    Mannok Full Fill Iso Cavity 1200 x 450 x 90mm

    Full fill cavity wall insulation allows more of the cavity between the inner and outer leaf to be filled with insulation, providing a much better insulated structure without increasing the wall width. Partial fill cavity wall insulation typically requires a 50mm residual cavity to be maintained, however with advanced manufacturing techniques and testing, Mannok IsoCavity insulation is fully tested and certified with a residual cavity of 0mm – 10mm.

    Mannok IsoCavity PIR insulation boards provide a superior cavity wall insulation solution which combines ease of construction with all the benefits of Full Fill PIR. The boards have a thermal conductivity of 0.022W/mK, precision cut tongue and groove edge and multi-layer foil facings, combining thermal performance with ease of construction.
