Canglong Group’s polyurethane edge-sealed rock wool boards customized for the US market, redefine building envelope standards with an innovative composite structure. Designed specifically for roofing applications in harsh climates, this product achieves synergistic effects of thermal insulation, fire resistance, and moisture resistance through a golden combination of high-density rock wool core and closed-cell polyurethane edge sealing. It provides durable and reliable roofing solutions for industrial plants, commercial facilities, and cold storage buildings in North America.

Key Performance Highlights:

Class A Fire Barrier

The core layer uses hydrophobic rock wool (density ≥120kg/m³), meeting the highest fire resistance certification of ASTM E84 Class A. It is non-combustible when exposed to fire and effectively inhibits the spread of fire, building a solid defense for the safety of personnel and assets.

Superior Thermal Performance

Rock wool fibers form a three-dimensional air gap, combined with seamless polyurethane foam edge sealing, eliminating cold bridging and resulting in a thermal conductivity as low as 0.038 W/(m·K). This significantly reduces building energy consumption and easily meets ASHRAE 90.1 energy efficiency standards.

All-Weather Adaptability

Waterproof and Seepage-Resistant: Polyurethane edge sealing with a closed-cell rate >95% prevents water vapor penetration and resists erosion from heavy rain, snowmelt, and high humidity environments.
Weather Stable: The surface is pre-coated with fluorocarbon resin (PVDF) steel sheet, resisting UV aging and adapting to the extreme temperature differences in the continental United States (-40℃~80℃).

Engineering Value Upgrade

Rapid Installation: Patented interlocking tongue-and-groove design supports nail-free splicing, increasing installation efficiency by 50% compared to traditional roof panels.
Long-Term Maintenance: Anti-microbial corrosion formula prevents mold and insect infestation, ensuring a service life of over 25 years.
Green and compliant: Made from 100% recyclable materials, meeting LEED® and California Title 24 environmental standards.

Canglong Group strictly adheres to both ASTM C612 and GB/T 25975 dual-system production, with each batch of products accompanied by an SGS test report, ensuring full traceability from raw materials to finished products. This batch of roofing panels have already cleared customs at the Port of Los Angeles and will soon be used in the expansion project of a food processing plant in California, helping American customers achieve their sustainable building goals with “Made in China” quality.
