Cavity Closer - 50 - 100mm 2.4m

Cavity Closer 50–100mm 2.4m is a durable building component designed to close and seal cavity wall openings around doors, windows and other apertures in masonry construction. It helps to prevent cold bridging, moisture ingress and air leakage, improving overall thermal performance and building efficiency.

Manufactured from rigid, insulated materials with an integrated damp-proof barrier, it provides a neat and effective solution for maintaining cavity integrity at openings. The adjustable 50–100mm range makes it suitable for a variety of cavity widths, offering flexibility across different wall constructions.
