Introduction 

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 northestern Europe normal circumstances, this kg will save some 5 to 10 Mega joules 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.

Type: rock-wool board,rock-wool roll, rock-wool pipe

 

1. Rockwool board

 

Thermal insulation rock wool board is a board product with certain strength. The product is mainly applied for fire and sound proof in partition wall and wall curtain, thermal insulation in roof, retaining structure, floor heating system, industrial kiln, oven, large sized tank, as well as thermal insulation and fire proof of vessels, etc.
