Thermabate Insulated Cavity Closers

Product Description

Thermabate provides a simple and efficient method of closing cavities around openings in masonry walls. The insulating foam core prevents thermal bridging, while the PVC-U box section forms a positive damp proof barrier and key for the direct application of plaster. It effectively prevents condensation, pattern staining and mould growth frequently associated with traditional methods of closing cavities. Thermabates closes the cavities and avoids problems encountered when supporting traditional dpc’s and insulation boards during construction.
