SR Pitched Roofs Xtratherm Safe-R is a superior performance rigid insulation with enhanced fire performance, consisting of a Class ‘O’ phenolic foam core with negligible smoke obscuration. Safe-R is faced with low emissivity aluminium facings both sides, and has a thermal conductivity as low as 0.020W/mK. Using Xtratherm Safe-R SR/PR on sloped roof areas can provide the most efficient U-values with minimal intrusion into valuable living space. Warm Roof construction is a particularly effective way of insulating complex roofs. Insulating above and between the roof timbers ensures that the structure...

Ventilated Roof Typical U-Values Allow for ventilation gaps normally 50mm. (May be reduced depending on breather membrane certification). (Warm Roof) Cut Xtratherm SR/PR boards to fit tightly between rafters flush with rafter bottom. An additional 2nd layer should be added to the underside of the rafter. Run second layer transverse to the first. Temporarily fix with nails. Provide vapour control layer (Aluminium tape joints). Finish with 12.5mm plasterboard fixed with drylining screws. Screw fix every 150mm, 12mm from edge of boards. All board edges should be supported. Safe-R Thickness Rafter...
