Cavity Closers

Our Cavity Closer is a former and damp-proof course; available in standard and check reveal options for building into reveals in new build constructions.

Suitable for all new build applications, our former meets NHBC standards and offers thermal and energy efficiency performance required for Part L of Building Regulations. Accepts 63mm and 70mm PVC-U systems. Guarantees size of aperture so windows can be fitted later in the build reducing risk of damage.
