The interlayer of insulating glass is usually filled with inert gas or dry air to improve the glass's heat insulation, sound insulation, and dew prevention performance. Common filling gases include:
1. Air
- The most common and lowest-cost filling medium.
- It has a certain degree of heat insulation and sound insulation effect, but compared with inert gases, it has higher thermal conductivity and poorer heat preservation performance.
2. Argon (Ar) (The most commonly used inert gas)
- Thermal conductivity is about 30% lower than air, effectively reducing heat transfer and improving heat insulation performance.
- Moderately priced, widely used, and often used in LOW-E insulating glass.
- Because argon is an inert gas, it can reduce the oxidation of the inner wall of the glass and prolong its service life.
3. Krypton (Kr) (Advanced heat insulation gas)
- Thermal conductivity is lower than argon, and the heat insulation performance is better.
- Suitable for ultra-energy-efficient glass, especially three-layer insulating glass.
- Higher Price, mainly used in high-end buildings and special glass applications.
4. Xenon (Xe) (Top-level heat insulation gas)
- The strongest heat insulation performance, which can minimize the U-value (heat transfer coefficient).
- Expensive, mostly used in extreme climates or passive ultra-low energy consumption buildings.
5. SF₆ (Sulfur hexafluoride) (Sound insulation gas)
- Mainly used to improve sound insulation, not heat insulation.
- It can effectively reduce external noise and is often used in insulating glass in high-speed railway stations, airports, recording studios, etc.
