Lightweight semi-rigid glass-mineral wool batts for cavity wall systems

Product Overview

Designed for both fully-filled and partial cavity wall systems (up to 25 m building height), URSA 32 Cavity Insulation offers an efficient, flexible and long-lasting solution for thermal and acoustic performance. It’s manufactured using up to 80% recycled glass waste and carries zero global-warming potential, making it a smart choice for sustainable construction.

Key Features & Benefits

• Excellent acoustic insulation performance, enhancing comfort levels within the building.

• Helps reduce condensation risk and provides warmer internal conditions.

• Low vapour resistance allows the wall cavity to breathe and manage moisture effectively.

• Maintenance-free with a service life equal to that of the building structure.

• Manufactured under ISO 9001 quality systems, with Euroclass A1 fire rating to BS EN 13501-1.

• Environmentally friendly production using up to 80 % recycled glass content.

Applications

• Full-fill cavity wall systems: Suitable for buildings up to 25 m high in any exposure zone.

• Partial-fill cavity wall systems: Suitable with a residual clear cavity (minimum 25 mm; 50 mm preferred in coastal or exposed zones) to ensure wind-driven rain protection.

Installation Guidance

• For full-fill applications, build the outer leaf with the first row of wall ties at 600 mm centres, then install the URSA batts as the wall progresses.

• For partial-fill systems, fix batts to the cavity face of the inner leaf using wall ties or retaining clips, maintaining a clear cavity and staggering joints.

• Keep cavities free from debris and mortar droppings, especially around slab edges and cut sections.
