90mm Eurowall Insulation 1200x460 Tongue&Groove 4 sides

As a leading builder’s merchant, we supply 90mm cavity insulation designed for reliable thermal performance and easy insulation. These Eurowall+ boards, which are 1200 x 460 x 90 mm and have tongue-and-groove edges on all four sides, ensure a snug fit and reduce the risk of gaps. Developed with installers in mind, their compact board size allows conventional bricklaying methods to be used as the outer leaf brick can be rolled into place, saving both time and effort.

The precisely cut edges on these boards reduce thermal bridging, shield against wind-driven rain, and increase overall windtightness. They are a wise choice for energy efficiency due to their low-emissivity foil facing, which further enhances thermal resistance within the cavity.

Whether you’re working on a new build or upgrading existing walls, these 90mm cavity wall insulation boards provide excellent protection, strength, and durability, all while meeting modern insulation standards.
