Recticel Eurothane® GP - 2400mm x 1200mm - All Thicknesses

• Suitable for multiple applications
• Good thermal performance: λ = 0.022 W/mK
• Quick and easy installation

Walls/floors/roofs: Recticel Eurothane PIR (polyisocyanurate) insulation offers excellent thermal performance, making it a superior choice for various construction applications. Its high R-value per inch ensures effective insulation, helping to reduce energy consumption and lower heating and cooling costs. Additionally, its lightweight and easy-to-install nature make it a convenient option for builders and contractors, contributing to faster construction times and overall project efficiency.

• What air gap is required between insulation and breather membrane? - This should be confirmed in the membrane manufacturer's BBA certificate, though 25mm to 50mm is typical.
• Is a vapour control layer (VCL) required in a floor insulation application? - In addition to the damp proof membrane (normally a 1200-gauge polythene sheet below the insulation), a 500-gauge polythene VCL should be laid over the insulation. Where a concrete slab or a screed is to be poured on top, the VCL will also protect the foil face of the board from alkalis within the concrete, and stop poured concrete opening board joints and causing a thermal break.
• Can PIR insulation boards be used directly below flooring tiles? - No, PIR insulation boards should not be used directly below flooring tiles, a suitable substrate such as screed should be used to distribute the load and prevent movement and cracking of the tiles.
