Description

Soffitclad is a high-performance, non-combustible stone wool insulation board designed for soffit and exposed ceiling applications, delivering reliable thermal insulation, acoustic absorption, and fire resistance.

Manufactured from natural volcanic basalt rock, Soffitclad provides effective thermal performance and sound control within concrete soffits and exposed structural ceilings. It is particularly suited to open or semi-exposed environments where the insulation remains visible after installation, such as car parks, basements, service areas, and external overhangs.

To meet both functional and aesthetic requirements, Soffitclad is available with four surface finishes: unfaced (plain), white tissue facing, black tissue facing, and foil facing. These options allow the insulation to remain exposed while maintaining a clean, consistent appearance.

With a nominal density of 100 kg/m³ and a declared thermal conductivity of λ = 0.0364 W/mK, Soffitclad delivers efficient thermal insulation, and its open fibre structure provides excellent sound absorption (-50-62 dB). Soffitclad is classified as Euroclass A1 (non-combustible) and is suitable for buildings of any height, including high-rise developments, in accordance with UK Building Regulations.
