Secondary glazing adds a discreet, slim internal window behind your existing glazing, dramatically improving thermal performance and noise reduction without replacing your original windows. It is the ideal solution for listed buildings, conservation areas, and any property where the original windows must be retained.
Key Features
No Replacement Required
Your existing windows stay exactly as they are. Secondary glazing fits discreetly behind them on the inside of the reveal.
Listed Building Friendly
Because the original windows are untouched, secondary glazing is almost always acceptable in listed buildings and conservation areas where replacement is not permitted.
Exceptional Noise Reduction
The air gap between original and secondary glazing provides outstanding sound insulation, reducing external noise by up to 80%. Ideal for properties near busy roads, railways, or flight paths.
Improved Thermal Performance
Secondary glazing significantly reduces heat loss through windows, improving comfort and cutting energy bills without altering the external appearance of your property.
Condensation Reduction
The additional barrier reduces condensation on original windows, helping protect timber frames from moisture damage.
Security Enhancement
An additional layer of glazing with its own locking system provides improved security for ground floor and accessible windows.
