Nowadays, the designer engineer has in his disposal a variety of materials which enables him to choose the most suitable for the targeted application – either building or industrial – taking into account of a number of parameters such as: thermal insulation requirements, operating temperatures, levels humidity, cost and aesthetics. Therefore, to characterize a material it is necessary to examine the multifaceted and not focus on a single feature. That is incorrect perceivable as a heat insulating material is “good” because it has a low coefficient of thermal conductivity.
Fire Resistance
The thermal insulating panels (stone-wool panels) are used for side covering or partitions (fire compartments) of metal buildings with thermal insulation requirements and high demands of fire resistance and sound insulation.
Acoustic insulation
The combination of mineral wool fibers contain large percentage of free space ( air) that even when compressed in rolls or sheets, mineral wool has excellent insulation properties.
Thermal Insulation
The stone wool products have a coefficient of thermal conductivity (k) between 0,03 and 0,04 W / mK at room temperature.They can be used in industrial applications extremely high temperatures , such as superheated steam networks and foundries or even in space applications.
Ecology
Stone-wool comprises a mass of ultra- fine fibers , whose diameter is no more than 4 or 5 microns . The fibers are from 100 % recyclable blend of rocks that abound in nature: volcanic rocks , limestone , dolomite and bauxite.
