Thermal insulation: Crafted with long, thin rock wool fibers and minimal slag ball content, this material offers superb thermal insulation with low thermal conductivity.
Hydrophobicity & Moisture Resistance:Achieving a hydrophobicity rate exceeding 99%, it ensures no minute penetration and maintains a very low hygroscopic rate.
Sound Absorption & Noise Reduction:The interconnected porous structure formed by elongated fibers delivers notable sound absorption and noise reduction properties.
Easy Construction:Lightweight, easy to transport, and simple to cut, ensuring high stability during installation.
Superior Heat Preservation: Anti-frost, freeze-thaw resistant, and UV stable, it prevents thermal expansion and contraction across varying seasonal temperatures.
Non-corrosive:Exhibiting stable chemical properties with a pH value of 7-8, it does not corrode steel, aluminum, or other metals.
Environmentally Friendly: Free from asbestos, CFCs, HFCs, and other harmful substances, making it an eco-conscious choice.
