Recticel Eurowall Cavity Wall Insulation Board is a partial fill cavity wall solution with a rigid polyurethane foam core. Belonging to the PIR range of insulation boards, it has a low thermal conductivity of just 0.022 W/mK which means maximum heat retention within the building structure.
These Recticel cavity boards have precision-cut straight edges, which means that the boards can butt up tightly against one another, minimising air gaps. They are flanked on either side by a multi-layered kraft and metal foil facing, which acts as a gas diffusion layer across air space.
Eurowall cavity boards come in 1200mm x 450mm, ideal to fit between brick ties in masonry cavity walls. They can be used in both new builds and extensions and will enhance the thermal performance of any cavity space.
