PIR L polyurethane insulation

Description

UTHERMroof PIR L polyurethane insulation is a rigid insulation board intended for EPDM roofing systems and flat roofs. Compatible with RT 2012 solutions, it is used on concrete, masonry, timber or wood-based board substrates, in one or two layers of insulation. Thanks to its PIR polyurethane foam and its watertight multi-layer Kraft-PE-Alu facing, it offers excellent mechanical and thermal performance for non-accessible, technical, green or pedestrian-accessible roofs. Advantages Compatible with RT 2012 solutions Used in one or two layers of insulation Compatible with concrete, timber and masonry substrates Suits green roofs and technical terraces Excellent compressive strength Watertight multi-layer facing Foam free of HFC, HCFC and CFC Suited to EPDM waterproofing systems Good dimensional stability Boards with square edges on all 4 sides Applications Non-accessible flat roofs Technical terraces Pedestrian-accessible terraces Green roofs Roof gardens Substrates for EPDM waterproofing Flat roof insulation Technical characteristics UTHERMroof PIR L insulation Rigid PIR polyurethane foam Blowing gas free of HFC, HCFC and CFC Density: 32 kg/m³ Kraft-PE-Alu facing, 150 g/m², on both faces Compressibility class: C Compressive stress at 10 %: ≥ 150 kPa Critical compressive resistance Res: 120 kPa Conventional deformation ds: 0.91 % Residual dimensional change: ≤ 0.3 % Thermal bowing: ≤ 1.5 mm Boards with square edges Dimensions: 600 x 600 mm Laid on a vapour barrier with a glass tissue separating layer
