115mm Recticel Eurowall Plus Cavity Board

115mm Recticel Eurowall Plus Full Fill is a premium-grade insulation board engineered with interlocking tongue and groove joints across all four edges. This sophisticated joint system creates a secure connection between boards, substantially reducing thermal bridging and heat loss. The advanced joint design also provides superior protection against wind-driven rain penetration and enhanced windtightness. With a 10mm cavity allowance, 115mm Eurowall Plus enables conventional bricklaying methods without compromise.

How to Insulate Cavity Walls with Eurowall®+

Installing 115mm Eurowall full fill insulation within a 125mm cavity delivers a U-value of 0.18 W/m²K, meeting Part L1A England 2013 and Part L1A Wales 2014 requirements. This approach preserves architectural designs whilst avoiding increased building footprints or reduced internal spaces.

Recticel Eurowall 115mm is also supplied in 75mm for 85mm cavities, 90mm for 100mm cavity and 140mm for 150mm cavities. Its streamlined profile provides adequate space for traditional bricklaying practices. This enables bricklayers to confidently 'roll' the outer leaf bricks into position, maintaining workflow efficiency.
