Insulation Foam Glass
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.
Technical Specifications
| Category | Key Performance Characteristics |
|---|---|
| Thermal Conductivity | Typically ranges from 0.038 to 0.050 W/(m·K) , providing excellent energy efficiency. |
| Compressive Strength | Very high (usually 400–1,600 kPa), making it load-bearing and suitable for roofing and floors. |
| Water Vapor Permeability | Zero (impermeable) due to its closed-cell structure; it acts as a built-in vapor barrier. |
| Density |
Lightweight, generally between 100–200 kg/m³. |
| Service Temperature |
Operates effectively from -268°C to +480°C (-450°F to +900°F). |
| Chemical Resistance |
Resistant to most acids, alkalis, solvents, and oils; does not degrade over time. |
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.
Frequently Asked Questions (FAQ)
Q1: Is foam glass waterproof?
A: Yes, it is 100% waterproof. Its closed-cell structure prevents water absorption and capillary action, and it acts as its own vapor barrier.
Q2: What are its disadvantages?
A: Higher cost than many alternatives, limited availability in some regions, and brittleness during transport or installation.
Q3: Is foam glass fireproof?
A: Yes, it is non-combustible. It does not burn, support flames, or release toxic smoke, and can withstand temperatures up to ~430°C.
