Cavity Closers

If your doors and windows aren’t properly insulated, you’re going to lose a lot of heat, allowing draughts to get in.
The Beesley & Fildes range of cavity closers offers an economical solution for closing cavities at window and door reveals while also addressing cold bridging.
Cavity closers not only provide a thermal break at the reveal of both door and window openings, but they also act as an effective vertical damp proof course (DPC), ensuring compliance with building regulations.
Once installed, they help prevent condensation and provide a neater, more airtight finish than simply leaving the cavity exposed. Thermal efficiency can be achieved assuming that all other relevant work has been done in accordance with best practice.
We also stock cavity stop socks, which act as fire cavity barriers. These often contain mineral wool and are squeezed into the cavity around eaves, compartment lines, etc., to prevent the spread of smoke and flames.
Cavity closers also save time in construction by closing the cavity without requiring the return of the blockwork. Our Rigid Frame Former can be set into a wall as a ready-made window mount, still offering all the benefits of a cavity closer.
With this bespoke, made-to-measure product, builders can do away with the hassle and waste of constructing temporary wooden surrounds.
