How and Where Is Rockwool Manufactured?
24 March 2022
The process of making Rockwool insulation slabs begins by heating the rock until it becomes molten. This is then made into a wool that is spun into fibres. These rock fibres are poured into moulds to create the insulation slabs.
Finally, the slabs are cooled and cut to size. Rockwool has different ranges and sizes, at Materials Market we sell;
- RWA45 – 25mm, 50mm, 75mm, and 100mm
- Flexi Slab – 50mm, 100mm, and 140mm
- RW3 – 50mm, 75mm, and 100mm
- RW5 – 100mm
The 100mm of each range is typically the most popular.
Rockwool insulation is manufactured in a few different countries, including Denmark, Sweden, and the United States. In the United States, Rockwool insulation is made in South Carolina.
The manufacturing process for Rockwool insulation is environmentally friendly because it does not produce any harmful emissions. Additionally, Rockwool insulation is made from a natural resource and can be recycled.
At their production plants, they are actively working to improve and refine the manufacturing process so that it leaves even less of an imprint on the environment. For example, the plant in Horsens, Denmark is CO2-neutral, meaning that the amount of CO2 released into the atmosphere from the production of Rockwool equals the amount of CO2 removed by the plant’s green energy installations.
Rockwool insulation is an excellent thermal insulation material because it has a low thermal conductivity value and does not absorb moisture. It is also resistant to fire, pests, and mould.
Rockwool insulation is a popular choice for residential and commercial buildings because it is effective, safe, and has an excellent acoustic performance. It is also easy to install and does not require any special training.
