Mannok IsoCavity is a high performance full fill PIR cavity wall insulation which utilises more of the cavity width than traditional partial fill PIR boards, without compromising the weathertightness of the wall.

Mannok IsoCavity board, which is easy to cut and fit, is manufactured with profiled tongue-and-groove edges which aids installation, ensure continuity of insulation across the joint and eliminates any risk of moisture ingress.

With a thermal conductivity of 0.022 W/mk and with low emissivity composite foil facings increasing the thermal resistance of the residual cavity, Mannok IsoCavity maximises the thermal performance of the wall resulting in U-Values which can easily meet and exceed all current building regulations.

By fully utilising the cavity, Mannok IsoCavity will significantly increase the thermal performance of the wall without increasing the overall thickness of the wall.
