  • Rigid profile extruded in UPVC. Platinum expanded Polystyrene insulation 0.031W/mk. Multi 100mm, Multi 100mm CR and fixed cavities.
  • 2.4m lengths.
  • The accredited construction detail published by DCLG requires a minimum overlap of 30mm between the window frame and cavity closer.
  • Cut the cavity closer into the required lengths 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, 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.
  • 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.
