Description
Cavity closers are fitted within the cavity wall around doors and/or windows. By forming a seal within the aperture, they protect against water ingress and condensation, also acting as an effective DPC barrier and preventing thermal bridging.
Features and benefits:
- Available in two profiles to fit cavity widths: 50-100mm and 100–150mm.
- Simple to install, with cut-to-size grooves.
- Multi-width design overcomes cavity width variations.
Quality Standards:
- Manufactured in accordance with BS EN 13163: 2012 +A1: 2015.
- Satisfies all NHBC standards.
- Compliant with all relevant British Standards.
