Insulated Cavity Closers

The problems of cold bridging are recognised in the Part L Building Regulation 2010 and Scottish Building Regulations 2004. Dacatie Insulated Cavity Closers are used to overcome thermal loss that occurs around unprotected cavities and reveals. Thermal loss can result in problems of condensation, staining and mould growth at the reveals of these openings. Prolonged exposure to such factors will lead to a deterioration of the internal Plaster and paint work. The use of Dacatie Cavity Closers will help to prevent the occurrence of such factors.

The use of a Dacatie Cavity Closer or frame former will prevent the ingress of water around a window or door. To achieve this it is important to specify a frame setback position of 30mm with a recognised sealant around the frame.

Where a fire barrier is required, a Dacatie Fire Rated Cavity Closer (Pages 9-12) should be used. The closers have fire integrity ratings from 30 minutes to an hour.

Building Regulation (Part L) compliance is important. The path of minimum thermal resistance through the closer must be at least 0.45 m2K/W, which Dacatie Closers achieve.

It is the responsibility of the contractor to ensure frames are supplied as ordered before installation, as no responsibility for any incorrect dimensions can be considered after the frame former has been built into the brickwork. Note: when ordering for Timber frame constructions, please contact our technical department.
