Rockwool Rainscreen Duo Slab

Rockwool Rainscreen Duo Slab is a dual-density stone wool insulation product specifically developed for use within ventilated cladding systems, as well as sealed systems such as curtain walling.

Once installed, the robust outer surface of the slabs, in combination with a factory-applied water-repelling agent, acts to resist rain ingress during construction.

To ensure a safe living and working environment, we recommend using Rockwool Rainscreen Duo Slab in combination with Rockpanel A2 (FS-Xtra).

These Euroclass A-rated Rockwool Rainscreen Duo Slab products are for ventilated rain screen systems are a popular choice for multi-unit residential blocks, office blocks, hospitals, schools, hotels and multi-use developments.

It can be easily fitted around brackets and other details, and when tight butt jointed the fibres of adjacent slabs will knit together to provide a continuous thermal performance

Eliminating heat losses that could otherwise be caused by gaps and joints.

A water-repelling agent is added to the product during manufacture, which in combination with a robust outer surface and random fibre orientation, prevents water transmission through the insulation layer.

There is no doubt that Rockwool Rainscreen Duo Slab is the best choice for use in severe climate conditions. It can accommodate irregularities in the substrate due to its resilient inner face.

As such the slab is well-designed for use in conditions of severe climatic exposure.
