Foam Glass: The Next-Generation Fireproof and Waterproof Insulation Material
Foam Glass: The Next-Generation Fireproof and Waterproof Insulation Material
In modern construction and industrial insulation, Foam Glass is quickly gaining attention as a versatile, eco-friendly solution. Lightweight yet strong, waterproof yet fireproof, this material is making its mark in buildings, pipelines, and industrial facilities worldwide.
What is Foam Glass?
Foam Glass is an innovative insulation material made from recycled glass. Its unique closed-cell structure ensures it is non-combustible, waterproof, and chemically resistant. Unlike traditional insulation, Foam Glass combines high compressive strength with low thermal conductivity, making it an ideal choice for projects that demand both durability and energy efficiency.
How is Foam Glass Made?
- Glass Crushing and Milling: Recycled glass is crushed into fine powder.
- Foaming: A foaming agent is added and the mixture is heated, forming a cellular structure.
- Sintering: The foamed material is fused at high temperatures to create rigid, lightweight boards, pipes, or custom shapes.
This process produces a stable, long-lasting material that performs well under extreme temperatures.
Applications Across Industries
- Construction: Walls, floors, roofs, and façades benefit from its thermal insulation and fireproof properties.
- Industrial Systems: Ideal for cryogenic tanks, chemical storage, and high-temperature pipelines.
- HVAC & Refrigeration: Prevents condensation and reduces energy consumption, keeping systems efficient and durable.
Foam Glass vs Common Insulation Materials
