5 cm 90 kg/m³ Rock Wool
Product Description
5 cm 90 kg/m³ rock wool is a high-density mineral wool insulation board designed to deliver outstanding thermal insulation, acoustic performance, and mechanical durability. Manufactured from natural basalt rock fibers, its 90 kg/m³ density provides excellent dimensional stability, allowing it to withstand wind loads and mechanical stress in demanding construction applications.
With a 5 cm thickness, this insulation board offers an effective balance of energy efficiency and space-saving installation. Its dense fibrous structure enhances both sound absorption and thermal performance, while its A1 non-combustible fire classification provides exceptional passive fire protection.
