1 Certificate No: EWWS546 Kingspan TEK Building System Description of Product Kingspan TEK Building System for use as wall and roof panels. The system is a structural insulated panel (SIP) system comprising of rigid urethane between OSB. Photo/isometric drawing provided by manufacturer Key Factors Assessed Mechanical Resistance & Stability Safety in case of Fire Hygiene, health and environment Protection against noise Energy Economy and heat retention Durability serviceability and identification Validity This certificate was first issued on 7th May 2015 and is valid until 7th May 2016 Issue Dated 7th May 2015

2 This registration system relates to Kingspan TEK building System. The panels are constructed using rigid urethane insulation between two layers of 15mm OSB/3. The panels are manufactured in overall thicknesses of 142mm and 172mm. The exposed panels achieve surface spread of flame of class 3 although this will be exceeded where suitable cladding and surface finish is applied. The panels are suitable for use as load bearing partitions, separating walls, the inner leaf of external walls and pitched roofs in dwellings up to four storeys high subject to provision of solid timber spline joints at ground floor level. The system may also be used as infill panels in multi-storey buildings subject to design constraints in height and method of fixing to the structural frame. All fixings must be designed to allow movement within the structural frame due to expansion/ contraction or differential movement. The panels are available in widths ranging from 200 mm to a maximum of 1220 mm, and lengths up to 7500 mm, and are supplied in the appropriate shapes and sizes for each project. The panels have a minimum service life of 60 years provided that they are protected from damage/weather prior to installation. Protection is achieved by the external and internal finishes. The anticipated working life of 60 years is subject to packaging, transport, storage and installation. Damaged panels should not be used or repaired. The indications of working life should be indicative rather than prescriptive as conditions on site are beyond the scope of the manufacturer. The panel assembly has been tested by Exova Warringtonfire see test report WF Fire Resistance Performance testing of load bearing wall assembly to BS EN 1365: achieving a 78 minute fire resistance period Compliance with the current requirements of L1A will be achieved and air leakage can be minimised by adherence to the manufacturers detailing and the relevant agrement certificate. The system has been approved through Robust Details for acoustic performance. Further individual details will be required when considering siting of heat producing appliances, flues and chimneys. The manufacturer shall exercise permanent internal control of products to ensure that a consistently high standard is achieved. Design, manufacture and installation should be carried out strictly in accordance with the requirements of ETA 11 /0466 for the product issued by BBA as demonstration of compliance with ETAG 019 Prefabricated wood-based loadbearing stressed skin panels. All panels should be loaded, transported, unloaded and stored in a suitable manner to reduce the risk of damage (Mechanical or weather). Installation/ erection should only be undertaken by persons who are trained and assessed to undertake this work and should be undertaken in accordance with details and construction drawings designed in accordance with the BBA Agrement Certificate holder s recommendations. Installed panels should be protected appropriately with a vapour-permeable membrane to EN 13859: 2010, prior to the addition of the final weather-proof construction materials. When used to construct walls and roofs the panels will normally be protected by internal and external finishes to prevent impact damage.

3 For LABC Warranty purposes: The making of openings for windows and doors in the SIP wall panels should be undertaken by either the factory or approved contractors following the manufacturer s details and a structural engineers design. The detailing at external window and door openings for resistance to damp penetration will be required to be approved on a job by job basis and not covered by this assessment. The SIP building system should be erected only by Kingspan approved Delivery partners. The wall panels and claddings / dpc s must meet the requirements of Chapter 7.3 of the Warranty Technical Manual. A residual cavity will be required with all Wall Cladding proposals. A suitable breather membrane & roofing must be provided to protect the SIP panels from water penetration through the claddings. Projects with Balconies or parapets are not covered by this assessment and will be required to be approved in advance by LABC Warranty on a job by job basis with a particular emphasis on how water penetration and rainwater disposal (through the panels) will be managed. The use of the SiP wall panels will be restricted for Warranty purposes to 4 stories in height (including the ground storey) Should any other wall ties be proposed that are not as recommended in the BBA Document, then the manufacturer should provide evidence they are suitable for use with their panel system. For Scotland purposes: That the specifications and materials referred to have been assessed and approved in accordance with the Building (Scotland) Regulations 2004 and in accordance with the supporting guidance in the Domestic Technical Handbooks which came into force with effect from 1 October That where reference is made on a plan or specification document to any Code of Practice, British or European Standard or manufacturer s instruction it shall be construed as a reference to such publication in the form in which it is in force at the date of this registered detail. That the materials specified shall not be changed without first gaining approval so to do. Failure to do so will invalidate the registered detail. This registered detail should not be regarded as a formal approval under the building warrant process prescribed by the Building (Scotland) Act 2003 enacted from 1 May 2005 That this Registered Detail shall contribute to compliance with relevant Standards specified under the Building (Scotland) Regulations 2004 as amended when read with the Limitations of Use Section to this Registered Detail.
