SupplyDouble Glazing (Insulated Glass Unit, IGU)
Double glazing consists of two or more glass panes separated by a spacer bar, forming a hermetically sealed air or gas-filled city (commonly argon or krypton). This structure significantly reduces heat transfer (U-value as low a.4 W/m²·K) and noise transmission (30–40 dB reduction), making it ideal for energy-efficient buildings. Additional features include:
Thermal Insulation: Minimizes heat loss in winter and heat gain in summer, cutting energy costs by ~40%.
Acoustic Performance: Effectively blocks high-frequency urban noise.
Anti-Condensation: The dry air layer prevents interior surface fogging.
Safety & UV Protection: Optional tempered or laminated glass enhances durability, while Low-E coatings reflect 90% of UV rays.
Widely used in windows and facades, double glazing balances functionality with sustainability, though proper installation is critical to oid seal failure.
