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.
Discover the strengths of stone
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 noise and vibrations
Our stone wool products are high-density, which makes them extremely resistant to airflow and excellent at noise reduction and sound absorption, meaning that even the nosiest infrastructure sounds quieter.
We are in for the long-term
The inorganic property of stone wool makes it highly durable under any extreme climate conditions. It is dimensional stable and does not degrade over time.
The evidence shows that the performance of our stone wool remain unaltered for more than 40 years.
An ally to tackle important water issues
- 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 collect, buffer, transport and release water in the most optimal way.
We take a strong stand on circularity
We turn abundant raw materials and upcycled secondary materials into a range of long-lasting stone wool products. Owing to the ease with which they can be separated when a building is renovated or demolished, they can be transformed back into materials with commercial value, including via our take back services.
