Features of rockwool roof sandwich panel:
1. Good rigidity: Because the rock wool core material is bonded to the upper and lower steel plates into a whole, working together, plus the roof ridge pressing profile on the upper surface of the roof panel, its overall rigidity is far better than that of the on-site composite plate. After the rockwool roof sandwich panel is fixed with the purlins through the connectors, the overall rigidity of the roof is greatly improved and the overall working performance of the roof is strengthened. The use of rock wool sandwich roof panels, can use a large purlin spacing, so can save one-third to two-thirds of the purlin’s dosage.
2. Reasonable lap connection method: the rockwool roof sandwich panel adopts the lap connection method, which avoids the hidden danger of water leakage in the joints of the roof panel and saves the number of accessories.
3. The fixing method is firm and reasonable: the rock wool roof sandwich panel is fixed by self-tapping screws and purlins, which can effectively resist external forces such as typhoons. The self-tapping screws are set at the crest position of the upper surface of the roof panel, and a special waterproof structure is adopted to avoid waterproof weak points.
4. Short installation cycle: due to the rock wool roof sandwich panels has no on-site secondary processing, not only can keep the surrounding environment clean, does not affect the normal progress of other processes, but also can greatly shorten the installation cycle of the board, rock wool roof ppgi sandwich panels daily average installation area of 600-800 square meters.
5. Surface protection: When the rockwool sandwich panel is produced, the surface has been pasted with poly PE protective film, which can to avoid scratches or wear on the surface coating of the steel plate during transportation and installation.
Performance indicators of rock wool roof sandwich panels:
1. Excellent fire performance: the raw materials, production technology and formula used in rockwool roof sandwich panel make it have good fire performance. Tests have shown that it has a fire resistance of more than 1000°C. Rock wool sandwich panels can meet Class A fire protection standards.
2. Good thermal insulation: the thermal conductivity of rock wool is 0.043W/㎡·K, compared with ordinary brick walls, the thermal insulation ability is strong.
3. The sound absorption and heat insulation effect are remarkable:
◆Sound insulation: rock wool roof ppgi sandwich panels has a significant attenuating effect on noise transmission, especially suitable for places with large noise. In addition, after the use of rock wool roof panels, the indoor sound caused by rain and hail on the roof steel plate of the building is also significantly weakened.
◆Sound absorption: ppgi sandwich panels roof also has excellent sound absorption effect; it can absorb a wide range of sound.
