Kingspan Kooltherm® Cavity Closer is a PVC–U extrusion with a rigid thermoset insulation core, manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP). It is manufactured in thirteen sizes from 50–150 mm. Jointing clips extend the range further by allowing the Kingspan Kooltherm® Cavity Closer sections to be joined to suit cavity widths of up to 300 mm. It is suitable for use with timber, metal or PVC window frames and can also be supplied to order in curved sections.
Kingspan Kooltherm® Cavity Closer provides a simple and efficient method of closing cavities around openings in cavity walls. Its rigid thermoset insulation core prevents thermal bridging, and its PVC–U J–section forms a positive damp proof barrier and key for the direct application of plaster. It effectively prevents condensation and mould growth, frequently associated with traditional methods of closing cavities.
