Insulation System for Flat Roofs & Balconies
XtraVIP Insulation System for Flat Roofs & Balconies is a rigid Vacuum Insulation Panel (VIP), consisting of a compressed, fumed, silica sand, microporous core which is evacuated of air and moisture before being
encased and sealed in a special thin, gas-tight, hybrid aluminium foil envelope. Encapsulated and protected within a robust two component elastomeric polyurea waterproof coating.
Xtratherm offers a cost effective solution for builders and specifiers for the closing of cavities around window and door openings, preventing cold bridging, damp penetration, air infiltration and condensation.

XT/PR-UF
Thin-R Pitched Roof XT/PR-UF on sloped roofs (ventilated, hybrid or warm) provides the most efficient U-values with minimal intrusion into valuable living space. The roof construction is a critical element in the building fabric and is an area at high risk of heat loss. Using XT/PR-UF will reduce heat loss while also delivering excellent thermal bridging details.
Warm Roof construction is a particularly effective way of insulating complex roofs. Insulating above – or above and between – the roof timbers ensures that the structure is kept at or near the internal environmental conditions, reducing thermal stress and condensation risk.
