Advanced rock wool production technology ensures low thermal conductivity and superior insulation performance, meeting strict building energy-saving standards and supporting green building certifications.
Breakthrough width of up to 2400mm reduces panel joints, accelerates installation timelines, lowers labor costs, and enhances overall wall stability.
Optimized fiber orientation delivers exceptional tensile strength, ideal for high-rise and super-high-rise buildings, resisting strong wind loads and extreme weather.
100% inorganic mineral fibers: non-combustible, no toxic gas emission, and no molten droplets during fires. Acts as a fire barrier, providing critical escape time.
High acidity coefficient ensures corrosion resistance and durability in humid or acidic/alkaline environments, maintaining performance for decades.
