Thermo-loc FR30 30 Minute Fire-Rated Cavity Closer

30-minute fire-rated cavity closer for eliminating damp and cold bridging around doors, windows, and sills.

Independently tested by Warrington Fire to achieve 30 minutes fire-rating and minimum 15 minutes insulation.

Suitable for cavities up to 300mm. Available in single profile for 50mm-100mm cavities and double profile for 105mm-300mm cavities. Cavity barriers for fully rebated and check reveal are also available.

Compliant with Building Regulation Approved Documents C, B, L1 and L2 and satisfies BRE document ‘Thermal Insulation: avoiding risks’.

Fixing ties available in packs of 100.

Uses:

  • 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
  • 30 minutes fire rating and 15 minutes insulation minimum
  • Suitable for cavities up to 300mm
  • Suitable for timber and masonry walls

  • 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.
