A premium, high-density non-combustible A1 stone wool insulation board with a 140 kg/m³ density, optimized for structurally bonded brick slip systems and high-impact façade constructions.




Wallclad® 140 is a high-density, non-combustible stone wool insulation board designed for heavy-duty external wall insulation systems (EWI) and heavy façade constructions. Manufactured from volcanic basalt rock, Wallclad 140 provides reliable thermal insulation, fire resistance, and superior acoustic absorption where the building envelope demands enhanced mechanical strength and impact resistance.
Engineered as a high-density board for rendered external wall insulation (EWI) and direct-bonded façades — including brick slip and heavy masonry finishes. For project-specific densities or thicknesses, talk to our technical team.
WALLCLAD+®140 kg/m³ is specified across External Wall Insulation (EWI) constructions. Typical application areas include:
