Plastics, insulated cavity closer for openings in masonry cavity walls.
A cavity closer comprised of a rigid PVC-U extrusion, insulated with expanded polystyrene for use in external masonry cavity walls at window and door jambs and sills that also provides a dpc and helps prevent 'cold bridging'.
Slight compressibility of the insulation on the closer allows cavity imperfections at abutting wall faces to be overcome
Simple on-site adjustment to cope with rogue cavity widths by trimming down insulation
Rigid profile extrusion provides firm support for insulation during and after installation
Ribs deter water capillary action and offer anchorage for mastic sealants and foam fillers
Durable and resistant to decay
The product is not recommended for use with full fill cavities
Satisfies NHBC standards, complies with Building Regulations Approved document C (2004 edition), L1 and L2 (2006 editions)
