Thin-R Pitched Roof XT/PR insulation board used 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.

The can be used as a general purpose insulation board in a variety of locations during construction. Please check the suitability first.
