75mm Xtratherm Thin-R PIR Insulation
Xtratherm Thin-R XT/PR
75mm pir insulation range is a high performance foil faced Polyisocyanurate (PIR) insulation with a certified thermal conductivity as Low as 0.022 W/mK. Thin-R Pitched Roof XT/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 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.

Handling, Cutting and Storage
75mm pir insulation should be stored off the ground, on a clean flat surface and must be stored under cover. The polythene wrapping is not considered adequate protection for outside
exposure. Care should be taken to protect the insulation in storage and during the build process. The insulation boards can be readily cut using a sharp knife or
fine toothed saw. Ensure tight fitting of the insulation boards to achieve continuity of insulation as asked for within the ACDs. Appropriate PPE should be worn when handling insulation.
Please refer to Health & Safety data sheets on our website. The boards are wrapped in polythene packs and each pack is labelled with details of grade/type, size and number of pieces per pack.
Xtratherm products are stable, rot proof and will remain effective for the life span of the building, dependent on specification and installation. Care should be taken to avoid contact with acids,
petrol, alkalis and mineral oil, when contact is made, clean materials in a safe manner before installation.
