Unilin Insulation Safe-R Pitched Roof Board (2400 x 1200 x 75 mm)
Safe-R is a superior performance phenolic insulation. It is faced with low emissivity foil facings on both sides and has a Lambda value as Low as 0.020 W/mK.
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.
