The D/Tie SF-Multi Cavity Closure 50-100mm is designed to close masonry cavities at openings such as doors, windows, and sills, helping to provide a clean edge while reducing cold bridging. Suitable for cavity widths between 50mm and 100mm, it offers a practical solution for sealing the cavity and improving overall thermal continuity within the wall construction.
Manufactured to suit standard site requirements, the closure incorporates an insulated core to help limit heat loss around openings. It is supplied in a 2.4m length, allowing it to be cut to size on site for straightforward installation across a range of cavity wall builds.
Designed for use in cavity wall construction, this multi-fit closure helps improve detailing around openings while supporting thermal efficiency. It is suitable for residential and commercial building projects where consistent cavity sealing is required.
