Thermo-loc Platinum Multi Cavity Closer
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
- Provides an effective DPC and thermal barrier between frame, inner and outer wall leaf
- Thermal conductivity of 0.031W/mk
- 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
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 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.
Quality
- Manufactured to BS EN ISO 9001 and BS EN ISO 14001
- Complies with Building Regulation Approved Documents C, L1 & L2
- Satisfies BRE document ‘Thermal insulation: avoiding risks’
- Meets all relevant British Standards
- Satisfies NHBC standards
Material and colour choice
- Rigid profile extruded in UPVC
- Platinum expanded Polystyrene insulation 0.031W/mk
- Multi 100mm & Multi 150mm cavities
- 2.4m lengths
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, first estimate the total length of cavity closer required, then order the correct number of individual 2.4 metre lengths so no joint pieces
Installation advice
- The accredited construction detail published by DCLG require a minimum overlap of 30mm between the window frame and cavity closer
- Cut into required lengths allowing the jamb section to overlap the sill section by cutting away parts of the fixing flange and 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, alternatively the insulation can be trimmed to fit using a sharp knife
- Fixing nails to the flanges are recommended to ensure a secure fit
