2 Introduction The Problem When constructing a wall in new build situations or upgrading the thermal performance of walls in existing buildings there may be a requirement for both low U values and the thinnest possible wall build up. For new build applications, there are increasing regulatory requirements and economic reasons to improve energy efficiency. One of the more efficient approaches is to improve the thermal performance of the building fabric whilst keeping the overall construction as thin as possible. There are already high performance insulation products available that will fulfil some of these requirements, however in certain areas, for example where the design requirements are such, a new, thinner, product is needed. In refurbishment there is arguably a greater need to keep wall build ups as thin as possible. Space is already at a premium and there may be little space for installing new external wall insulation, for example because of the available depth of eaves overhangs, encroachment into access routes and the creation of unsightly steps between adjacent insulated and uninsulated walls. Greater thicknesses of external wall insulation could necessitate extending eaves, longer and more costly fixings, trims and accessories, and may result in greater reveal depths, reducing natural daylight. The Solution The External Wall System has been developed to help solve these problems. The External Wall System is an optimum performance next generation insulation solution from Insulation. It comprises rigid vacuum insulation panels with a microporous core which is evacuated, encased and sealed in a thin, gas tight envelope, giving outstanding thermal conductivity, and providing the thinnest possible solution to insulation problems. The vacuum insulation panels are accompanied by premium performance rigid insulation infill panels which can be cut to fit around penetrations, reveals and where fixtures and fittings need to be installed. In retrofit applications, the External Wall System provides solutions for areas that previously could have remained un insulated because of insufficient space available. In new constructions the External Wall System can significantly enhance U values in areas that would otherwise be accepted as denigrating the overall thermal performance. With a declared thermal conductivity (λ) of W/m.K, the panels provide an insulating performance that is up to five times better than commonly used insulation materials. 2

3 Typical Constructions and U values Assumptions It is advisable to contact the Insulation Technical Service Department (see rear cover) for specific U value calculations. All calculations are performed using the method detailed in BS EN ISO 6946: 2017 / I.S. EN ISO 6946: 2007 (Building components and building elements. Thermal resistance and thermal transmittance. Calculation methods), and using the conventions set out in BR 443 (Conventions for U value calculations).

4 Typical Constructions and U values Refurbishment 100 mm Brick / 50 mm Cavity / 100 mm Brick Wall fix strips Render system incorporating EML or glass fibre mesh 13 mm dense plaster Linear Thermal Bridging at Junctions Basic Principles Linear thermal bridging describes the heat loss / gain that occurs at junctions between elements e.g. where an external wall meets the roof, or at junctions around openings in the building fabric where thermal insulation is discontinuous e.g. sills, jambs and lintels. Interruptions within the insulation by materials with poorer insulating properties can result in a thermal bridge, which can lead to problems of condensation and mould growth, especially if there is a drop in surface temperature. Render carrier board (magnesium silicate) Brick slips on carrier track * Refer to Sitework Figure 4 Solid Brick Wall fix strips Render system incorporating EML or glass fibre mesh Render carrier board (magnesium silicate) Brick slips on carrier track * Refer to Sitework Figure 5 Levelling compound* 13 mm dense plaster Levelling compound* The heat flow at these junctions and opening locations, over and above that through the adjoining plane elements is the linear thermal transmittance of the thermal bridge: measured in W/m.K; referred to as a psi value ; and expressed as a ψ value. The lower the ψ value, the better the performance. ψ values are taken into account in the calculation methodologies e.g. Standard Assessment Procedure (SAP) that are used to assess the operational CO 2 emissions and the fabric energy efficiency of new buildings. ψ values can comprise approved, calculated or assumed values. Existing building junction losses are not typically accounted for in whole building heat loss calculations and only the risks of surface condensation and mould growth are considered. Reducing Linear Thermal Bridging Heat typically flows through the easiest path. For a wall insulated with the External Wall System the main linear thermal bridges are the reveals, the junction between the walls and the roof and where the external wall and ground floor meet. Whilst there are some approved details available for External Wall Insulation (EWI), they are largely targeted at new build constructions. However, they are also considered good practice for refurbishment. Continuity of insulation is the best approach to limit losses through junctions. Failing continuity, overlap of insulation layers and use of lower conductivity materials represents a good practice approach. However, where neither option is possible, the risk of condensation will require particular consideration in determining an appropriate approach. Details and designs should be considered in the context of the property, its construction, characteristics, condition and ventilation provisions. Detailing at junctions to minimise the effects of thermal bridging and the associated risk of condensation or mould growth is important and there are some simple design considerations that can be adopted when insulating to help mitigate the risks and to reduce heat loss. 4

5 l The reveal linear thermal bridge can be minimised either by positioning the window frame so that its outer face is flush with the outer surface of the masonry wall, and overlapping the window frame with the external wall insulation. Or, if this is not possible, by insulating the reveal at jambs, head and sill. The key factor is the thermal resistance (R value) of this insulation layer. l Reveals should be designed to accommodate the 20 mm flex strips required to achieve an R value of 0.6 m 2. K/W (see Figure 6). l Heat loss through reveal junctions can also be reduced by internally accommodating 32.5 mm (min.) of Kooltherm K118 Insulated Plasterboard around the openings. l Where existing windows or doors are not replaced as part of renovation works, design and detailing should consider the potential for future replacement works. l At ground floor junctions where the External Wall System is used on an existing substrate, good practice is to extend the insulation below the starter rail as an insulated plinth to ground level (for example using Purlcrete chevron). Best practice would be to excavate and extend the external insulation below ground level by at least 300 mm below finished floor level to increase the heat flow path and reduce junction losses. A starter rail/track formed from a low conductivity material can also help to reduce losses through this junction. l For a new build construction, where the External Wall System is used to sheath a frame construction at the edge of ground floors, the distance between the top surface of the floor insulation or perimeter insulation upstand, and the bottom of the wall insulation must be a minimum of 150 / 225* mm for a concrete floor and 200 mm for a suspended timber floor. The further appropriate wall insulation extends past the floor insulation, the better the thermal performance of the junction between the wall and the floor will be. l At junctions with roofs, the External Wall System has an advantage over other systems, in that the overall reduced thickness of the system may be accommodated within the existing eaves and gables overhang. This can avoid the necessity of either a step out from the eaves at the wall insulation, or for extending the roof eaves or verge over the External Wall System. Loft insulation should overhang the externally applied insulation layer effectively to avoid a significant thermal bridge occurring. Best practice where the overhang is insufficient to accommodate the External Wall System is to extend the existing roof and to maintain continuity of insulation between the roof and walls. l Best practice is to reposition existing rainwater guttering and downpipes, maintaining continuity of insulation (and reducing losses from the junction) whilst also increasing robustness at interfaces to reduce the risk of water entering and damaging the External Wall System. l It is also important to consider other obstructions to the continuity of insulation, such as meter boxes, satellite dishes, flues, ventilation ducts and grilles, and gas and mains water connections. Best practice would be for these to be removed and re fixed to the surface of the external wall finish by appropriate persons/agencies to ensure continuity of insulation. l There will be instances where separation from flues / air ducts and combustible material is required and appropriate instructions and guidance should be sought and followed where applicable. For further advice on details to reduce linear thermal bridging please contact the Insulation Technical Service Department (see rear cover for details). * 150 mm applies to the UK and 225 mm to the Republic of Ireland.

7 Sitework Steel Frame with Insulated Sheathing l The External Wall System should be installed to the outside of the steel frame structure (outside of the backing board / sheathing). l The backing board / sheathing forming the face of the substrate against which the panels are installed should be clean, flat and free from protrusions. l The fix strips, minimum 100 mm wide, should be installed vertically at maximum 600 mm horizontal centres, coinciding with a vertical steelwork member, in order to provide a fixing point for the subsequent attachment of the channel with wall tie system, to tie the external masonry skin to the steel frame structure. Strips should be of the same thickness as the specified panels. The fix strips should be mechanically fixed back to the structure using appropriate mechanical fasteners, preferably thermally broken. l The panels should be installed between the fix strips with edges lightly butted. All panels are to be installed with the film flaps against the substrate. Remaining areas of wall around openings and other details which cannot be insulated with the panels should be in filled with an equal thickness of flex strips. l The panels should be restrained to the backing board / sheathing using a suitable proprietary adhesive. For further advice on the specification of the proprietary adhesive please contact the Insulation Technical Service Department (see rear cover), or refer to: Sika Limited (0) Fixfast Limited (0) l The flex strips should be mechanically fixed back to the structure using appropriate mechanical fasteners, preferably thermally broken. l Care should be taken to install the specified thickness of insulation around reveals (see Figure 6). l Once the panels, fix and flex strips have been installed, self-drilling screws are fixed through the channel and the fix strips, into the steel structure behind. Once the channel is installed, wall ties can be positioned at any point along its length and are built into the bed joints of the outer leaf of brickwork. l The spacing of ties is dependent on the type and height of the building and its geographical location. Advice should be sought from both the appropriate steel frame manufacturer and wall tie restraint system manufacturer. In the absence of any other guidance refer to: Ancon Building Products +44 (0)

8 Sitework Insulated Render Systems l Because insulated render systems are proprietary and utilise different mechanisms for attaching insulation to the wall structure, sitework guidance should be sought from the render system manufacturer. In the absence of any other guidance, the instructions laid out below may be followed. l The external masonry wall should be clean, flat, and free from protrusions. Where an uneven surface remains, it is recommended that a levelling compound be applied. l External wall insulation should start 150 / 200 / 600* mm below the top surface of the ground floor insulation / perimeter insulation upstand (whichever is higher) for a concrete floor, or 200 mm below the top surface of the ground floor insulation / perimeter insulation upstand (whichever is higher) for a suspended timber floor. * 150 mm applies to the UK. 200 mm applies to the Republic of Ireland if a row of insulating blockwork (thermal conductivity < 0.20 W/m. K) is used, otherwise 600 mm applies. l fix strips, minimum 100 mm wide, should be installed horizontally at maximum 600 mm vertical centres, in order to provide a fixing point for the subsequent attachment of the render carrier board which will accept the render finish or the carrier track which will accept the brick slip system. fix strips should be of the same thickness as the specified panels. fix strips should be mechanically fixed back to the substrate using appropriate mechanical fasteners, preferably thermally broken. l The panels should be installed between fix strips with edges lightly butted. All panels are to be installed with the film flaps against the substrate. Remaining areas of wall around openings and other details which can not be insulated with the panels should be in filled with an equal thickness of flex strips. l The panels should be restrained to the substrate using a suitable proprietary adhesive. For further advice on the specification of the proprietary adhesive please contact the Insulation Technical Service Department (see rear cover)), or refer to: Sika Limited (0) Fixfast Limited (0) l The flex strips should be mechanically fixed back to the substrate using appropriate mechanical fasteners, preferably thermally broken. l Care should be taken to install the specified thickness of insulation around reveals (see Figure 6). l Once the, fix and flex strips have been installed, a render carrier board is installed in a continuous layer over the assembly and fixed back to the substrate through the horizontal fix strips in order to accept the render finish. Alternatively a carrier track can be installed to accept a brick slip finish. l When selecting the type of fixing and fixing frequency, consideration must be given to the design of the wall and wind loading. For details on suitable fixings please consult the appropriate fixing manufacturer. Care must be taken to ensure fasteners do not penetrate the panels. l Wherever possible, care should be taken to avoid cold bridging when attaching services and ancillaries to the exterior of the building (see Figure 7). l Depending on the render finish being applied, advice must be sought from the render manufacturer on the Expanded Metal Lathing (EML) / glass fibre mesh and bedding mortar to be applied. l In refurbishment projects, sill extenders and flashings should be used around openings, with care taken to avoid cold bridging (see Figure 8). 8

9 Proprietary bracket fixings dependant on substrate flex strips General l The panels should not be used in association with solvent based adhesive systems. l The panels should not be exposed to naked flames or excessive heat.
