The Core Benefits of Secondary Glazing

The choice to purchase secondary glazing is seldom based upon visual appeal alone. It is a practical upgrade created to resolve a number of common residential and business complaints.

• Acoustic Reduction: Secondary glazing is arguably the most reliable technique for sound cancellation. A considerable space (normally 100mm to 200mm) in between the old and new glass can decrease external sound levels by up to 80% (approx. 50 decibels).
• Condensation Control: By providing a seal that avoids warm, damp indoor air from striking the cold surface of the main window, secondary glazing considerably decreases the threat of condensation and subsequent mold growth.
• Enhanced Security: An additional internal window functions as a secondary physical barrier versus intruders, making it substantially harder to get unauthorized access to the home.

• The Number of Units: Many business use “bulk” discounts for whole-house setups compared to single-window projects.
• Intricacy of Installation: Windows that are out of square, or those situated at substantial heights needing scaffolding, will result in higher labor expenses.
