Description

URSA 35 Cavity Wall Batt is a non-combustible glass mineral wool insulation product designed for full or partial fill cavity wall applications in new external masonry construction. The batt is manufactured with a water-repellent additive to resist moisture ingress, helping protect the cavity environment.

Supplied at 455mm width, the product is engineered to fit between standard vertical wall tie spacings, allowing friction fitting without the need for on-site cutting. This reduces material waste and speeds installation on site. Each pack covers 2.46 square metres and is 150mm thick, delivering a thermal conductivity of 0.035W/mK.

The product holds British Board of Agrément (BBA) approval, confirming its suitability and performance for cavity wall insulation in UK building applications.
