Thermo-loc Platinum+
Cavity closers 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
- Suitable for cavities up to 150mm

Features & Benefits
- Effective DPC and thermal barrier between frame, inner and outer wall leaf
- Thermal conductivity of 0.031W/m2k
- Exceeds the minimum thermal resistance path of 0.45m2 K/W stipulated in accredited construction details
- Rigid profile extrusion allows second fix
- Durable and resistant to decay
- Simple on-site trimming to cope with ‘rogue’ cavity widths • Global warming potential of less than 5
- Ozone depletion potential of zero
- Available fully rebated - Check reveal (single flange)
Applications
Technical Information
- BRE Document ‘Thermal insulation: avoiding risks’ 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 have an ozone depletion potential of zero and global warming potential of less than 5 and complies with BS EN 13163.

- Multi 100mm, Multi 100mm CR and fixed cavities
- 2.4m lengths
Installation advice
- The accredited construction detail published by DCLG require a minimum overlap of 30mm between the window frame and cavity closer
- Cutintorequiredlengthsallowingjambsectiontooverlapthesillsectionbycutting away parts of the fixing flange and to butt the underside of the lintel.
- 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, or alternatively the insulation can be trimmed to fit using a sharp knife
- Fixing nails to the flanges are recommended to ensure a secure fit
- Cavity insulation should butt tightly to the cavity closer
How to order
- Establish the cavity width and select the correct cavity closer width to ensure the cavity can be closed
- In jamb and sill applications, estimate the total length of cavity closer required and order the correct number of 2.4 metre lengths ensuring no joint pieces
