105mm Rockwool Rainscreen Duo Slab Cladding

Discover 105mm Rockwool Rainscreen Duo Slab Cladding Insulation, engineered stone wool specifically for ventilated cladding and sealed curtain walling systems. Featuring Dual Density technology, this 105mm slab combines a robust outer layer for secure fixture points with a flexible inner core that accommodates substrate variations.

Once fitted, the denser outer face and factory-applied water-repellent coating work together to resist rain penetration during the construction phase. This adaptable 105mm Rainscreen Duo Slab accepts brackets and complex details with ease, and when positioned edge-to-edge, adjacent slabs lock together to create an unbroken thermal barrier, reducing energy loss through thermal bridging.
