This system creates a cavity of air in between the two panes, which acts as an effective insulator against both thermal transfer and acoustic waves. Because it is considered a reversible internal alteration, it is the favored option for heritage companies and regional planning authorities.
The Core Benefits of Secondary Glazing

- Acoustic Reduction: Secondary glazing is arguably the most efficient approach for sound cancellation. A considerable gap (typically 100mm to 200mm) between the old and brand-new glass can lower external sound levels by as much as 80% (approx. 50 decibels).
- Condensation Control: By offering a seal that prevents warm, wet indoor air from hitting the cold surface of the main window, secondary glazing substantially decreases the threat of condensation and subsequent mold development.
- Improved Security: An extra internal window functions as a secondary physical barrier against trespassers, making it significantly harder to acquire unauthorized access to the property.
