Soffit Slab is a cost-effective and fire-resistant thermal insulation solution designed for concrete soffits. The product is made from non-combustible Euroclass A1 ROCKWOOL® stone wool insulation and is available with a variety of optional facings, including black tissue, white tissue and aluminium foil.

In addition to providing thermal insulation and acoustic absorption, Soffit Slab is tested to provide up to 4 hours’ fire protection to concrete soffits.
