Two new thicknesses for Isover's Isonat Flex range

Isover is expanding its bio-based Isonat Flex 40 and Isonat Flex 55 ranges with two new thicknesses of 220 mm and 240 mm, allowing installers to use a single layer of insulation while achieving excellent thermal resistance. This innovation meets the requirements of both converted attics (R ≥ 6 m²·K/W) and unconverted attics (R ≥ 7 m²·K/W), while simplifying installation and optimizing thermal performance, even when the roof structure presents certain constraints. Isonat Flex 55 offers a thermal conductivity of 0.036 W/(m.K), while Isonat Flex 40 boasts 0.038 W/(m.K). Both products are Acermi certified and offer excellent acoustic performance. Isonat Flex 55 stands out thanks to its unique comfort layer, which reduces dust, facilitates cutting, and improves mechanical strength during installation. Eco-designed and manufactured in France from locally sourced PEFC-certified Douglas fir, these panels combine performance, durability, and ease of installation for professionals, while also contributing to reduced heat loss.
