Cellular Glass Insulation

Cellular glass is a lightweight, rigid insulation material made from recycled glass that has been foamed to create millions of completely sealed glass cells. This unique structure gives cellular glass its exceptional properties: 100% waterproof, non-combustible, extremely durable, and environmentally friendly. With a service life exceeding 50 years, cellular glass provides consistent thermal performance and zero water absorption throughout its entire lifespan, making it ideal for applications where long-term reliability is essential.

Cellular glass offers several unique advantages: it's completely impermeable to water and vapor, making it ideal for moisture-prone environments; non-combustible (A1 fire rating) for enhanced safety; resistant to chemicals and pests; dimensionally stable across temperature extremes (-260°C to +430°C); environmentally sustainable with no harmful emissions; and maintains consistent performance for 50+ years without degradation. These properties make cellular glass the preferred solution for critical applications where failure is not an option, such as below-grade insulation, industrial facilities, and moisture-sensitive environments.

Cellular glass excels in challenging environments where moisture resistance, durability, and long-term performance are critical. Common applications include below-grade insulation (foundations, basements), flat and green roofs, industrial facilities (refineries, chemical plants), cryogenic installations (LNG facilities), high-temperature systems (up to 430°C), food processing facilities, and swimming pools. It's particularly valuable in applications where conventional insulation would degrade due to moisture, chemicals, or extreme temperatures, providing reliable performance where other materials fail.

HUAYUE offers cellular glass in standard board dimensions of 600mm × 450mm, with thicknesses ranging from 40mm to 180mm. We also provide tapered boards for creating drainage slopes on flat roofs. For specialized projects, we can deliver custom dimensions and shapes, including pipe sections for industrial applications. Our manufacturing capabilities allow us to meet specific project requirements, including special edge preparations and pre-cut shapes to simplify installation and reduce on-site waste.

HUAYUE's cellular glass products feature a thermal conductivity value (λ) of 0.038-0.042 W/mK at 10°C, providing excellent insulation performance. Unlike many insulation materials that lose efficiency over time due to moisture absorption or aging, cellular glass maintains its thermal properties throughout its entire service life, even in wet conditions. This consistent performance means that the thermal calculations made during design remain valid for decades, providing reliable energy efficiency and condensation control for the building's lifetime.

Yes, cellular glass is one of the most environmentally sustainable insulation options available. It's manufactured using up to 70% recycled glass, contains no harmful flame retardants or blowing agents, and releases no VOCs or other emissions during its lifetime. With exceptional durability exceeding 50 years, it requires no replacement, reducing lifecycle waste. At end-of-life, cellular glass can be safely disposed of or recycled. Our manufacturing process is optimized for energy efficiency, and our products contribute to LEED, BREEAM, and other green building certification systems.
