Thermo-loc Multi Cavity Closers

Rigid profile extruded in white PVC-U used to close cavities of 50-100 mm at external doors, window jambs and sills.

Available with standard expanded polystyrene (EPS) insulation (white), or extruded polystyrene (XPS) insulation (pink), which is pre-grooved to offer cut lines for regular cavity sizes.

Features:

• Provides an effective DPC and thermal barrier between frame, inner and outer wall leaf.

• Exceeds the minimum thermal resistance path of 0.45 m²K/W stipulated in Robust Details Limited Thermal Bridging and Air Leakage.

• Rigid profile extrusion allows both first and second fix.

• Suitable for all frame and sill positions.

• Durable and resistant to decay.

• Insulation option to suit requirements both thermally and for fire rating.

• Simple on-site trimming to cope with non-standard cavity widths.

• Low ECO points rating. Ozone depletion level of zero. Global Warming Depletion level of 4.4.
