Rockwool Sandwich Panel

Rock Wool Panels are consist of top and bottom PPGI, Zinc, Aluminum sheet, with high density basalt wool as core insulation. Due to the excellent performance fire resistance and acoustic insulation, rock wool sandwich panels are commonly adopted for fire-resistance and soundproof buildings.

Product Description

Rockwool sandwich panel is composed of two layers of outer color steel plates and an intermediate layer of rockwool. Rockwool sandwich panel is an excellent thermal insulation material. The most prominent advantage of rockwool is its excellent fire resistance, high flame retardancy and moisture absorption, and it is cheap and easy to install. It is widely used in various industrial plants, airports, gymnasiums, exhibition halls, hospitals and other commercial buildings such as exterior walls, roofs, interior partitions and ceilings.

Features of Rockwool Sandwich Panels:

• Fire retardant. Rockwool sandwich panel is fire retardant material and it has a high melting point, so in case of fire accident, it won’t develop or help to spread the fire. Aluminium has melting point at 660℃ while rock wool at around 1000℃

• Sound insulated. Rockwool sandwich panel has good sound insulation property. The non-directional structure of rock wool fiber helps to absorb the acoustic waves and reduce the airflow & sound transmission.

• Thermal insulated. Rockwool sandwich panel has excellent thermal insulation property. The rock wool reduces the airflow leading to a low heat conductivity.

• Sealing performance: Polyurethane double-sided sealing rock wool sandwich panel adopts the production line process, thus taking advantage of the excellent waterproofness of polyurethane products to overcome the shortcomings of rock wool easy to absorb water deliquescence, and effectively extend the service life of the product in terms of physical properties.

• Beautiful performance: The interface is designed according to European standards. The appearance is round and smooth, the surface is smooth and beautiful, the joints are tight, the strength is reliable, and the generation of cold and hot bridges is effectively prevented.

• Good rigidity: The polyurethane double-sided sealing rockwool core material is bonded to the two layers of steel plates to form a whole and work together, together with the corrugated pressure profile on the top surface of the roof panel, the overall stiffness is much better than that of the rockwool (glass fiber) Cotton) on-site composite sheet. After the sandwich panel is fixed to the purlin by the connecting piece, the overall rigidity of the roof is greatly improved, and the overall working performance of the roof is strengthened. The rock wool sandwich panel is selected, and a larger purlin distance can be used, so the amount of purlin can be saved by 1/3 ～ 2/3.

• The buckling method is reasonable: The two-sided polyurethane rockwool roof panels are connected by concealed buckles, which avoids the hidden leakage of the roof panel joints and saves the number of accessories.

• The fixing method is firm and reasonable: the polyurethane double-sided sealing rock wool roof panel is fixed with special M6 self-tapping screws and purlins, which can effectively resist external forces such as typhoons. Self-tapping screws are set at the peak position between the joints of the two panels of the roof panel, and a special waterproof structure is adopted to avoid weak points of waterproofing.

• Short installation cycle: Because there is no need for secondary processing on-site, the polyurethane double-sided sealing rock wool sandwich panel, not only can keep the surrounding environment tidy, does not affect the normal operation of other processes, but also can greatly shorten the installation cycle of the board. The daily installation area of rock wool sandwich panels is 600-800m2

• Anti-scratch protection: In the production of polyurethane double-sided sealing rock wool sandwich panel, polyethylene self-adhesive protective film can be pasted on the surface to avoid scratching or abrasion of the surface coating of the steel plate during transportation and installation.
