Many homeowners mistakenly believe that insulated glass inherently provides sound and heat insulation. In reality, the gas filling the cavity and the glass configuration are the key determining factors.
In a street-facing residence in Shanghai, ordinary insulated glass still allowed clear transmission of traffic noise. After replacing it with argon-filled double silver Low-E insulated glass, noise and heat significantly decreased.
Insulated glass is suitable for street-facing residences, high-rise balconies, and sunrooms, but needs must be clearly defined: For sound insulation, the glass thickness difference and airtightness are crucial; for heat insulation, the Low-E film layer and the width of the cavity are more critical.
