Insulation Foam Glass is a lightweight, rigid, and closed-cell insulation material made primarily from crushed glass (recycled cullet) and a foaming agent. The raw materials are mixed, placed in molds, and heated in a kiln to approximately 900–1000°C (1650–1830°F). At this temperature, a chemical reaction releases gases (such as carbon dioxide or sulfur dioxide), creating millions of tiny, sealed, independent glass bubbles. Once cooled, the mixture solidifies into a rigid board or block that is 100% inorganic and non-combustible.

Why Choose Our Products?

• Zero Water Absorption – Unlike mineral wool or PIR foam, foam glass does not absorb water or wick moisture. Its impermeability prevents corrosion under insulation (CUI), making it ideal for cryogenic and sub-sea applications.
• Dimensional Stability – It does not shrink, warp, or expand with temperature changes, ensuring a long service life (often exceeding 50–100 years) without settlement.
• Pest and Rot Proof – Being made entirely of glass, it is inedible to rodents, insects, and fungi. It never rots or supports biological growth.
• Environmentally Friendly – Manufactured from up to 60–70% recycled glass, it contains no CFCs, HCFCs, or VOCs. It is fully recyclable at the end of its life.
• Ease of Fabrication – It can be cut, sawn, and drilled with standard woodworking tools, allowing for precise fitting around pipes, vessels, and irregular surfaces.

Primary Applications

• Industrial Sector – Insulation for pipes, tanks, and vessels in petrochemical, LNG (liquefied natural gas), and cryogenic plants (due to its performance at -200°C).
• Building & Construction – Roof insulation, under-floor heating systems, and exterior wall cladding (especially in high-rise buildings requiring fire safety).
• Underground & Below-Grade – Insulation for basements, foundation walls, and green roofs where moisture exposure is constant.
• Special Environments – Cold storage warehouses, data centers, and areas with high chemical exposure or extreme temperature fluctuations.
