INSULATION MINERAL WOOL

What is mineral wool insulation?

The term mineral wool is used to describe insulation made from minerals. This includes stone, silica and other materials that are extremely resistant to heat. The raw materials are heated to a high temperature and, once molten, spun into fibres. These fibres are then formed into finished insulation products, such as slabs, rolls, pipe sections and loose wool or granulate.

Two of the most common types of mineral wool are stone wool, made from volcanic rock, and glass wool, which is made from silica or glass cullet. Glass wool is also referred to as glass fibre.

ROCKWOOL stone wool insulation is made from abundant deposits of naturally occurring basalt volcanic rock, together with recycled and upcycled secondary materials. ROCKWOOL is our brand name, but the term is sometimes used interchangeably with rock mineral wool or stone wool. Only we make ROCKWOOL stone wool insulation.
