Why Choose Secondary Glazing?
The primary appeal of secondary glazing lies in its adaptability. Unlike double glazing, which requires the elimination of the original window, secondary glazing sits inside the property. This makes it a perfect option for preserving the aesthetic stability of architectural heritage.
1. Thermal Insulation and Energy Efficiency
Heat loss through single-pane windows can account for approximately 25% of a home's overall energy waste. By including a second layer of glass, an insulating pocket of air is developed. This “thermal buffer” lowers drafts and assists preserve a constant internal temperature level, resulting in lower energy expenses and a lowered carbon footprint.
2. Superior Acoustic Performance
While double glazing is exceptional for thermal retention, secondary glazing is frequently exceptional for soundproofing. In a double-glazed system, the 2 panes of glass are spaced very closely together (generally 16mm to 20mm). Secondary glazing permits a broader space (normally 100mm to 200mm), which functions as a more effective barrier versus low-frequency traffic sound and city disruptions.

- Hinged Units: These open like a basic door or window. They are ideal for windows where full access is needed for cleansing or where the initial window has a special shape.
- Lift-Out Units: These are utilized for windows that are seldom opened. The entire panel can be raised out of the frame for seasonal cleansing.
Repaired Units: A permanent 2nd pane remains in location. This is the most basic and most economical version, though it limits access to the primary window.
