• Meets all relevant British Standards

• Rigid profile extruded in white UPVC. Supplied in 2.4 metre lengths.
• Standard cavity options available 50mm – 300mm. 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 closer 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 closer 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 no joint pieces.
• Fixing ties are available for secure fixing if required (particular attention around door openings). Allow for ties fitted at 450mm centres.
