Kingspan Kooltherm cavity closers are made up of a high-quality, unplasticized (PVC-U) extrusion. The cavity closers are designed for closing cavities to maintain continuous insulation around wall openings in masonry cavity, timber frame and steel frame system wall constructions. This product is suitable for timber, metal, and PVC window frames.

The cavity closer box section is manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP). This product successfully prevents thermal bridging and the PVC-U box forms a damp-proof barrier and key for the direct application of plaster. The section is unaffected by air transfer and prevents condensation, pattern straining, and mould growth generally associated with traditional methods of closing cavities. This product requires simple construction avoiding the need to cut bricks, blocks, or special reveal blocks.

Kingspan Kooltherm cavity closers are extremely durable and when installed correctly will have an indefinite life, its durability depends on the supporting structure and the conditions of its use. The cavity closer product is lightweight, and packaging is compressed ensuring handling and installation is quick and easy. The slabs are 2400mm and are available in thicknesses between 50mm and 150mm with a thermal conductivity of 0.022w/mK.
