For use in cavity wall constructions of widths from 50 mm upwards.

A range of insulated, fire-resistant and BBA approved and cavity closers.

Features and benefits:

• The products are designed for use at door and window openings, providing a damp proof barrier between inner and outer wall leaves without forming a thermal bridge.
• Can accommodate standard window reveals and rebated check reveals.
