• Ozone depletion potential of zero
• Available fully rebated – Check reveal (single flange)

• Independently tested by Warrington Fire
• Satisfies NHBC Standards
• Manufactured to BS EN ISO 9001 and BS EN ISO 14001
• Complies with Building Regulation Approved Documents C, B, L1 & L2
• Complies with ‘Part L’ accredited construction details
• Complies with the Scottish Building Standards ‘Technical handbook’
• Satisfies BRE document ‘Thermal insulation: avoiding risks’
• Meets all relevant British Standards

• 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 or 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.

• 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.

With reference to insulation, the products in this range do not use, contain or produce Urea Formaldehyde, CFCs or indeed any of the so-called soft CFCs, i.e. HCFCs & HFAs. They conform to the Montreal Protocol and have an ozone depletion potential of zero and global warming potential of zero.
