Stone wool insulation is made in large part from volcanic rock. Stone wool insulation is incredibly durable and will last the lifetime of the building. Because stone doesn’t burn, this insulation is incredibly fire-resistant. It is also tremendously effective in keeping out noise, again because of its rock-based properties. Stone wool insulation has nearly unmatched capabilities in shielding from weather temperatures, fire and noise.
