With the rapid development of the construction industry in recent years. Rock wool boards are widely used in the construction industry, and there are plans to expand production on a large scale. The market for the development of building insulation materials is huge. As the main building insulation material, rock wool board can be used not only for roofing, but also for exterior walls. So is the high-strength roofing rock wool board waterproof?

　　Rock wool is a high-quality and efficient thermal insulation material. The production process of rock wool board is generally to melt rock or glass at high temperature, then make inorganic fibers through high-speed centrifugal equipment, and add a certain proportion of binder, dust-proof oil and silicone oil. , and then made into boards according to different requirements. It has excellent thermal insulation performance, mechanical performance, sound absorption performance, easy installation, long service life and low price. It is an ideal thermal insulation material recognized at home and abroad.

　　High-strength roof rock wool board is a rock wool product designed and developed for various flexible waterproof roof systems. Water and moisture-proof performance, can meet the needs of the roof system construction and maintenance and the weight of related equipment. Rock wool board is often used in construction, petroleum, electric power, metallurgy, textile, national defense, transportation and other industries, insulation and sound insulation of pipeline storage tanks, boilers, flues, heat exchangers, fans, vehicles, ships and other industrial equipment.

　　Roof rock wool board has super waterproof performance because a water repellant is added to the rock wool board. In the natural state, the lower moisture absorption rate ensures better thermal insulation performance. The water repellency rate of Uetersen rock wool products: ≥ 99% higher water repellency rate, ensuring consistent performance in wet or watery environments. Whether it is applied to the exterior walls or roofs of buildings, it can well meet the waterproof and moisture-proof functions. Not only that, the application of rock wool board to the building can also effectively prevent the interior of the house from getting damp, making the whole room drier and fresher.
