Insulated extrusions for closing wall cavities at openings.
For closing cavities around wall openings in masonry cavity, timber frame and steel frame system (SFS) wall constructions.
A cavity closer comprising a PVC-U extrusion with a premium performance rigid thermoset fibre-free phenolic insulation core.
Available in thirteen profile widths ranging from 50–150 mm. Jointing clips extend the range further by enabling sections to be coupled back-to-back, in order to suit cavity widths of up to 300 mm.
The casing incorporates tee projections along one plane length for the prevention of water tracking within the cavity, and fins along the widest plane length, which forms an effective key for the direct application of plaster or screed.
The cavity closer is manufactured under a management system certified to ISO 9001: 2015 (Quality Management Systems. Requirements), ISO 14001: 2015 (Environmental Management Systems. Requirements), BS OHSAS 18001: 2007 (Occupational Health & Safety Management Systems. Requirements) and ISO 50001: 2011 (Energy Management Systems. Requirements with guidance for use).
