Cavity Closers

Heat loss and condensation through un-insulated door and window reveals can ruin an otherwise warm and comfortable home. 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 Manthorpe range of Cavity Closers offers an economical solution to closing the cavity at window and door reveals without the need to return the block work while also solving cold bridging problems. Our Rigid Frame Formers can also be used as a dummy window former, these made to measure products can do away with the hassle and wastage of constructing temporary wooden surrounds.
