How to Insulate Cavity Walls with Eurowall®+

Installing 140mm Eurowall full fill insulation within a 150mm cavity delivers a U-value of 0.18 W/m²K, meeting Part L1A England 2013 and Part L1A Wales 2014 requirements. This approach preserves existing architectural designs whilst avoiding increased building footprints or reduced internal dimensions.

Recticel Eurowall 140mm comes in alternative thicknesses: 75mm for 85mm cavities and 90mm for 100mm cavities. The streamlined profile provides sufficient clearance for conventional bricklaying methods, enabling bricklayers to efficiently position outer leaf bricks without compromise.
