Product DescriptionProduct DescriptionOur rock wool boards have passed third-party laboratory testingKey ApplicationsOur rock wool boards are widely used across industries due to their fire resistance, thermal insulation, and sound absorption properties.1. Construction Industry Exterior Wall Insulation: Reduces building energy loss, meets energy-saving standards (e.g., China's GB 50189, EU's EPBD). Roof & Floor Insulation: Withstands extreme temperatures (-40℃ to 700℃) and prevents heat transfer between floors. Fire Barriers: Installed in stairwells, elevator shafts, and wall partitions to block fire spread (fire resistance duration: 120-180 minutes). 2. Industrial Sector Industrial Equipment: Insulates boilers, furnaces, and heat exchangers to improve energy efficiency and protect workers from high temperatures. HVAC Systems: Wraps air ducts and pipes to reduce thermal loss and noise pollution (sound absorption coefficient: ≥0.7 at 500Hz). Power Plants & Petrochemicals: Resists chemical corrosion and high temperatures, suitable for insulation of pipelines and storage tanks. 3. Transportation Shipbuilding: Used in ship cabins for fireproofing and thermal insulation (complies with IMO SOLAS standards). Railway & Automotive: Insulates train carriages and electric vehicle battery compartments (lightweight, non-toxic).Why Choose Our Rock Wool Boards?Global Certifications: CE (EN 13162), ISO 9001, ASTM C612, and GB/T 11835-2016, ensuring compliance with international markets. Bulk Supply Capacity: 100,000 square meter monthly production, supporting large orders with 7-15 days delivery time. Customization Service: Free sample testing, and personalized size/density/facing options. After-Sales Support: Technical team provides installation guidance, and 2-year quality warranty.
