Leadsun Foam Glass (Cellular Glass) is a high-performance closed-cell insulation material made from pure glass, offering exceptional thermal insulation, waterproofing, fire resistance, and chemical stability. It is suitable for a wide temperature range from -268°C to 482°C and can be used in various environments including outdoor, underground, submerged, and chemically aggressive conditions. Available in boards, blocks, and pre-formed shells for pipes, vessels, and ducts.

• Excellent Thermal Insulation: Low thermal conductivity (0.043 W/m·K at 10°C) ensures efficient energy conservation.
• 100% Waterproof & Vaporproof: Closed-cell structure prevents moisture absorption and vapor transmission.
• Non-Combustible & Fireproof: Class A1 non-combustible material, safe for fire-rated applications.
• Wide Temperature Range: Suitable for cryogenic to high-temperature applications (-268°C to +482°C).
• Chemical Resistance: Resistant to most acids, alkalis, and organic solvents.
• Dimensional Stability: Does not shrink, swell, or deform under thermal cycling or moisture exposure.
• Pest & Mold Resistant: Does not support growth of mold, fungi, or rodents.
• Environmentally Friendly: Made from recycled glass, free from asbestos, CFCs, and fibers.
• Easy to Fabricate & Install: Can be cut, shaped, and installed with standard tools.
