75mm Rockwool Rainscreen Duo Slab

75mm Rockwool Rainscreen Duo Slab is a premium stone wool insulation solution engineered for ventilated cladding and sealed curtain walling systems. Featuring advanced Dual Density technology, this 75mm slab combines a robust outer layer for secure bracket fixings with a flexible inner core that adapts to substrate variations.

The denser outer surface incorporates factory-applied water repellent coating, delivering enhanced protection against rain penetration during the construction phase. This 75mm Rainscreen Duo Slab accommodates fixings and architectural details with ease, and when positioned side-by-side, the slabs interlock seamlessly to create a continuous thermal barrier that reduces unwanted heat loss through gaps.
