TH31 40 mm grey EPS insulation board – ISOL France

Grey insulation designed to last, façade after façade

Among the external thermal insulation solutions offered by ISOL France, the 40 mm-thick ISOLITEX GRIS 31 panel is designed for professionals seeking a reliable grey expanded polystyrene (EPS) panel for their façade projects, whether in new-build or energy-efficient refurbishment. This panel completes a range designed to meet all external insulation needs, from simple thermal reinforcement to the most demanding energy performance requirements. This panel, in the standard size of 1200 x 600 mm, has a thermal conductivity of 0.031 W/(m·K) – corresponding to TH31 class – and a thermal resistance of R = 1.60 m².K/W at this thickness of 40 mm. Its reaction to fire is classified as Euroclass E, according to the LNE’s European classification report, and the product holds ACERMI certification no. 15/171/1016. In terms of installation, it is laid by bonding and/or fixing with dowels to masonry, concrete or timber frames, in accordance with the specifications of the chosen ETICS system. Its light weight and ease of cutting make it a popular choice amongst installation teams, without compromising on the precision required on site, whether for standard surfaces or façades with complex features (corners, window surrounds, window sills). This panel also enables compliance with the requirements of the HQE and BBC certification schemes, a key benefit for project owners concerned with the building’s overall energy performance. It is aimed at façade specialists, external thermal insulation contractors and building tradespeople seeking a certified and sustainable insulation material. Once installed, it is covered with a fibreglass mesh embedded in an undercoat, followed by an adhesive primer before the chosen façade finish is applied, thus completing a coherent external thermal insulation system from the substrate right through to the finish. Like the entire ISOLITEX GRIS 31 range, this panel is available in several thicknesses, from 20 to 300 mm, allowing the required thermal resistance to be precisely tailored to the regulations applicable to the project and the energy performance targets set by the client.

Our ITE expert’s opinion

In this project, the choice of a 40 mm TH31 graphite PSE is justified whenever the thermal requirements are stringent: its low thermal conductivity often makes it possible to achieve the targeted performance without making the system unnecessarily thick. At this thin gauge, the TH31 really comes into its own in specific areas where every millimetre of resistance counts.
