ROCKCLOSE® Insulated DPC
ROCKWOOL ROCKCLOSE® is an insulated cavity wall closer that has been designed to prevent thermal bridging by addressing heat loss around door and window reveals.
Consisting of a strip of semi-rigid, non-combustible ROCKWOOL® insulation, bonded to a black polyethylene DPC (to BS 6515), ROCKWOOL ROCKCLOSE® is self-supporting and easy to use.
As a cavity closer, it is used as work proceeds between the outer masonry leaf and internal closer block before the frames are fitted.
