Glass mineral wool slabs provide effective thermal and acoustic insulation for a wide range of residential, commercial and industrial building applications. Manufactured from lightweight glass mineral fibres, these insulation slabs help reduce heat loss, improve energy efficiency and minimise sound transmission between internal spaces.

We supply a range of glass mineral wool insulation slabs suitable for timber frame walls, metal stud partitions, internal walls, floors, ceilings and roof constructions. Their flexible structure allows them to fit between studs, joists and other framing systems, helping achieve consistent insulation coverage.

Our range includes products from recognised manufacturers such as Knauf Insulation and Isover, with different thicknesses, widths and thermal performance specifications to suit various project requirements.

Whether you are insulating a new-build property, upgrading an existing building or working on a commercial construction project, glass mineral wool slabs offer a practical solution for improving building thermal performance and acoustic comfort.
