Wool made of stone
Stone wool is literaly wool made of stone. It can occure naturaly around volcanos. When molten lava is slung around at high speeds, it forms into small fibres. By nature, these fibres tend to flock around in tuffts that can be found hanging on the braches of trees around these volcanos. At ROCKWOOL, we have more than 80 years experience of mimicing this natural process. We use the tamed volcano principle to melt natural stones together with secondary raw materials. The lava is spun into fibres that are collected and shaped into different products. A resin is used to bind the fibres together. The resin that we use is durable and does not give off toxic gasses during a fire.
Features of stone wool
We keep it cool when things get hot
ROCKWOOL stone wool can withstand temperatures up to 1000°C. It is non-flammable and doesn't produce significant toxic smoke.
We protect you from unwanted noises & vibrations
We are in for the long-term
The inorganic property of stone wool make it highly durable under any extreme climate conditions.
The evidence shows that the acoustic and mechanical performance of our stone wool mats remain unaltered for more than 40 years.
We provide you safe solutions with lower lifetime maintenance and total ownership cost.
Our raw material is one of the must abundant on the planet
While the oceans cover 71% of the Earth’s surface, they only account for 0.02% of our planet’s total mass
An ally to tackle important water issues
At ROCKWOOL we engineer stone wool with 2 distinct technologies.
- We can create products with water repellent properties that can keep you dry and protect you from humidity.
- Or alternatively offer you a wide range of solutions that can absorb, store, transport and release water in the most optimal way.
Different applications require different shapes of the stone wool. The default shape that is produced on the production line is rectengular in sizes of 50 - 200 cm (length & width) and 4 - 20 cm in thickness.
From these products, we can cut many different shapes like cylinders, cubes, strips or even freeform, where holes are cut or drilled into the slabs.
