Product Description
Product Description
Our rock wool boards have passed third-party laboratory testing
Key Applications
Our 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.
