Xtratherm Pitched Roof
Xtratherm Pitched Roof Insulation XT/PR Vented Slope
Xtratherm Polyisocyanurate (Polyiso) is a thermoset closed cell rigid foam insulation. During a continuous manufacturing process, liquid raw materials expanded by blowing agents are applied between a variety of engineered facings. The facings provide strength, rigidity and enhanced thermal performance.
Xtratherm Thin-R is CFC/HCFC free (Zero Ozone Depletion Potential)
Placing the Xtratherm Thin-R between and/or below the rafter is known as a ‘Cold roof’. Because of the risk of interstitial condensation, building regulations require a continuous 50mm ventilation space to be maintained between the insulation and the roof tile underlay. This allows any moisture to be vented out of the construction. With the requirement for more rigorous thermal insulation standards in addition to this 50mm ventilation space, only rigid high performance insulants provide the solution with minimal intrusion into the living area below.
