For many years cavity closers have provided a reliable solution to the problems of thermal bridging at window and door openings. However, a cavity closer is only a component part of a cavity barrier.
Building products manufacturer Manthorpe has recognised the industry want for a true one-product cavity barrier which provides the necessary thermal and DPC properties without depending on specific build and material details to fulfil the requirements of a cavity barrier.
REDSHIELD cavity barriers adapt to cavity opening variations which means optimal thermal and DPC performance, and the secure closing of the cavity in the event of a fire. Tested by Warringtonfire to BSEN1366-4:2006+A1:2010, independently of other barrier detail, REDSHIELD cavity barriers exceed the required 30 minutes’ fire integrity and 15 minutes’ insulation.
REDSHIELD cavity barriers are currently available in four size configurations, plus rebated versions, with a 130-160mm variant available from summer 2020.
