    Wider choice: URSA Cavity Batts, in a wide range of thicknesses, will assist in meeting the appropriate Building Regulation standard with any form of cavity wall construction.

    Quality: Outstanding product quality manufactured to ISO 9001 Quality Systems.

    User friendly: Our new generation URSA TERRA mineral wool has a ‘soft touch’ feel making it easier to handle and install whilst still maintaining its excellent mechanical properties.

    Environment: URSA mineral wool is manufactured from an abundant, sustainable resource and utilises at least 50% glass waste.

    Global warming potential: URSA Cavity Batts do not use chemical blowing agents and so the Global Warming Potential (GWP) arising from them is zero.

    Insulation savings: If a lightweight block is used for the inner leaf construction it is possible to meet the Building Regulation requirement with only 100mm URSA Cavity Batt.

    Adaptable: One product may be used for both full and partial fill systems

    Full fill systems: Minimal overall wall width and most cost effective for a given U-value. URSA Cavity Batts may be used in any exposure zone in buildings up to 25m high.

    Partial fill systems: The risk of wind driven rain penetration increases on exposed or coastal locations. The use of a residual 50mm clear cavity means URSA Cavity Batts may be used in any exposure zone.

    British Board of Agrément approval means that in many instances only a 25mm residual cavity need be maintained.

    Acoustic: URSA Cavity Batts have excellent sound insulation characteristics and enhance the acoustic insulation comfort of the building.

    Reduced risk of condensation: Walls fitted with URSA Cavity Batts create evenly warm conditions so reducing the risk of condensation.

    Effective below DPC: URSA Cavity Batts may be used below the damp-proof course in order to offer a degree of edge insulation to the floor.


    URSA Cavity Batts are lightweight yet tough, resilient and easy to install. They are easily cut using a sharp knife.


    URSA Cavity Batts are rot-proof, durable and maintenance free. They are non-hygroscopic and will not slump in normal use.
