is made of select fine basalt as the major materials which is pulled into 4-7µ non-continuous fibers after melted by adopting advanced international four-roller centrifugal cotton-making procedures and adding a certain of adhesives, dust laying oil and water repellent into rock wool fibers. It can be made into products series with different density according to various uses through the technology of sedimentation, solidify, cutting and etc.

advantages:

Application of rock wool:

Rock wool was used for building materials, and steel structure insulation

soundproof and fireproof used for wall and roof of house

Heat preservation for steel structure building

Heat Insulation for wall and roof of house to save energy

For indoor partition wall, Train compartment.

for ship thermal insulation and fire prevention partition keel interlayer sound insulation; Rock wool for building has excellent fire prevention, heat preservation and sound absorption performance. It is mainly used for building wall, roof insulation; Fire prevention and noise reduction of building partitions, firewalls, fire doors and elevator shafts.
