Mineral insulation derived from the fusion of volcanic rocks. Offers a unique combination of thermal insulation, excellent acoustic absorption and passive fire protection (Class A1).
Multi-function insulation principle. The fibrous mass blocks heat and dissipates acoustic energy through friction. Melting point above 1150 degrees C ensures passive fire compartmentation.
From the melting of basaltic rock a material is reborn that protects living spaces. Rock wool is not merely a thermal insulator, but a mineral barrier against fire and noise, a pillar of contemporary building safety.
Production emulates volcanic activity: natural rocks such as basalt, dolomite and diabase are melted in furnaces at over 1500 degrees C. The molten rock is spun to obtain very fine fibres, then moulded into rolls or panels. Being open-structured (mu=1), rock wool does not retain vapour, allowing walls to breathe and avoiding interstitial condensation.
Unlike synthetic insulators (EPS, XPS, PU), rock wool is incombustible (Euroclass A1). It does not contribute to fire, does not drip and emits no toxic fumes, withstanding temperatures above 1000 degrees C. Acoustically, its fibrous nature acts as a sponge for sound waves, dissipating them within the mineral weave.
European and international references applicable.
Rock wool is mandatory on facades above certain heights where combustibility of external insulation is restricted. On breathable historic masonry, its mu=1 value prevents interstitial condensation.
