Find out moreLightweight and easy to install without special tools, this G242-100 Cavity Closer from Manthorpe is compatible with timber doors and windows. It includes a single flange feature for standard in-line cavity wall details and can be utilised in sill details by trimming the length to match the window's width and placed in the cavity at the sill. A DPC is still advised in horizontal applications.
The cavity closer is for use in individual lengths but can be pre-formed into frames or fixed straight to window and door frames. When tested with timber window/door frames and plasterboard, it works as a part of a detail to fulfil the needs of a cavity barrier set out in Part B of the building regulations.
Lengths are easy to cut with a saw and there is no risk of losing thermal efficiency. PVC flanges provide a confident method of fixing some specific products.
G245 and G246 Plastic Fixing Clips ensure the closer is mortared tightly to the brickwork. Shorter lengths can also be attached to reduce wastage.
