125mm Rockwool Rainscreen Duo Slab Cladding

Discover 125mm Rockwool Rainscreen Duo Slab Cladding Insulation, engineered specifically for ventilated cladding and sealed systems including curtain walling applications. This stone wool insulation features Dual Density technology, combining a robust outer layer for secure fixings with a flexible core that adapts to substrate variations.

Once installed, the denser outer surface paired with factory-applied water repellent coating provides enhanced protection against rain penetration during the construction phase. This 125mm Rainscreen Duo Slab accommodates brackets and complex detailing with ease, and when positioned tightly together, adjacent slabs lock seamlessly to create a continuous thermal barrier that reduces unwanted heat loss through gaps.
