Cavity Closers

Pics For Website282

Heat loss and condensation through un-insulated door and window reveals can ruin an otherwise warm and comfortable home. Richard Williams stock a range of Manthrope cavity closers. The Manthorpe range of Cavity Closers offers an economical solution to closing the cavity at window and door reveals while also solving cold bridging problems. 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 Cavity Closer also addresses the issue of condensation and promotes an air tight detail. Thermal efficiency can be achieved assuming that all other relevant work has been done in accordance with best practice. They also save time in construction by closing the cavity without the need to return the block work. Cavity closers are available in a multi 50-100mm, 125mm and 150mm, all at 2500mm long.

If you require more information on our cavity closers or wish to discuss your delivery options, please contact your local branch at Llandudno Junction or Ruthin North Wales.
