Rockwool Ventirock

VENTIROCK is a stone wool thermal insulation board with a very high nominal density, that guarantees non-combustible insulation for walls with panelled, stone and glass façades as well as frame walls, curtain walls, partition walls and three-layer structures. It is a single-density product that is used where façade safety matters. With the highest reaction to fire class A1, it guarantees the fire safety of the building. Thanks to the declared absorbency WS and WL(P), problems of wetting during works are minimized. With its very good thermal performance and resistance to moisture and fire, it is the best alternative where glass wool is to be used.
