Superior Performance Phenolic Insulation

SR/PR

Applications: Roof / Pitched

SR/PR

SR/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 SR/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.
