, silicone and mineral textured renders, brick and stone finishes, traditional spar dash aggregate finishes as well as architectural profiles and waterproof coatings which can dramatically improve the visual appearance of a building. The following groupings outline the principal brand ranges offered by PermaRock. External Wall Insulation Systems PermaRock’s range of render protected external insulation systems are designed to provide significant improvements in the thermal performance of buildings in both new-build and refurbishment applications. PermaRock Phenolic System The PermaRock Phenolic System is a high thermal resistance, low-profile rigid phenolic foam insulation board system. The high thermal resistivity of phenolic foam insulation enables a high level of thermal performance to be achieved for thin sections of insulation and the system is extremely versatile. It is suitable for application onto existing buildings, both high-rise and low-rise, and for most construction types including solid and cavity wall construction, timber and metal frame. On multi-storey buildings Phenolic EWI systems may require the incorporation of fire breaks in accordance with BRE Defect Action Sheet 131 and BRE 135-Second Edition. PermaRock EPS / EPS-Premium Systems The PermaRock EPS and EPS-Premium Systems are lightweight, low density systems employing expanded polystyrene insulation. The low density of the system makes it especially suitable for situations where low imposed loads are critical and is suitable for most construction types on multi-storey buildings. EPS systems may require the incorporation of fire breaks in accordance with BRE Defect Action Sheet 131 and BRE 135-Second Edition. EPS-Premium is a low conductivity EPS insulant which is particularly suited for super-insulated buildings. Exterior Render Systems A range of high performance exterior renders that offer levels of weatherproofing and crack resistance unmatched by conventional cement-based render technology. PermaRend System PermaRend is the leading brand of high impact resistant, polymer-modified cementitious renders. The basic PermaRend system is a two coat, thin render system (up to 5 mm per layer) that provides a tough, durable, lightweight and flexible alternative to traditional sand-cement renders. In addition to being highly resistant to impact damage, PermaRend renders are weatherproof, waterproof and water vapour permeable, allowing structures to breathe. PermaRend renders can be decoratively finished in any of PermaRock's extensive range of acrylic, silicone or silicate renders / plasters, mineral aggregate renders, silicone paints, stone chip coatings as well as with tile finishes and brick and stone effects. PermaRend Scratch Render is a high quality textured render based on natural limestone sand that can be used to provide a naturally textured ‘scraped’ finish or to create traditional stone effects including rustication, ashlar and simulated blockwork. Scratch Render is available in a range of natural shades and can be produced in special colours to order, subject to minimum order requirements. PermaRock’s range of systems for the refurbishment sector are based on three key insulation types and include: PermaRock Mineral Fibre System The PermaRock Mineral Fibre External Wall Insulation System incorporates fire-safe mineral fibre insulation boards. The system is extremely versatile and is suitable for use on existing buildings, both high-rise and lowrise, and for all construction types including solid and cavity wall construction, timber and metal frame, and non-traditional house types. The system is particularly suited to residential buildings (especially high-rise) and public buildings where the highest levels of fire resistance and non-combustibility are required and where the added acoustic noise reduction properties of mineral fibre insulation are of benefit. 26 Mineral Fibre System Phenolic System EPS System PermaRend System 27 06a Mineral Fibre EWI System System Comparison Table Mineral Fibre System Technical Data The system comparison chart below has been created to assist in product selection.

PermaRend is the leading brand of high impact-resistant, polymer-modified cementitious renders. The basic PermaRend system is a one, two or three coat, thin render system that provides a tough and durable, lightweight and flexible alternative to traditional sand-cement renders. PermaRend is a high impact-resistant, polymermodified, cement-based render containing performance improvers. PermaRend is designed to withstand water penetration whilst allowing water vapour diffusion, and is suitable for geographical areas including those classified as having very severe exposure to wind driven rain (BS 5628: Part 3 and BS 8104). PermaRend Scratch Render is a silicone based thick coat render with a scraped or scratch textured surface that is also suitable for the creation of simulated blockwork, ashlar detailing, etc. The range of products and systems available from PermaRock provides the specifier with individually tailored solutions that satisfy both the technical requirements of the substrate and the aesthetic requirements of the client. All of the products described provide effective resistance against water penetration whilst allowing the passage of water vapour, allowing walls to ‘breathe’. The incorporation of reinforcing mesh into systems provides additional resilience and resistance to cracking, and the use of mechanical fixing methods enables these products to be applied over existing render or painted surfaces where the reliance on an adhesive bond alone would be insufficient to guarantee performance. PermaRend systems are suitable for application onto new or existing brickwork, blockwork, dense and nofines concrete. PermaRend systems incorporating a lightweight reinforcement and mechanical fixings can be applied over existing render surfaces. PermaRend renders exhibit superb adhesion and ease of application by trowel or machine. PermaRend renders can be decoratively finished in any of PermaRock's extensive range of acrylic, silicone or silicate renders / plasters, mineral aggregate renders, silicone paints, stone chip coatings as well as with tile finishes and brick or stone effects. Supplied prepacked as a dry powder premix, PermaRend requires only the addition of clean water on site. The mixed render is applied by machine or trowel. PermaRend is suitable for all masonry and mineral substrates. However, surfaces should be of a good standard, ideally of fair-faced quality, and true to line, level and plumbness to avoid the need for preliminary levelling or dubbing out at extra cost. For application to existing masonry surfaces, the PermaRend system is enhanced by the incorporation of reinforcing mesh giving improved resistance to structural movement and providing a higher level of tensile strength. PermaRend Scratch Render is weatherproof and breathable, and incorporates special additives that confer water repellency to the surface, ensuring excellent self cleaning and resistance to dirt pick-up. In addition to the standard range of colours, described in our decorative finishes section, PermaRend Scratch render can be manufactured to customers individual shade requirements, subject to minimum order restrictions and the limitations of natural mineral pigmentation processes. PermaRend Exterior Scratch System On existing rendered surfaces or old surfaces that are weak or friable, mechanical dowel fixings are utilised through the reinforcing mesh to enhance the integrity of the system and to give a failsafe bond to the underlying substrate. PermaRend Exterior Render System Incorporating Through-Coloured Render Finish Bedding Mortar Reinforcement Bedding Mortar Primer Mechanical fixings are available for all substrate types. PermaRend renders can accept any of the extensive range of decorative finishes and effects available from PermaRock, including brick and stone finishes, acrylic and silicone textured renders and stone chip coatings. All PermaRend systems come complete with a fully comprehensive set of corner and edge protection profiles and trims, in stainless steel, polyester powder coated aluminium or pvc, as well as with sealing strips, mastics and tapes to enable robust and weathertight detailing to be achieved at windows, doors and abutments. Decorative Finish Cills, profiles and fixings have been omitted for clarity and are subject to project specification(s). 40 41 06e Environmental Profiling Environmental Profiling Ecopoints Greener Supply And Recycling In recent years there has been an increasing interest on the part of the specifier to understand more about the sustainability of building materials and the environmental impacts of products and materials utilised in the built environment. To improve the usefulness of the environmental data and make it easier to understand, the BRE developed Ecopoints ratings – a method of ranking and scoring different environmental impacts. PermaRock has an ongoing programme of waste management and reduction initiatives to minimise waste as well as providing the opportunity of recycling of system components. Examples of key benefits to using PermaRock systems are: Using methodology developed by the BRE (Building Research Establishment) and BERR (The Department for Business, Enterprise and Regulatory Reform), PermaRock commissioned third-party whole Life Cycle Assessments (LCA) on two of its key external wall insulation systems. The LCA measures the environmental impacts of the systems during their economic life, from the extraction of the raw materials and components to the disposal of the product at the end of a 60 year life cycle (i.e. cradle to grave). The environmental impact is determined by 12 categories, including Climate Change, Acid Depletion, Ozone Depletion, Pollution to Air, Pollution to Water, Mineral Extraction and Waste Disposal. The data obtained from the LCA is then analysed and weighted, using the BRE methodologies, and an Ecopoints rating for each system has been established. The lower the Ecopoints score, the lower the environmental impact. The results achieved by PermaRock are very impressive, estimated Ecopoints scores of 0.10 per m2 (1) and 0.15 per m2 (1) on PermaRock’s Mineral Fibre External Wall Insulation System and Phenolic External Wall Insulation Systems respectively were achieved. Such extremely low Ecopoints scores reflect the extensive work that PermaRock has put in to environmentally engineering its products, including reducing the energy costs associated with sourcing and transporting raw materials, manufacturing the products themselves, and delivering the products to construction sites throughout the UK. Significantly, PermaRock’s drive towards the incorporation of recycled content into its products has also had a beneficial impact on the Ecopoints score. To put the results into context, assessments have also been made on other construction products: For example a traditional brick cavity wall construction achieves a score of 0.48 per m2. • Greener Supply: Ongoing efforts are being made to reduce packaging waste. PermaRock are also looking at other in-house initiatives to reduce waste for raw materials and recycling as well as liaising with installers and project teams to produce improved workable solutions. • Insulation: Insulation boards are CFC (chlorofluorocarbons) and HCFC (hydrochlorofluorocarbons) free and they have zero ozone depletion potential (zero-ODP) and/or zero global warming potential (GWP). • Recycling: Recycling of certain insulation materials is now available. • Energy Saving Trust Approved Products: PermaRock systems are also listed on the EST site, www.energysavingtrust.org.uk, confirming that PermaRock systems are amongst the most energy efficient in their category. (1) PermaRock systems have been externally assessed using the environmental profile methods prescribed by the BRE 1999 and 2000 & likely Eco points calculated as per the BRE publication of 2001 42 43 06f System Components Pre-Application Decorative Finishes PermaRock Moss & Mould Remover Anti-fungal solution to treat surfaces infested with moss, mould, algae and the like.
