Clause 180 | CAVITY CLOSURES FOR CLOSING AROUND WINDOW & DOOR OPENINGS

• Manufacturer: Timloc Building Products, Timloc House, Ozone Park, Howden, East Yorks. DN14 7SD. T: 01405 765 567, W: www.timloc.co.uk
• Reference: eg. FR60/200 (Thermo-loc FR60+, 2.4m, 200mm cavity).
• Accessories: Fixing ties available, 6 No. per 2.4m cavity barrier.

• 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, 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

• 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
• Fit the 4 metal fixing flanges 100mm from each end and 100mm from the centre line. Ensure 2 fixing flanges per insulation slab section.
• 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 be minimised 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
• Supplied with 4 metal fixing flanges that must be slotted into place
