RockClose® EN

RockClose EN is an insulated cavity closer designed to minimise thermal bridging around windows and doors and also acts to inhibit the passage of smoke and fire within masonry, timber and steel frame constructions.

The product consists of a strip of semi-rigid non-combustible ROCKWOOL insulation, bonded to a flexible waterproofing layer for use in external wall applications which require a DPC separation layer.
