Lining Boards (External Applications)

Polyurethane (PUR) and Polyisocyanurate (PIR) insulation products, when used externally on solid wall constructions, offer one of the thinnest solutions available as a with superior thermal performance. By using these products, the emergency efficiency of a building can be easily and economically improved without sacrificing valuable internal floor area.

The PIR/PUR insulation products are mechanically fixed to an existing wall behind a traditional or lightweight polymer modified render system or fixed behind timber counter battens behind rendered expanded metal/cementitious board.

Whilst man-made-mineral-fibre (MMMF) is susceptible to water penetration, this can have a severe affect on its thermal performance, PIR/PUR insulation products are resistant, as a result of their closed cell structure, to moisture penetration. Consequently the thermal performance of PIR/PUR insulation products should remain at its designed level for the lifetime of the building.

Benefits of PIR/PUR insulation for External Applications:

• Superior thermal performance;
• Minimal cold bridging
• Does not settle and leave part of the wall un-insulated;
• Constant thermal performance for lifetime of the building;
• Eliminates the risk of water penetration;
• Are resistant to moisture ingress;
• Are non-fibrous and do not emit harmful emissions;
• Does not support the growth of fungi.
