Rock-wool is a ceramic material conceived with fibres of molten stone. Compressed blocs of these woollike fibres are, since many years, used in construction industry as an insulating material

Its main features are its thermal insulation (low thermal conductivity), its non-combustibility and fire-resistance. In specific situations it is appreciated for its acoustic performances.

Rock-wool is an environmental-friendly material.

1 Kg of Rock-wool is conceived with an energy input of 10 to 20 Megajoules. Due to its insulating

capacity and used under for noth-western Europe normal circumstances, this kg will save some 5 to 10 Megajoules per month, depending on its application (thus a return on energy of 1 to 4 months).

In addition is rock-wool not a burden to the environment, as it is a natural and inert product and is rock-wool completely recyclable.
