Insulated cavity closer for door and window openings.
An insulated cavity closer designed to be used as a dpc at door and window openings in cavity wall construction. It consists of a tissue-faced rock fibre slab, laminated to black polyethylene DPC material, which forms a 40 mm flange on each side of the insulation and a 100 mm flange at the bottom edge.
The cavity closer should be fitted as the wall constructed, before the installation of door and window frames. It should be fitted with the dpc face against the inner face of the outer leaf of masonry. The outer flange should be folded back against the reveal when the frame is fitted.
