3.1 STRENGTH AND STABILITY The ParexLahabra EIF System can be designed to withstand the wind pressures (including suction) and thermal stresses in accordance with the Building Regulations 1997 to 2008. The system has adequate resistance to severe mechanical or malicious impact and abrasion where walls are exposed and have some protection, e.g. walls of private dwellings and walls of communal dwellings above ground floor level. The design should include for preventing impact from motor vehicles or other machinery. Preventative measures such as provision of protective barriers or kerbs should be considered. 3.2 DESIGN DATA The system is designed by Parex USA Inc. on a project specific basis in accordance with an approved design process. The installation of the system is by Parex USA Inc. approved and trained installers, and installation is monitored by Parex USA Inc. technical representatives. The design will include for: a) Preparation of substrate. b) Minimising risk of condensation in accordance with

the recommendations of BS 5250:2002 Code of practice for control of condensation in buildings.

c) Thermal insulation provision to Part L of the Building Regulations 1997 to 2008.

4.1 BEHAVIOUR IN RELATION TO FIRE Test to BS 476-6 and BS 476-7 show that the ParexLahabra EIF System is a Class 1 material in respect of surface spread of flame, which per Clause A12 of Part B of the Building Regulations 1997 to 2008, is Class 0 which is the highest product performance classification. With regard to fire stopping of cavities and limitations on use of combustible materials, walls must comply with Sections B3.2, B3.3 and B4 of TGD to Part B of the Building Regulations 1997 to 2008. The fixing design should take account of the extra duty required under fire conditions.

d) Resistance to impact and abrasion. e) Resistance to thermal stresses. f) Resistance to wind loading. g) Design of fixings to withstand design wind loadings. h) Design for fire resistance, fire spread and fire

stopping. i) Design of a water management system to prevent

ingress of water at movement joints, windows, doors, openings for services etc. Particular attention is required to ensure that window and window cill design are co-ordinated to achieve a fully integrated design.

j) Movement joints. k) A site specific maintenance programme. l) Durability requirements. Detailing and construction must be to a high standard to prevent ingress of water and to achieve the design thermal performance. Adequate provision should be made at design and installation stage for release of trapped moisture e.g. above window heads. When designed and installed in accordance with this Certificate, the system will satisfy the requirements of Part L of the Building Regulations 1997 to 2008. The design shall include for the elimination of cold bridging at window and door reveals, eaves, and at ground floor level. Care should be taken to ensure that any ventilation openings are not obstructed.

4.2 THERMAL INSULATION Assessments were carried out to verify that the requirements of Part L of the Building Regulations 1997 to 2008 can be achieved using the ParexLahabra EIF System. U-value calculations may be based on a thermal conductivity value of 0.038W/mK for the standard EPS insulation and 0.031W/mK for the carbon/graphite enhanced EPS. 4.3 CONDENSATION RISK The approved installer should identify areas where there is a significant risk of interstitial condensation due to high levels of humidity. Condensation risk analysis will be carried out by the Certificate holder in accordance with BS 5250:2002, and the design modified as appropriate to reduce the risk of surface condensation to acceptable levels.

4.4 MAINTENANCE Adequate provision should be made in the initial design phase, for access for inspection and maintenance over the life of the building. The system shall be inspected and maintained in accordance with the Certificate holder’s instructions. Repairs should be carried out in accordance with the Certificate holder’s method statement for inspection and repair. Repairs to plumbing etc. should also be carried out as required to prevent deterioration or damage, and to protect the integrity of the system. Synthetic finishes, including Parex DPR Standard Finish, may be subject to aesthetic deterioration due to exposure to ultraviolet light. They should be re-painted every 18 to 20 years to maintain appearance. Care should be taken to ensure that the paint used is compatible with the original system and that the water vapour transmission or fire characteristics are not adversely affected. Sealants shall be subject to regular inspection (at least annually). They should be replaced as required and fully replaced every 18 to 20 years to maintain performance. 4.5 DURABILITY 4.5.1 Design Life The ParexLahabra EIF System, when designed, installed and maintained in accordance with this Certificate, will remain effective for at least 30 years.
