ISOL France – TH31 Grey PSE, thickness 60 mm, R=1.90

ISOL France TH31 60 mm – ACERMI-certified grey PSE

The right panel, with the right thickness, for a well-insulated façade

The choice of insulation thickness directly determines the thermal performance of a façade: at 60 mm, ISOL France’s ISOLITEX GRIS 31 panel achieves a thermal resistance of R = 1.90 m².K/W, thanks to a certified thermal conductivity of 0.031 W/(m·K) (class TH31). This level of performance enables the precise design of an external thermal insulation project, whether to comply with current thermal regulations or to achieve an energy performance certificate. This grey expanded polystyrene panel, measuring 1200 x 600 mm, is designed for the external thermal insulation of walls on masonry, concrete or timber-frame structures. It is ACERMI-certified (No. 15/171/1016) and classified as Euroclass E for reaction to fire according to the LNE report – two useful guarantees for validating a project with a design consultancy or project manager, in both new-build and refurbishment projects. Installation – whether bonded and/or fixed with dowels, depending on the substrate and the chosen ETICS system – remains quick and straightforward thanks to the material’s light weight and the ease with which it can be cut on site. It enables compliance with the objectives of the HQE and BBC labels, in both new-build and energy-efficient refurbishment projects, whilst minimising the physical strain of handling for installation teams. This panel is designed for façade contractors, external thermal insulation contractors and building professionals seeking a certified, cost-effective and tried-and-tested solution for their external insulation projects. Once the panel has been installed, a fibreglass mesh is embedded in an undercoat render; an adhesive primer and a façade finish then complete the external thermal insulation system, resulting in a wall that is insulated, protected and aesthetically pleasing over the long term. ISOL France’s ISOLITEX GRIS 31 range covers thicknesses from 20 to 300 mm, thereby offering a wide range of thermal resistance values to meet the requirements of every façade configuration, whether it involves a simple upgrade or an ambitious energy performance target.
