PSE Grey ISOL France TH31 50 mm – External wall insulation board, R=1.60

PSE Grey ISOL France TH31 50 mm ACERMI R=1.60

The grey insulation that delivers long-term savings on your energy bills

The ISOL France TH31 grey EPS panel, 50 mm thick, is a rigid expanded polystyrene insulation board, designed for external wall insulation (EWI). This is the ISOLITEX GRIS 31 product from the ISOL France range, a benchmark for professionals involved in energy-efficient refurbishment or new-build projects. Measuring 1200 x 600 mm, this panel has a thermal conductivity of 0.031 W/(m·K) and a thermal resistance of R = 1.60 m²·K/W for its 50 mm thickness. It has a Euroclass E fire reaction classification, certified by the LNE. These characteristics are ACERMI-certified under reference number 15/171/1016, guaranteeing the product’s compliance with French regulatory requirements. This panel can be installed on masonry, concrete or timber frames, using an adhesive and/or dowel-fixed system, depending on the specifications of the substrate and the chosen insulation system. It is compatible with ETICS systems covered by a technical approval. Easy to handle and cut on site, it allows for rapid installation in both new-build and renovation projects. Thanks to its certified thermal performance, this panel helps meet the requirements of the HQE and BBC labels. It is designed for façade contractors, companies specialising in external thermal insulation and building professionals seeking a reliable, cost-effective and easy-to-install insulation material for their external thermal insulation projects. In a complete external thermal insulation system, this panel is combined with a fibreglass mesh embedded in an undercoat render, followed by an adhesive primer and then a facade finish of your choice (thin-set render, acrylic-siloxane or mineral coating), resulting in a wall that is high-performing, protected and aesthetically pleasing. The ISOLITEX GRIS 31 panel is available in a range of thicknesses, from 20 to 300 mm depending on the project’s requirements, allowing the target thermal resistance to be precisely adjusted without changing the product or supplier. This consistency makes it easier for contractors working on multiple external thermal insulation projects to monitor site progress and manage their supplies.
