Cavity Closers not only provide a thermal break at the reveal of both door and window openings, they also act as an effective vertical damp proof course (DPC), ensuring compliance with building regulations.
The G240 Cavity Closer has a double flange feature for use in standard in-line cavity wall details. It is also used in sill details by simply cutting a length to suit the width of the window and placed in the cavity at the sill. A DPC is still recommended in horizontal applications.
The lightweight closers are available in sizes to suit all cavity widths and are simply installed, requiring no special tools. Lengths can be simply cut with a saw, with no loss of thermal efficiency. PVC flanges provide a secure method of fixing using dedicated fixing clips.
The closer can be used in individual lengths, or some may be preformed into frames or fixed directly on to window and door frames
