A high-performance, white tissue-faced stone wool insulation board providing high light reflectance and a clean finish for multi-story car parks and open undercrofts.




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