Cavity Closers

As an essential part of any cavity wall construction, cavity closers fit within a cavity where doors and windows are fitted.

Our range of Dacatie and Manthorpe cavity closers will stop moisture entering the wall and will help prevent heat loss from your build.

Suitable for cavities ranging from 50mm to 150mm wide, cavity closers are easy to trim to size with a hand saw and a steady hand (remember the old adage: measure twice, cut once).
