100mm Rockwool Rainscreen Duo Slab

Discover 100mm Rockwool Rainscreen Duo Slab Cladding Insulation, a premium stone wool solution engineered for ventilated cladding systems and sealed curtain walling applications. Featuring Dual Density technology, this 100mm slab delivers a reinforced outer layer for secure bracket fixings, paired with a flexible inner core that adapts to uneven substrates.

The denser outer surface combines with factory-applied water repellent treatment to provide superior protection against rain penetration during the construction phase. This 100mm Rainscreen Duo Slab accommodates brackets and complex architectural details with ease, and when positioned edge-to-edge, adjacent slabs lock together to create a unified thermal barrier that reduces unwanted heat escape through gaps.
