Find out moreThis box of six Manthorpe G240-150 Cavity Closers features a double flange, suitable for use in standard in-line cavity wall details. The cavity closers can also be used in sill details, and you can simply cut the length to fit the width of your window and position them into the cavity at the sill. In horizontal applications, a DPC is still recommended.
Straightforward to install without the need for special tools, these lightweight closers can be easily cut with a saw without any loss of thermal efficiency. With some specific products, PVC flanges offer a secure method of fixing.
These Manthorpe cavity closers can be used around timber windows and doors. When tested as a collective, including plasterboard and timber door/window frames, these cavity closers can be used as a component to comply with the requirements of a cavity barrier as depicted in Part B of the building regulations.
Closers can be used as individual lengths, pre-formed into frames or fixed directly onto door and window frames. G245 and G246 Plastic Fixing Clips allow the closers to be mortared securely to the brickwork and enable shorter lengths of closers to be connected, which helps to reduce wastage.
