Polyurethane edge sealed rock wool sandwich panel fully utilizes the unique properties of rock wool core material, and has significant effects in fire prevention, thermal insulation, sound absorption, and sound insulation; At the same time, it retains the advantages of polyurethane, such as plasticity, sealing, high strength, and non water absorption. The advantages of polyurethane and rock wool have been fully integrated, eliminating the shortcomings of traditional boards. In a sense, polyurethane edge sealed rock wool sandwich panels cannot be compared to ordinary rock wool sandwich panels.

Characteristics of polyurethane edge sealed rock wool sandwich panel:

(1) Sealing performance: The polyurethane edge sealing rock wool sandwich panel adopts an assembly line production process, which utilizes the excellent waterproof properties of polyurethane products to overcome the disadvantage of easy water absorption and deliquescence of rock wool, effectively extending the service life of the product in terms of physical properties.

(2) Aesthetic performance: The appearance is smooth and smooth, the board surface is flat and beautiful, the seams are tight, the strength is reliable, and it effectively prevents the occurrence of cold and hot bridges.

(3) Good stiffness: The polyurethane edge sealed rock wool sandwich panel is fixed to the purlins through connectors, greatly improving the overall stiffness of the roof and enhancing its overall working performance.

(4) Reasonable fastening method: The polyurethane edge sealed rock wool sandwich panel adopts a hidden nail and hidden buckle connection method, which avoids the hidden danger of water leakage at the joints of the sandwich panel and saves the amount of accessories used.

(5) Short installation cycle: Polyurethane edge sealed rock wool sandwich panel, as there is no need for secondary processing on site, can not only maintain the cleanliness of the surrounding environment without affecting the normal progress of other processes, but also greatly shorten the installation cycle of the panel.

Advantages of polyurethane edge sealed rock wool sandwich panel:

(1) Excellent fire resistance: The raw materials, production processes, and formulas used in polyurethane edge sealed rock wool sandwich panels give them excellent fire resistance.

(2) Good insulation performance: The insulation performance of polyurethane edge sealed rock wool sandwich panels is calculated based on the thermal conductivity of rock wool, which is 0.043 W/m2 K, and the thickness of the rock wool core material in the corresponding proportion.

(3) Significant sound insulation and absorption effect: Polyurethane edge sealed rock wool sandwich panel has a significant reduction effect on noise transmission.
