100% recycled PVC-U, easy-to-install component designed to save time, money – and the environment.
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 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.
Why choose cavity closers?
Designed with sustainability in mind, the 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.
Further time is saved by the simple clip-together closer assembly system, which guarantees fast and accurate installation. 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.
