Xtratherm Thin-R range is a high performance foil faced Polyisocyanurate (PIR) insulation with a certified thermal conductivity as Low as 0.022 W/mK. Thin-R is also available with engineered jointing to provide improved continuity and thermal bridging performance.

Thin-R Pitched Roof XT/PR 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 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.
