Glass Production Line

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: Glass panes (Float/Tempered/Low-E) Spacers (Aluminum/Stainless Steel/Thermal Break) Desiccant (Molecular Sieve) Sealant (Butyl + Polysulfide)     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
