90mm Recticel Eurowall Plus Cavity Wall Boards

90mm Recticel Eurowall Plus Full Fill delivers premium thermal performance for cavity wall applications with precision-engineered tongue and groove joints across all four edges. This interlocking design minimises thermal bridging and heat loss whilst providing excellent protection against wind-driven rain and moisture ingress. The 90mm thickness works perfectly within 100mm cavities, leaving a 10mm space for conventional mortar application during installation.

How to Insulate Cavity Walls with Eurowall®+

Installing 90mm Eurowall full fill insulation into a 100mm 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 spaces.

Recticel Eurowall 90mm is complemented by 75mm for 85mm cavities, 115mm for 125mm cavities, and 140mm for 150mm cavities. The compact profile accommodates traditional bricklaying methods, enabling bricklayers to efficiently position outer leaf bricks without obstruction.
