Rockfibre SA Pty Ltd started producing Rockwool products in 2008 at their plant in Powerville Vereeniging. Rockwool is produced from a Diabase rock mix to create fibrous insulation products.
A range of products are produced to suit the industrial insulation needs and conform to require specifications in South Africa and aboard. The products were designed for a wide temperature range for thermal applications as well as acoustic insulation.
Rockfibre products are manufactured generally in accordance with BS3958.
Rockfibre insulation offers several key advantages for industrial applications. It reduces heat loss, helping to save energy and lower running costs. The material maintains controlled temperatures and lowers surface temperatures, enhancing personnel protection. It also minimizes random temperature influences from external sources. Additionally, Rockfibre insulation effectively suppresses and absorbs noise in industrial environments.
Rockfibre products are made from non-combustible mineral fibres with inherently low levels of water-leachable chlorides, ensuring long-term performance and safety. According to the International Agency for Research on Cancer, Rockwool is not classifiable as to carcinogenicity to humans and is considered a non-hazardous material to work with.
