Rockwool Insulation Products

Insulation products based on innovative stone wool technology. Stone is the core raw material and the bedrock on which Rockwool is based. It is naturally resilient and essentially inexhaustible as the earth makes 38,000 times more rock every year (through volcanic and oceanic activity) than they use to make stone wool.
