Rock wool sandwich full play to the unique properties of rock wool core material in thermal insulation, sound-absorbing insulation party has a significant effect. 1. Good thermal insulation: thermal conductivity of rock wool sandwich panel is mineral wool insulation properties of = 0.043W / ㎡K as the basis for a thickness of rock wool core material obtained corresponding ratio is calculated. 2. The sound-absorbing insulation effect is remarkable: insulation: rock wool sandwich panel for noise reduction deliver significant role, especially for a place designated by the flight. In addition, the use of rock wool roof, rain, hail on the roof of the building steel interior noise caused by the impact, but also significantly reduced. Through testing, in accordance with ISO717 / 82 and UNI 8270/7 standards, the choice of a density of 120kg / m3 rock wool as the core material of sandwich panels, insulation effect can be achieved RW = 29-30 dB acoustic: rock wool sandwich panel also has Excellent suction effect that can absorb sound within a relatively wide frequency range. According to ISO35 / 85 standard foam sandwich panels of wood, rock wool sandwich panel acoustic performance level reached DELTALA = 15.7dB (A).

Rock wool sandwich structure: 1) the upper and lower surfaces: galvanized steel sandwich panel color steel enclosure, a thickness of 0.4-0.8mm. According to the specific requirements of customers, but also can color galvanized steel or galvanized steel. After the first steel roll forming machine composite rock wool factory. 2) rock wool core material: the density of 120kg / m3 rockwool block interleaving laying its fiber direction perpendicular to the sandwich, the lower surface, and closely connected to enrich the entire vertical and horizontal surfaces of sandwich panels. And wool and, through high-strength adhesive foaming agent between the lower plate is formed integrally between rockwool block, sophisticated production process to ensure produce extremely high density rockwool insulation between the body and the metal plate inside wall strong adhesion, so that the rock wool sandwich panel has a good stiffness.
