Hush Lag 5/25 is a high-performance acoustic laminate designed to provide effective sound attenuation across a wide range of building and mechanical service applications. Size on the Roll 2 x 1.2 x 25mm Manufactured as a stable tri-layer construction, it combines a controlled density mineral fibre layer, a flexible high-mass acoustic barrier and a reinforced foil facing. The integrated design delivers both mass and isolation within a single material, removing the need for a separate decoupling layer. The outer foil finish provides additional durability along with flame and vapour resistance. The fire performance of the product is tested as B, s2, d0 (Test Ref: 27/06787B3/06/25). This makes the material suitable for use in environments where this level of fire performance, acoustic performance and mechanical protection are required.
