Secondary glazing

Secondary glazing is a great alternative to having new casement windows made, its energy efficient, cost-effective and even allows you to keep your original casement windows, which means its better for the environment too. Secondary glazing is also a popular alternative for listed buildings or properties as it doesn’t affect the external apprentice of your casement windows.

Sound proofing

Noise can be a big problem for old casement windows, especially if you live near railway lines, by busy roads, or next to a prime spot for seagull mating! Again, secondary glazing is perfect for sound proofing, it provides a large cavity space and will create a more effective noise reduction solution than acoustic glass, or double glazing. Here’s some top tips from YouGen on draught proofing sash windows.

How does it work

Secondary glazing involves the installation of new, fully independent secondary window frames that are fitted inside the room of the existing casement window(s).

There are a number secondary glazing options we can offer which include:

  • Lift out secondary glazing – this is the most cost-effective option, and is best suited to rooms or properties where you don’t need to open your casement windows very often
  • Casement-style secondary glazing – this option can be used for both sash and casement windows. It is best suited when full, and regular access is needed to open and close the windows, and there is enough room to accommodate them being full opened.
