20mm Unilin / Xtratherm Thin-R PIR Insulation Board

Xtratherm Insulation is now called Unilin Insulation.

20mm Xtratherm Thin-R Insulation Board (2400mm x 1200mm x 20mm) is an ultra thin PIR rigid foil faced polyisocyanurate (PIR) thermal foam multi-application insulation board with a certified thermal conductivity as Low as 0.022 W/mK and designed for roofs, walls, floors, timber and steel framed systems.

About

20mm Xtratherm PIR PIR 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-UF will reduce heat loss while also delivering excellent thermal bridging details. 20mm Insulation Board is designed to be used in a variety of construction applications, such as roofing ( Pitched Roof Insulation ), walls, and floors. It is also thin, lightweight and easy to install. The board is also fire-resistant, water-repellent, and has a low environmental impact.

Warm Roof insulation 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. The 20mm 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.
