Comfort, Quiet & Efficiency — Without Replacing Your Windows
Experience a smarter way to improve your home. Incarnation’s secondary glazing systems are designed to enhance your existing windows — increasing thermal performance, reducing noise and boosting comfort — all without the cost or disruption of full window replacement.

Secondary glazing is an additional pane of glass installed on the inside of your existing window frames. Unlike double or triple-glazing replacements that require removing your current windows, secondary glazing fits seamlessly behind them — preserving heritage features while dramatically improving performance.
Perfect for period homes, listed buildings and properties where traditional window replacement isn’t ideal.
By creating an insulating air pocket between the existing window and the secondary pane, heat loss is significantly reduced. This means:
Cosier rooms throughout the year
Lower heating bills
Reduced draughts and condensation
A practical solution for homes that struggle with heat retention.
Our secondary glazing dramatically cuts external noise — ideal if you live near:
Busy roads
Train lines
Town centres
Schools or airports
Quiet indoors. Peace of mind included.
Secondary glazing respects the charm of traditional windows, especially in:
Period properties
Listed buildings

No need to alter your original frames or lose architectural detail.
