• Acoustic Reduction: Secondary glazing is probably the most reliable approach for noise cancellation. A significant space (typically 100mm to 200mm) in between the old and new glass can reduce external noise levels by as much as 80% (approx. 50 decibels).
• Condensation Control: By supplying a seal that avoids warm, wet indoor air from hitting the cold surface area of the primary window, secondary glazing significantly lowers the risk of condensation and subsequent mold development.
• Enhanced Security: An extra internal window acts as a secondary physical barrier versus intruders, making it significantly harder to gain unauthorized access to the residential or commercial property.
