70mm Rockwool NyRock Rainscreen 032

70mm Rockwool NyRock Rainscreen 032 is a premium stone wool insulation solution engineered for ventilated cladding systems and sealed applications including curtain walling.

Utilising proprietary technology, this 70mm slab incorporates an optimised fibre matrix that enhances air pocket density, delivering exceptional thermal performance beyond standard stone wool insulation alternatives.

Once installed, the high-density structure combined with a factory-applied hydrophobic coating provides excellent protection against moisture ingress during the construction phase.

Installation is straightforward, with the product accommodating fixings and architectural features without difficulty. When positioned closely together, slabs bond seamlessly to create a continuous thermal barrier, substantially reducing thermal bridging through gaps.
