• Good thermal performance: λ = 0.022 W/mK
• Limited moisture absorbtion
• Durability

Walls/floor/roof: Recticel Eurothane GP insulation provides versatile performance for a wide range of applications. Its closed-cell structure offers excellent thermal efficiency, contributing to energy savings and maintaining comfortable indoor temperatures. With its durability and moisture resistance, Eurothane GP ensures long-term performance, making it a reliable choice for both residential and commercial projects.

• What is Recticel Eurowall Cavity Insulation? - Recticel Eurowall Cavity Insulation is a rigid polyisocyanurate (PIR) foam board designed for use in cavity wall constructions. It provides excellent thermal insulation and features low emissivity foil facings on both sides to enhance its thermal performance
• How does Recticel Eurowall Cavity Insulation contribute to fire safety?
  Recticel Eurowall Cavity Insulation is classified as Euroclass F according to EN 13501-1, which means it should be used in conjunction with other materials and construction methods that meet the overall fire safety requirements of the building​
• Is Recticel Eurowall Cavity Insulation suitable for both new builds and retrofits? -Yes, Recticel Eurowall Cavity Insulation is suitable for both new constructions and retrofits. Its design allows for easy integration into existing cavity walls, making it a versatile option for various building types​
• 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.
