90mm Rockwool Rainscreen Duo Slab

Introducing 90mm Rockwool Rainscreen Duo Slab Cladding Insulation, a premium stone wool solution engineered for ventilated cladding systems and sealed applications including curtain walling. Featuring Dual Density technology, this 90mm slab combines a robust outer layer for secure fixings with a flexible inner core that adapts to surface variations.

Once fitted, the reinforced outer surface paired with factory-applied water repellent coating provides superior protection against rain penetration during the construction phase. This adaptable 90mm Rainscreen Duo Slab readily accommodates brackets and complex architectural features, and when positioned tightly, neighbouring slabs lock together to create a unified thermal barrier that reduces heat escape through joint areas.
