For closing cavities around wall openings in masonry cavity wall constructions.

Kingspan Kooltherm Cavity Closer is a cavity closer J-section comprising a uPVC extrusion with a premium performance fibre-free rigid thermoset phenolic insulation core.

Sections are manufactured in thirteen profile widths ranging from 50-150 mm and are available as standard in 2.4 m lengths. 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 form an effective key for the direct application of plaster or screed.
