Rockwool, also known as mineral wool or stone wool, is a versatile fibrous insulation material manufactured from molten natural minerals and rocks. It is widely used for its excellent thermal insulation, high fire resistance and sound-absorbing properties, making it suitable for residential, commercial and industrial applications. The brochure states that it can withstand temperatures up to 1000°C.
KOOTS INSULATIONS supplies Rockinsul stone wool products for building, HVAC and industrial insulation requirements, including building rolls, slabs, LRB mattresses and pipe insulation.
Why Choose Rockinsul Rockwool?
Excellent Thermal Insulation
Rockwool provides effective thermal insulation, helping reduce heat transfer across walls, equipment, ducts and industrial surfaces.
High Fire Resistance
Stone wool offers excellent resistance to high temperatures and is suitable for applications where fire performance is an important consideration. The brochure specifies resistance up to 1000°C.
Sound Absorption
The fibrous structure of Rockwool provides sound-absorbing properties, making it suitable for acoustic insulation and noise-control applications.
Versatile Applications
Rockinsul products are available in different forms for building, HVAC, equipment, duct, pipe and industrial insulation requirements.
