100% recycled PVC-U, easy-to-install component designed to save time, money – and the environment.

 

Designed with sustainability in mind, our cavity closer is manufactured entirely from recycled material and incorporates an insulation core to enhance thermal efficiency. This pre-installed polystyrene core also saves time on site, since no additional insulation is required.

 

The unique clip-together system requires no specialist tools or adhesives for assembly, and creates an effective damp-proof barrier that offers consistent performance, every time. The cavity closer provides a rigid template for brick and block work and facilitates straightforward, rapid window installation.

Our PVC-U cavity closers are the simplest, most effective components for sealing cavities around openings in masonry walls. They are an essential component for any new-build project – large or small – helping to optimise time spent on site and boost the productivity of installation teams.

 

 

The cavity closer allows pre-glazed windows to be fitted very quickly, using our quick-fit spring-clip system – optimising time on site and improving productivity for installers.
