Thermo-loc FR60 150+

60-minute fire-rated cavity closer for cavity widths above 150mm up to 300mm..

Fire rated barriers for eliminating damp and cold bridging around doors, windows and sills.

Use cases:

• 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 minimum15 minutes insulation
• Suitable for cavities over 150mm up to 300mm
• Suitable for timber and masonry walls

No check reveal option available for Thermo-loc FR60 150+.

Installation advice

• 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.

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
• Supplied with 4 metal fixing flanges that must be slotted into place.

Technical considerations

• 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 potential of zero and global
warming potential of zero.
