Cavity closures are used to seal wall cavities around window and door openings, preventing thermal bridging, moisture ingress and air leakage. Installed as part of cavity wall construction, they contribute to improved energy efficiency and airtightness. Commonly specified in new builds and retrofit projects, cavity closures support compliant detailing and long-term building performance.
