Cavity Closers

A complete and simple solution to thermal bridging where the cavity is open, ie; inner blockwork and outer brickwork are constructed in a straight build with no return.

The product is installed into the cavity between the inner blockwork and outer brickwork after the construction of the walling, providing both insulation and damp proofing.

This helps to prevent problems such as condensation, leading to possible staining and mould growth, which are associated with poor thermal bridging around doors and windows.

Polypipe TDI manufacture a complete range of insulated cavity closers to suit various cavity widths, with both standard insulation and fire
retardant insulation.
