Frequently Asked Questions
What is stone wool?
Also known as mineral wool or rock wool, stone wool is created by spinning a molten stream of rock, steel furnace slag and recycled materials. Made principally from volcanic rock, it is comprised of 70% natural raw materials including basalt, dolomite and similar rocks, which are generally melted in a cupola furnace with a carbon-containing energy source using optimal energy and environmental protection recovery systems.

Why choose stone wool?
Stone wool can be used for insulation and fire protection in many applications. It is particularly suitable for industry given its high temperature resistance and non-combustibility. Click here to learn more.
Stone wool insulation or glass wool insulation?
The advantage of stone wool over glass wool is its resistance to high temperatures, making this type of insulation the safest in term of fire prevention.
But did you know that there a stone wool that combines this fire resistance with lightweight? Click here to learn more.
How is ULTIMATE U-Sea protect made?
The patented process for manufacturing ULTIMATETM is similar to that used for glass wool. However, the challenge for our development team was to develop a product capable of operating at much higher temperatures. This was achieved following a breakthrough involving a new patented glass composition and extensive conversion of the basic glass wool manufacturing process. Click here to learn more.
