What is Insulated Glass?
Insulated Glass Units (IGUs) consist of two or three glass panes separated by spacers to form sealed cavities filled with dry air or inert gases (e.g., argon). The gas layers block heat transfer, significantly improving thermal and acoustic insulation.
Key Components:
| Property | Double Panle (Single Cavity) | Triple Panel ( Double Cavity) |
| Heat Flow Path | Glass→Gas→Glass (1 barrier) | Glass→Gas→Glass→Gas→Glass (2 barriers) |
| U-value | Higher (≈1.8 W/(m²·K)) | Lower (≈1.1 W/(m²·K)) -40% |
| Sound Insulation | Mass Law: 2 panes + gas damping | Mass Law: 3 panes + dual damping + resonance shift |
| Anti-Condensation | ΔT>15℃ | ΔT>25℃ |
| Weight | 5+12A+5: ≈25kg/m² | 5+12A+5+12A+5: ≈38kg/m² |
Summary
| Double Panle (Single Cavity) | Triple Panel ( Double Cavity) | |
| Glass Layer | 2 | 3 |
| Cavities | 1 | 2 |
| Optimal Climate | Temperate | Extreme Cold/Heat |
| Acoustic Weakness | Low-frequency (<250Hz) | Very low-frequency (<125Hz) |
| Enhancement | Low-E + Argon | Dual Low-E + Krypton |
