G241
The G241 is an economical, single extrusion fitted version of the G240. It is also used in sill details by simply cutting a length to suit the width of the window and placing it in the cavity at the sill. G241 not only provides a thermal break to the cavity but also acts as an effective vertical DPC barrier, 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, and with some specific products, PVC flanges provide a secure method of fixing.
The closer can be used in individual lengths, or some may be preformed into frames or fixed directly on to window and door frames.
The G241M Multi Width Cavity Closer has groove guides which allow it to be cut to a variety of widths.
The cavity closer is non-load bearing and should not be used as replacement for traditional methods of fixing window and door frames to the masonry.
