PSE Grey ISOL France TH31 160 mm ACERMI R=5.15

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

The ISOL France TH31 grey EPS panel, 160 mm thick, is a rigid expanded polystyrene insulation board, designed for external wall insulation (EWI). Its TH31 graphite-modified polystyrene formulation offers the best thermal performance in the ISOL France range for panels of the same thickness, a key advantage for optimising the total thickness of the ETICS system. This is a feature sought after by professionals involved in energy-efficient refurbishment or new-build projects. Measuring 1200 x 600 mm, this ISOLITEX GRIS 31 panel has a thermal conductivity of 0.031 W/(m·K) and a thermal resistance of R = 5.15 m²·K/W at a thickness of 160 mm. 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-fixing system, depending on the specifications of the substrate and the chosen insulation system. It is compatible with ETICS systems covered by a technical approval. It can be supplied in a tongue-and-groove version to facilitate installation and minimise thermal bridges between panels. 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 certification schemes. It is aimed at 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, a bonding primer and then a facade finish of your choice (thin-set render, acrylic-siloxane or mineral coating). This combination ensures the wall’s thermal performance, protection against the elements and a long-lasting aesthetic finish, whilst simplifying site management thanks to a standardised 1200 x 600 mm format that can be easily laid out across the entire façade.

Our ITE expert’s opinion

For this project, the choice of a 160 mm TH31 graphite PSE is justified whenever the thermal target is tight: its low thermal conductivity often makes it possible to achieve the desired performance without making the system unnecessarily thick.
