Sealing performance: rock wool sandwich polyurethane seal on both sides with a rock wool insulation board assembly line production and processing technology to take advantage of the excellent water resistance of polyurethane products overcome the shortcomings of easy-absorbent deliquescence of Anyang wool rock wool insulation board manufacturers in physics performance effectively extending the life of the product. Beautiful performance: interface with European standards for the design, the appearance of rounded and smooth, flat plate surface appearance, tight joints, reliable strength, effectively prevent cold bridges. Rock wool sandwich polyurethane seal on both sides give full play to the unique properties of mineral wool core rock wool insulation board manufacturer, in fire protection, thermal insulation, acoustic insulation and other aspects have a significant effect; while retaining polyurethane plastic, closed, high-strength, non-absorbent advantages. The advent of this material is a revolutionary change in construction projects, making polyurethane, rock wool advantages have been fully converged, reject the existence of the shortcomings of traditional sheet. In a sense, both sides sealed wool polyurethane sandwich panels can not be compared with ordinary wool sandwich.
