Thermabate Cavity Closer
Product Description
Thermabate insulated cavity closers are supplied in six basic sizes to suit cavities 50-100mm wide.They are colour coded for ease of identification.
Wider cavities can be closed using the jointed clip to link two sections together.
The Thermabate insulated cavity closer 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.
Thermabate insulated cavity closer obviates the need for cut bricks or blocks to close cavities and avoids problems encountered when supporting traditional dpcs and insulation boards during construction
Thermabate is a PVC-U extrusion with a CFC/HCFC-free insulating core, available in six sizes, colour coded for instant identification. Jointing clips extend the range further by allowing the Thermabate sections to be joined. Thermabate ensures a more positive detail around openings and offers a time saving profile when built in. It is suitable for use with timber, metal or plastic window frames and can also be supplied to order in curved sections
