This ISOVER Cavity Wall Slab is a glass mineral wool insulation slab designed for use in external masonry cavity walls, providing coverage in each pack. Sized at 1200 x 455 x 65mm, each slab is manufactured to fit between standard wall tie spacing for practical installation.
Typically used for cavity wall insulation on new build and refurbishment projects, this product helps reduce heat transfer and provides sound dampening. The slabs are suitable for both full fill and partial fill cavities, fitting easily into conventional wall construction layouts on site.
