Hebei Xinmian Building Materials Co., Ltd. Waterproof Rock Wool Blanket

Hebei Xinmian Waterproof Rock Wool BlanketWaterproof Rock Wool Blankets: The Preferred Waterproof and Insulation Solution for Outdoor Projects, Passing 72-Hour Water Immersion Test Outdoor projects, such as bridge maintenance, infrastructure outdoor equipment, and temporary material sheds, are often exposed to rain and snow for extended periods. Standard rock wool blankets are prone to absorbing moisture, which drastically reduces their insulation properties and can even lead to equipment freeze damage and concrete cracking. Hebei Xinnian Building Materials Co., Ltd. has been dedicated to the research and production of waterproof rock wool blankets. Their products, with their superior waterproofing and stable insulation properties, have become the "protection shield" for outdoor projects' insulation. I. Core Technology of Waterproof Rock Wool Blankets: Solving the Problem of Moisture Double-layer waterproof structure, blocking rain and snow penetration:Hebei Xinnian Building Materials Co., Ltd.Waterproof rock wool is adopted with a "double-layer protection design of high-density waterproof film + waterproof coating." The outer waterproof film has a thickness of 0.3mm, which can directly block the penetration of rain and snow. The inner layer is added with a hydrophobic coating, allowing for rapid drainage and expulsion of any moisture that comes into contact with the core material, preventing the core from getting damp. Officially tested and certified, with guaranteed performance: The product has passed the water spray test at the National Building Materials Testing Center, simulating a heavy rain environment for 72 consecutive hours (80mm/h rainfall), with the core moisture content consistently below 5%, and thermal insulation performance dropping only by 3%, far exceeding the industry standard of 10% moisture content. Combining thermal insulation and waterproofing, no additional covering is needed: Compared to the traditional combination of "common rock wool blanket + plastic cloth",Hebei Xinmian Building Materials Co., Ltd.Waterproof rock wool panels eliminate the need for additional waterproofing membrane, reducing construction processes while avoiding issues such as wind-raised or damaged plastic sheets leading to ineffective waterproofing. Case Study of Outdoor Engineering Applications: A bridge maintenance project in Hebei during the winter of 2024 witnessed the product's strength.Hebei Xinmian Building Materials Co., Ltd.Waterproof rock wool blanket covered and maintained, enduring three snowfalls consecutively; after the snowmelt, the rock wool blanket showed no leakage; the concrete curing temperature remained above 15°C, with no signs of cracking due to freezing. Outdoor equipment insulation project: A chemical company's outdoor storage tank used...Hebei Xinmian Building Materials Co., Ltd.Waterproof rock wool insulation ensures that the internal medium of the storage tank remains unfrozen in low-temperature winter conditions, allowing equipment to operate normally, saving approximately 20,000 yuan in annual thermal maintenance costs. Hebei Xinxian Building Materials Co., Ltd. offers free sample testing services for waterproof rock wool blankets, allowing outdoor engineering customers to test the waterproof performance before making a purchase decision, ensuring that every investment is protected.
