Improve Your Property With Secondary Windows
Secondary glazing is an additional slim, discreet window installed on the inside of your existing window frame. Unlike traditional double glazing, it doesn’t require removing or replacing your current windows, making it the ultimate solution for properties where a full window replacement isn’t an option or costs too much money.
Adding a secondary pane creates an insulating air gap between your original window and the secondary window, significantly improving thermal efficiency, reducing external noise and increasing security.
Where is secondary glazing most useful?
✓ Maintain the original windows of homes in conservation areas or listed buildings while improving energy efficiency.
✓ Properties near busy roads, train lines or airports for a dramatic reduction in noise pollution.
✓ Businesses and commercial buildings can provide more comfort for staff and customers thanks to better insulation.
✓ A cost-effective way to improve energy performance in rental properties without major renovations.
