Knauf OmniFit Slab 35 is a multi-purpose glass mineral wool insulation board designed for thermal and acoustic applications. Sized at 50mm thick, 1200mm long, and 400mm wide, it is dimensioned to fit directly between common timber or metal stud centres. This 5.76m2 pack contains 12 individual slabs, providing a versatile solution for reducing heat loss and sound transmission across different structural elements.
This insulation is applied by friction fitting the slabs between studs, joists, or rafters. This installation method prevents air movement around the edges of the material, minimising thermal bridging and infiltration. The OmniFit Slab is suited for use in ground floors, internal floors, internal partitions, pitched roofs at rafter level, and light steel frame walls.
A thermal conductivity of 0.035W/mK and an R-Value of 1.4m2K/W, meet standard thermal requirements. The glass mineral wool material is non-combustible with a Euroclass A1 fire rating. Furthermore, the slabs are compression-packed to allow more material per pallet, optimising storage, transport, and site handling.
- Friction fits between 400mm stud centres to prevent air infiltration.
- Achieves a Euroclass A1 fire rating for non-combustible performance.
- Delivers a thermal conductivity of 0.035W/mK to reduce heat loss.
- Made from glass mineral wool for combined thermal and acoustic insulation.
- Contains 12 slabs per pack to provide 5.76m2 of total coverage area.
