Sealing performance: rock wool sandwich polyurethane seal on both sides with a rock wool insulation board assembly line production process to take advantage of the excellent water resistance of polyurethane products to overcome the disadvantage of deliquescence easy-absorbent wool rock wool insulation board manufacturer, in the physical properties extend the effective life of the product. Beautiful performance: interface with European standards for the design, the appearance of smooth rounded rock wool insulation board processing, the board smooth and beautiful, tight joints, reliable strength, effectively prevent cold bridges. Since the installation of discharge line pressure plate roof and wall panels are prefabricated structure, so put lines Before installation of the post-installation quality assurance role to play rock wool insulation MILL, can not be ignored. Pre-installation deal with the mounting surface of the discharge line has finished building measure, fail to meet the installation requirements of section propose changes. A record of the construction deviations and propose appropriate measures for the installation error.
