A high-performance, non-combustible A1 stone wool insulation with black tissue facing for open-joint and shadow-gap ventilated rainscreen façade systems.
Dimclad® is a non-combustible stone wool insulation board designed for use within open-joint and shadow gap ventilated rainscreen façade systems. Manufactured from volcanic basalt rock, Dimclad provides reliable thermal insulation, fire resistance and acoustic absorption within external wall constructions.
The product incorporates a factory-applied hydrophobic treatment and a durable black mineral fibre tissue facing to reduce water absorption during installation and provide UV stability behind open joints, while maintaining vapour permeability within the wall build-up. With a nominal density of 60 kg/m³ and a declared thermal conductivity of λ = 0.035-0.039 W/mK, Dimclad delivers high-performance thermal insulation suitable for modern façade systems.
Dimclad insulation is suitable for buildings of any height, including those exceeding 18 metres, when used within compliant non-combustible façade constructions.
