High Performance rigid extruded polystryrene


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.

CavityTherm 360

An engineered system providing added resilience against increases in wind-driven rain resulting from climate change. CavityTherm 360 is a bio-enhanced high performance composite board of enhanced PIR with a Lambda value as low as 0.020 W/mK for full fill cavity wall applications.

CavityTherm 360 offers all of the unique benefits of our full fill built-in wall insulation system along with pioneering environmentally sensitive features that meet both the RIBA 2030 Climate Challenge and LETI targets.

When built into a traditional 110-150mm cavity using standard foundation widths, building skills and local materials CavityTherm 360 achieves U-Values down to 0.12 W/m2K. An environmentally conscious solution to low energy design, that results in traditional homes that meet the RIBA 2030 Climate Challenge targets.
