150mm URSA 35 Cavity Insulation Batt - 1350mm x 455mm (pack of 4)

150mm URSA Cavity Batt 35 is a high‑quality glass mineral wool insulation slab manufactured for use in partial‑fill cavity wall systems in residential and commercial buildings. The slabs are semi‑rigid, allowing them to friction‑fit securely between wall ties, reducing gaps and minimising thermal bridging.

With a thermal conductivity of 0.035 W/mK, the product provides reliable thermal insulation while maintaining a competitive price point. The mineral wool is water‑repellent, ensuring that moisture from the cavity does not penetrate or compromise the insulation layer.

URSA Cavity Batt 35 is Euroclass A1 non‑combustible, offering the highest level of fire performance for external wall build‑ups. It also delivers excellent acoustic absorption, improving internal comfort by reducing airborne sound transmission. The slabs are lightweight, easy to cut and simple to install using standard tools.
