Rockwool is made from basalt, an inorganic raw material, which is obtained domestically. It is produced through heating basalt at 1350˚C – 1400˚C and transforming it into fibres. It can be manufactured in the forms of blanket, board, pipe or loose in different size and with different technical properties, with different facing materials according to the intented use and the place of use. It is used for thermal insulation, sound insulation, acoustic comfort as well as fire safety.
- Its declared thermal conductivity is 0,035 ≤ λ ≤ 0,040 W/mK. (at 10˚C)
- Depending on the declared thermal conductivity values, RockWool products are in the thermal conductivity groups of 035 and 040.
- Water vapour diffusion resistance factor μ = 1.
- Depending on the product type, the temperature of use is between -50/+650˚C. Melting temperature > 1000˚C.
- Even if it is subjected to heat and humidity it stays dimensionally stable.
- It is rot proof and resistant to aging. It does not corrode, decompose or allow mold formation. They are resistant against insects and microorganisms.
- It is not hygroscopic and capillary.
- Unfaced rockwool products are classfied as “A1” group noncombustible materials with respect to TS EN 13501-1.
