Hebei Xinxian Building Materials Co., Ltd.Waterproof Rock Wool Blankets: Engineered for Outdoor Projects, Rainproof with No Shape Distortion and Insulation Retention

Outdoor engineering, basement construction, pipeline laying, and other scenarios often face the erosion of rainwater. Standard rock wool tends to clump up and its thermal insulation performance significantly decreases when it comes into contact with water, even affecting the quality of construction work. Hebei Xinmian Building Materials Co., Ltd. has developed a waterproof rock wool blanket specifically for this purpose. With its superior waterproofing properties and stable thermal insulation effects, it has solved the problem of maintaining insulation in damp environments.

Core Waterproofing Technology of Water-Resistant Rock Wool Blankets

1. Double-layer protective structureThe core material utilizes hydrophobic rock wool with a water absorption rate ≤5%, covered with a high-density PE waterproof film on the outer layer, sealed with seamless heat pressing to prevent rainwater penetration.

2. Edge Sealing TreatmentAll seams are sealed with waterproof adhesive and double-stitched to prevent water from seeping in through gaps, offering comprehensive protection.

3. Excellent weather resistanceAfter undergoing high and low temperature cycling tests (-30℃ to 60℃), the waterproof film showed no cracking or peeling, maintaining its waterproof performance even after long-term outdoor exposure.
