In a structural soffit floor, insulation is required for thermal, fire safety and acoustic performance to enhance the comfort of the habitable space above the soffit floor.
Sometimes, aesthetics are an important consideration, and a rock mineral wool board can be combined with a wood wool panel or an alternative facing to improve the appearance of the soffit area.
Whatever your requirement, we have a range of non-combustible options, with different finishes available.
