Did you know?

Our stone wool is non-hygroscopic and moisture repellent. What's the difference? Moisture repellence means it is engineered to prevent water from penetrating the surface, while non-hygroscopic means it will not attract or absorb moisture from the surrounding environment. Both are important features in many of our products, including ROCKWOOL insulation, Rockpanel cladding and Rockfon acoustic tiles. 

ROCKWOOL stone wool insulation is designed to be water-repellant and does not absorb moisture.
