Lightweight 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.
Please note:
Question:
My door and windows are already fitted. Can these closers be retro-fitted?
Answer:
The Manthorpe G242-100 Cavity Closer is designed for installation during the construction phase of your property, and it is typically installed before the windows and doors. Retro-fitting this product after doors and windows have already been installed could be complex and may not provide the desired thermal efficiency and continuity of insulation. Therefore, it's not typically recommended to retro-fit these cavity closers. For the best results and to ensure correct installation, it's always advisable to consult with a building professional or your installer. They can provide guidance based on the specifics of your property and existing installations.
