2 Introduction Design Service Energy efficiency is key to many aspects of economic, energy, environmental and social policy objectives. Buildings have the biggest role to play as they consume more energy than any other sector. They account for 40% of Europe s energy use and a third of its greenhouse gas emissions (European Commission, Energy Efficiency in Buildings). The comprises of two elements: panels and flex infill strips. It comes with a supporting installation design service which ensures the ratio of panels to flex infill strips for each project is maximised. To reduce the energy demands of our buildings, increased thermal insulation must become a priority. Regulations reflect this by requiring increasingly higher levels of thermal insulation in the building envelope. But increasing insulation levels will lead to more complicated, deeper constructions and a loss of space unless we can find new ways to construct today s buildings in anticipation of tomorrow s demands. The solution is, the latest next generation innovation from Insulation. marked the advent of the next generation of insulation; takes this one step further with the introduction of a completely encapsulated vacuum insulation panel. comprises of an optimum performance panel, encapsulated in a high performance PIR insulation board to provide complete protection to the during the installation and construction processes. With a thermal conductivity (λ) of W/m.K, the panels provide an insulating performance that is up to three times better than commonly used insulation materials.

3 Typical Constructions and U values Assumptions The U values in the tables that follow have been calculated, under a CERTIFICATE CS/ management system certified to the BBA U Value Competency Scheme Scheme for Assessing the Competency of Persons to Undertake U value and Condensation Risk Calculations, using the method detailed in BS / I.S. EN ISO 6946: 2007 (Building components and building elements. Thermal resistance and thermal transmittance. Calculation method) and using the conventions set out in BR 443 (Conventions for U value calculations). They are valid for the constructions shown in the details immediately above each table. These examples are based on waterproofed using a cold liquid applied system or using a fully adhered single ply membrane. The insulation panel is fully bonded to the type of deck stated for each application or a vapour control layer, which has itself been fully bonded to the type of deck stated for each application; the ceiling, where applicable, is taken to be a 3 mm skim coated 12.5 mm plasterboard with a cavity between it and the underside of the deck. NB For the purposes of these calculations the standard of workmanship has been assumed good and therefore the correction factor for air gaps has been ignored. NB The figures quoted are for guidance only. A detailed U value calculation together with condensation risk analysis should be completed for each individual project. NB If your construction is different from those specified and / or to gain a comprehensive U value calculation along with a condensation risk analysis for your project please consult the Insulation Technical Service Department for assistance (see rear cover). NB For the purposes of these calculations the bridging effect of the flex has been taken to be 20%. For accurate calculations a design will be required and the bridging effect may change the U values shown.

6 Design Considerations Linear Thermal Bridging Reasonable provision must be made to limit the effects of cold bridging. The design should ensure that roof light or ventilator kerbs etc. are always insulated with a 25 mm thick flex strip. A 25 mm thick flex upstand should be used around the perimeter of the roof on the internal façade of parapets. A minimum distance of 300 mm should be maintained between the top of the insulation upstand and the bottom of the horizontal roof insulation. Wall insulation should also be carried up into parapets as high as the flat roof insulation upstand. Please contact the Insulation Technical Service Department (see rear cover) for further advice. Responsible Sourcing is manufactured under a management system certified to BS / I.S. EN ISO 14001: The principle polymer components of the product are also manufactured under management systems certified to EN ISO 14001: NB The above information is correct at the time of writing. Please confirm at the point of need by contacting Insulation s Technical Service Department (see rear cover), from which copies of Insulation and its suppliers ISO certificates can be obtained. Sustainability & Responsibility Insulation has a long term commitment to sustainability and responsibility: as a manufacturer and supplier of insulation products; as an employer; as a substantial landholder; and as a key member of its neighbouring communities. A report covering the sustainability and responsibility of Insulation Ltd s operations at its Pembridge, Herefordshire and Selby, North Yorkshire manufacturing facilities is available at Specification Clause should be described in specifications as: The roof insulation shall be the mm thick comprising a rigid vacuum insulation panel with a microporous core which is evacuated, encased and sealed in a thin, gas tight envelope, encapsulated in a high performance rigid thermoset insulation, faced on both sides with a coated glass tissue facing. The thermoset insulation component of the product shall be manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP); in accordance with the requirements of BS and BS NBS Specifications Details also available in NBS Plus. NBS users should refer to clause(s): J21 420, J21 430, J (Standard and Intermediate) J21 10 (Minor Works) Wind Loading Wind loadings should be assessed in accordance with BS : 1997 (Loadings for buildings. Code of practice for wind loads) or BS / I.S. EN : 2005 (National Annex to Eurocode 1 Actions on Structures. General Actions. Wind Actions) taking into account: l length / width / height of the building; l orientation of the building; l wind speed; l aspect (e.g. on a hill side); and l topographical value of the surrounding area. Falls The fall on a flat roof, constructed using, is normally provided by the supporting structure being directed towards the rainwater outlets. The fall should be smooth and steep enough to prevent the formation of rainwater ponds. In order to ensure adequate drainage, BS 6229: 2003 (Flat roofs with continuously supported coverings. Code of practice) recommends uniform gradients of not less than 1 in 80. However, because of building settlement, it is advisable to design in even greater falls. These can be provided by the when used with an overlay of Thermataper LPC/FM tapered (see below). Tapered Roofing can also be used in a tapered roofing scheme. The scheme comes with a supporting design service. This ensures that the most cost effective solution for a roof is identified and that the end result is a tapered system design which meets a roof s rainwater run off and insulation requirements. Further details are available from the Insulation Tapered Roofing Department (see rear cover), which should be consulted as early as possible in the process of designing a roof. The product shall be manufactured under a management system certified to BS / I.S. EN ISO 9001: 2008, BS / I.S. EN ISO 14001: 2004 and BS / I.S. OHSAS 18001: 2007; by Insulation Limited; and installed in accordance with the instructions issued by them. 6

7 Roof Waterproofing is suitable for use with most fully adhered single ply waterproofing membranes. When using with fully adhered single ply waterproofing membranes, the joints between boards immediately below the waterproofing membrane, must be taped with a min. 50 mm wide foil tape. Please contact the Insulation Technical Service Department (see rear cover) to check waterproofing membrane and proprietary adhesive system compatibility. Advice should be sought, from the appropriate waterproofing membrane manufacturer, in relation to the requirement for the use of a fleece backed membrane with the waterproofing membrane in question. is suitable for use with most cold liquid applied waterproofing systems. When using with cold liquid applied waterproofing systems, a carrier membrane for the waterproofing must be installed over the insulation boards. Advice should be sought, from the waterproofing system manufacturer, about the specification of the carrier membrane and the compatibility of the waterproofing system with. For further advice please contact the Insulation Technical Service Department (see rear cover). Water Vapour Control should be installed over a separate vapour control layer in new build roofs. Regardless of the deck type it is recommended that a condensation risk analysis is carried out for every project. For refurbishment projects, involving the addition of insulation to existing insulated flat roofs, or roofs constructed of insulated steel faced composite panels, it is imperative that a U value calculation and condensation risk analysis is carried out for every project, in order to ensure that the correct thickness of insulation is installed to achieve the required thermal performance, whilst avoiding interstitial condensation. In refurbishment projects, where is to be installed over an existing bituminous waterproofing membrane, the membrane can be used as a vapour control layer, as long as it is in a good water tight condition. Where this is not the case, a separate vapour control layer should be installed. Where the separate vapour control layer is to be bonded, allowance should be made for adequate bonding of the vapour control layer to the substrate, so as to provide a suitable surface upon which to lay the insulation boards and sufficient resistance to wind up lift (see Wind Loading ). Roof Loading / Traffic is suitable for use on access roof decks subject to limited foot traffic. Where inappropriate foot traffic is liable to occur, it is recommended that, for roofs waterproofed with fully adhered single ply or cold liquid applied waterproofing systems, the roof surface is protected by specially constructed walk ways. For further advice on the acceptability of specific foot traffic regimes, please contact the Insulation Technical Service Department (see rear cover). Green Roofs is suitable for use under most green roof systems. Green roof systems are a specialist design area. When designing a loose laid insulated green roof assembly consideration needs to be given to the following. Green roof systems are required to have a minimum dry weight of 80 kg/m 2 to ballast the insulation boards beneath them. However, the total required dry weight will depend upon wind uplift, which in turn will vary with the geographical location of the building, local topography, and the height and width of the roof concerned. The necessity for any additional dry weight should be assessed in accordance with BS : 1997 (Loading for Buildings. Code of practice for wind loads) or BS / I.S. EN : 2005 (National Annex to Eurocode 1 Actions on structures. General Actions. Wind Actions). When installing a loose laid insulated green roof assembly, any insulation must be immediately over laid with the green roof system, which must meet all of the requirements outlined above. Where these requirements cannot be ensured, the insulation must be bonded down (see Sitework). For further information please contact the Insulation Technical Service Department (see rear cover). For applications where the insulation boards are to be bonded to the vapour control layer, a minimum vapour control layer should consist of a coated roofing felt complying with Type 3B to BS 747: 2000 (Reinforced bitumen sheets for Roofing. Specification), or S1P1 to BS 8747: 2007 (Reinforced bitumen membranes (RBMs) for roofing. Guide to selection and specification), or any appropriate metal cored vapour control layer. 7

8 Sitework Installing over Metal Decks l Metal decks should be clean, dry, without large projections, steps or gaps, and should be graded to allow correct falls to all rainwater outlets. l In order to ensure an adequate bond between the metal deck and the vapour control layer, the metal deck should be suitably primed, in accordance with the primer manufacturer s instructions, prior to the application of the hot bitumen, or suitable alternative proprietary adhesive system, used to bond the vapour control layer to the deck. l Where one run of the specified vapour control layer laps another, there should be minimum 150 mm side and end overlaps, which should be adequately sealed. l Turn up the vapour control layer at the edge of the roof to a height appropriate to the specified waterproofing membrane. l should be bonded down with the use of a suitable proprietary adhesive system over the vapour control layer. l Insulation boards should always be laid in accordance with the scheme diagram provided. Break bonded, either with their long edges at right angles to the trough openings, or diagonally across the corrugation line, and with joints lightly butted. There should be no gaps at abutments. l At the perimeter of the roof and where upstands or any other penetrations (e.g. roof lights or ventilator kerbs) are present, flex infill strips should be laid abutting these areas, in strips no less than 200 mm wide, to take account of building tolerances and to provide a zone to allow for peel restraint mechanical fixing of the membrane should it be required. Refer to the waterproofing manufacturer for guidance on appropriate peel restraint detailing. l A 25 mm thick flex upstand should be used around the perimeter of the roof on the internal façade of parapets. l A minimum distance of 300 mm should be maintained between the top of the insulation upstand and the bottom of the horizontal roof insulation. l The waterproofing membrane is installed in accordance with the membrane manufacturer s instructions, over the whole insulated area including any insulation upstands, as soon as possible after laying the insulation boards. Installing over Concrete Decks l Concrete decks should be clean, dry, without large projections, steps or gaps, and should be graded to allow correct falls to all rainwater outlets. l In order to ensure an adequate bond between the vapour control layer and the concrete deck, the concrete or screeded surface should be suitably primed, in accordance with the primer manufacturer s instructions, prior to the application of a suitable proprietary adhesive system, used to bond the vapour control layer to the deck. l Where one run of the specified vapour control layer laps another, there should be minimum 150 mm side and end overlaps, which should be adequately sealed. l Turn up the vapour control layer at the edge of the roof to a height appropriate to the specified waterproofing membrane. l should be bonded down with the use of a suitable proprietary adhesive system over the vapour control layer. l Insulation boards should always be laid in accordance with the the scheme diagram provided.

10 Sitework Installing over Existing Composite Panel Roofs l If the existing profile provides inadequate support for the insulation boards, the existing roof should be over boarded, e.g. with plywood, prior to their installation. l Insulation boards should always be laid break bonded and with joints lightly butted. There should be no gaps at abutments. If the existing roof has been over boarded, then insulation boards should be laid with their long edges at right angles to the edge of, or diagonally across the roof. If not, they should be laid either with their long edges at right angles to the trough openings, or diagonally across the corrugation line. l At the perimeter of the roof and where upstands or any other penetrations (e.g. roof lights or ventilator kerbs) are present, flex infill strips should be laid abutting these areas, in strips no less than 200 mm wide, to take account of building tolerances and to provide a zone to allow for peel restraint mechanical fixing of the membrane should it be required. Refer to the waterproofing manufacturer for guidance on appropriate peel restraint detailing. l The waterproofing membrane is installed in accordance with the membrane manufacturer s instructions, over the whole insulated area including any insulation upstands, as soon as possible after laying the insulation boards Installing in Two Layers l In situations where two layers of insulation are required (e.g. two layers of panels or when an overlay is used), both layers should be installed in the same manner, as detailed in the preceding sections. l In all cases, the layers should be horizontally offset relative to each other so that, as far as possible, the board joints in the two adjacent layers do not coincide with each other (see Figure 6) or as detailed on the design scheme provided. First insulation layer General Following Trades l The roof must be adequately protected when building works are being carried out on or over the roof surface. This is best achieved by close boarding. The completed roof must not be used for storage of heavy building components such as bricks or air conditioning equipment. Daily Working Practice l At the completion of each day s work, or whenever work is interrupted for extended periods of time, a night joint must be made in order to prevent water penetration into the roof construction. Cutting l panels should not be cut or penetrated. l The substrate must be clean, dry and level, and free of sharp objects or edges. l Cutting of the flex infill strips should be carried out either by using a fine toothed saw, or by scoring with a sharp knife, snapping the board over a straight edge and then cutting the facing on the other side. l Ensure accurate trimming of the flex strips to achieve close butting joints and continuity of insulation. Availability l Please contact Insulation for availability of the. Packaging and Storage l The packaging of Roofing System should not be considered adequate for outdoor protection. The Roofing System should be stored inside a building and raised off the floor. Health and Safety l Insulation products are chemically inert and safe to use. l A Safety Information Data Sheet for this product is available from the Insulation Technical Service Department. Warning do not stand on or otherwise support your weight on this board unless it is fully supported by a load bearing surface. Second insulation layer, if required, offset relative to first.
