Insulated DPC for building-in as work proceeds.
ROCKCLOSE® is an insulated damp proof course, specifically developed to minimise thermal bridging at door and window reveals in masonry cavity walls. The product consists of a strip of semi-rigid non-combustible ROCKWOOL® insulation, bonded to a black polyethylene DPC (to BS 6515), and designed to be installed as work proceeds between the outer masonry leaf and internal closer block prior to the frames being fitted.
