Product description

Soffitclad® White Tissue is a non-combustible stone wool insulation board featuring a clean white tissue facing, designed for exposed soffits, pedestrian undercrofts, and multi-story car park applications. Manufactured from volcanic basalt rock, it provides reliable thermal insulation, fire resistance, and acoustic absorption within open public zones and structural ceiling areas. The white tissue finish dramatically enhances light reflectance and provides a neat, uniform, and visually bright appearance where the insulation remains fully visible after installation. With a structural nominal density of 100 kg/m³ and a declared thermal conductivity of λ = 0.0364 W/mK, Soffitclad White Tissue delivers high-performance thermal protection along with exceptional acoustic performance. Featuring a premium Euroclass A1 non-combustible stone wool core, it is fully certified to meet the highest safety and fire compliance standards for public and commercial builds.

Euroclass A1 (non-combustible) in accordance with BS EN 13501-1 reaction to fire
Declared thermal conductivity 0.0364 W/mK
Nominal density 100 kg/m³

Application

SOFFITCLAD®White Tissue is specified across Soffit Applications constructions. Typical application areas include:

Multi-story, open-sided, and underground commercial car park ceilings
Exposed public pathways, pedestrian undercrofts, and structural transition zones
Visible structural ceilings requiring high uniform light reflectance and room brightness
Open overhead zones demanding a clean, bright, and visually complete pre-finished appearance
Exposed concrete soffits left fully visible post-installation without secondary plastering
Buildings of any height requiring white-finished non-combustible public soffit insulation
