Description

Mannok Isoshield Full Fill Cavity is a high-performance PIR cavity wall insulation board designed to utilise the full cavity width without compromising wall weathertightness. The board features profiled tongue-and-groove edges that aid installation, ensure continuity of insulation across joints, and eliminate moisture ingress risk. With thermal conductivity of 0.022 W/mk and low emissivity composite foil facings, Isoshield maximises thermal resistance of the residual cavity. This delivers U-values that meet and exceed current building regulations whilst maintaining overall wall thickness.

The board is straightforward to cut and fit on site. By fully utilising cavity space, this insulation significantly improves wall thermal performance. We stock equivalent full fill cavity insulation from Mannok, Ecotherm, IKO, Recticel, and Unilin, subject to availability. We will dispatch whichever brand is in stock.
