100 to 150mm Multi Width Cavity Closer 2.4m

100 to 150mm Multi Width Cavity Closer 2.4m is a rigid plastic insulation closer for cavity walls, built for tradespeople who want quick, reliable closure with solid thermal performance.

Tailored on site with pre-cut grooves for 100–150mm cavities, it reduces waste and speeds installation. The continuous insulation fill minimises thermal bridging and works with masonry walls across a range of sizes.

Certified for Building Control and NHBC acceptance, it meets industry standards and is independently tested. The 2.4m length minimises joins, and the grooves guide easy cutting to fit odd openings. Download the YBS Easi-Close Technical Guide for fitting details.
