    Cavity Closers

    Product Type:

    Market Sector:


    Manthorpe G Series Thermal Cavity Closers (60B)

    Product Description:

    Manthorpe’s Thermal Cavity Closers provide a versatile solution to cold bridging problems. They also save time in construction by closing the cavity without the need to return the blockwork.

    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. 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.

    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 onto window and door frames.
