60-minute fire-rated cavity closer.
Fire rated barriers for eliminating damp and cold bridging around doors, windows and sills.
- To close the cavity at external doors, window jambs and sills
- To provide thermal insulation and prevent ‘cold bridging’
- To provide a DPC at external doors, window jambs or sills
- 60 minutes fire rating and minimum 15 minutes insulation
- Suitable for cavities up to 150mm
- Suitable for timber and masonry walls

Material and colour choice
- Rigid profile extruded in white UPVC
- Supplied in 2.4 metre lengths
- Standard cavity options available 50mm - 150mm
- Rockfibre mineral wool (FR) insulation 0.036W/mk
- Can be used in both first and second fix applications
- Cut the cavity closer into required lengths allowing the jamb section to overlap the sill section and to butt the underside of the lintel
- In first fix application the cavity barrier should be nailed to the jamb/sill of the door or window frame and the whole assembly built in as work proceeds. Alternatively the barrier can be built in sections using fixing ties as work proceeds.
- For second fix applications, the cavity barrier is pushed into the open cavity after building work is complete. The compressible nature of the exposed insulation material is used to create a friction fit in the cavity, secure nail fixing is required.
- Joining ‘off cut’ sections should not be carried out for the FR range
How to order
- Establish the cavity width and select the correct cavity barrier width, or the next size up to ensure the cavity can be closed
- In jamb and sill applications, first estimate the total length of cavity barrier required, then order the correct number of individual 2.4 metre lengths so limiting joint pieces
- Fixing ties are available for secure fixing if required (particular attention around door openings). Allow for ties fitted at 450mm centres
- BRE Document ‘Thermal insulation: avoiding risks’ and Robust Details stipulate: “When a window or door frame is set back behind the inner face of a dense outer masonry leaf, it should overlap an insulated closer by a minimum of 30mm for BRE exposure zones Sheltered to Severe; but fully rebated (check reveals for zones Very Severe’’ (see Fig.2)
- With reference to insulation, the products in this range do not use, contain or produce Urea Formaldehyde, CFC’s or indeed any of the so called soft CFC’s, ie. HCFC’s & HFA’s. They conform to the Montreal Protocol and have an ozone depletion potential of zero and global warming potential of zero.
