Product description

Wallclad® 120 is a non-combustible stone wool insulation board designed for use within standard external wall insulation systems (EWI) and direct-render façade constructions. Manufactured from volcanic basalt rock, Wallclad 120 provides reliable thermal insulation, fire resistance, and acoustic absorption where insulation is installed directly to thin-coat or thick-coat render finishes.

Euroclass A1 (non-combustible) in accordance with BS EN 13501-1 reaction to fire
Declared thermal conductivity 0.0364 W/mK
Nominal density 120 kg/m³

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.

Application

WALLCLAD+®120 kg/m³ is specified across External Wall Insulation (EWI) constructions. Typical application areas include:

Thin-coat and thick-coat rendered external wall insulation systems (EWI)
Direct-surface render applications over masonry, concrete, or steel-frame structural walls
Adhesive-fixed and mechanically fastened standard façade cladding systems
Standard drained, unventilated, or ventilated external wall cavity constructions
New-build residential/commercial developments and standard external wall refurbishment projects
Buildings of any height requiring a stable, 120 kg/m³ high-density non-combustible insulation substrate
