Summary
A cavity closer for fire, thermal and acoustic insulation.
A cavity closer for fire, thermal and acoustic insulation.
Application
Designed to be used for masonry cavity wall construction. Suitable for vertical and horizontal application.
Designed to be used for masonry cavity wall construction. Suitable for vertical and horizontal application.
Description
A cavity closer for thermal, acoustic and fire insulation, which reduces cold bridging when used for door and window openings. It consists of a strip of engineered stone mineral wool insulation laminated to a polythene DPC. It is produced in a range of sizes to fit cavity widths up to 100mm within masonry systems.
Features and benefits:
- Thermal bridging solution.
- Range of sizes available.
- Provides insulation against the passage of fire through wall cavity.
- DPC to BS 6515.
- Suitable for horizontal and vertical applications.
Mayplas FR Reveal Cavity Closer has been independently tested in accordance with BS EN 1366-4:2021 and classified in accordance with BS EN 13501-2:2023 for 120 minutes Integrity and 60 minutes insulation (vertically) and 15 minutes insulation (horizontally)
