Thermo-loc Platinum Plus Multi Cavity Closer is a durable and resistant barrier used for eliminating cold bridging and damp from around walls, windows and sills. It provides a suitable Damp Proof Course and thermal barrier between frame, inner and outer wall leaf. You can quickly and easily trim the multi-width profiles on-site to suit a variety of cavity width requirements. Cavity closers are rigid and lightweight UPVC profiles fitted with insulation material. They are used to close openings in cavity walls, such as external walls and windows and can also be used to pre-form openings when the door and/or window frames are to be installed later. However, cavity closer's are non-load bearing and should not be used as a replacement for traditional methods of fixing window and door frames to the masonry.

Features & Benefits: Timloc 2.4m Thermo-loc Platinum Plus Multi Cavity Closer - 50mm to 100mm

  • Can be used in second fix applications
  • Rigid profile extrusion
  • Exceeds the minimum thermal resistance path of 0.45m2k /w stipulated in accredited construction detail
  • Quick and easy on site-trimming to cope with "rogue" cavity widths
  • Durable and resistant to decay
  • Profile can be easily cut using the pre-cut grooves and installed on site
  • Ozone Depletion: Zero

Insulation should be extended from the lower closer profile to allow this to slot into the upper profile to maintain a rigid section.


  • Simply cut your Cavity Closer to the required length, allowing the jamb section to overlap the sill section by cutting away parts of the fixing flange and to butt the underside of the lintel. For second fix applications, push the Cavity Closer into the open side of the cavity after building work is complete. The compressible nature of the exposed insulation is used to create a friction fit into the cavity; alternatively, you can trim the insulation to fit using a sharp knife. The accredited construction detail published by DCLG require a minimum overlap of 30mm between the window frame and cavity closer
