Secondary Glazing is a term you might have heard of when looking in to double glazing products, however what exactly is secondary glazing and how does it differ from double glazing?

Essentially Secondary Glazing is where a discreet, internal window is fitted to an existing window to enhance performance. Usually windows with secondary glazing fitted to them would be single glazed, however its perfectly possible to add secondary glazing to a double-glazed window also.

Now you might be thinking why not replace the existing windows which are not performing with some High-Performance A-Rated PVC-U Windows?

Sometimes that is simply not possible due to the building been listed, or residing in a conservation area. This is where secondary glazing comes in, you are able to install it in both Grade 1 and 2 listed buildings, along with buildings that reside in conservation areas. Allowing for the traditional windows to remain, yet for the building to still have high performance, energy efficient windows.

Something to keep in mind is that the installation of secondary glazing within conservation areas is advised by Historic England as the installation does not change the original character of the building.

The key benefits of secondary glazing are:

  • Reduction of noise levels by up to 80%
  • Reduction of heat loss by up to 65%
  • 10% more heat efficient than double glazing

In addition, secondary glazing from Gardinia is available in over 200 RAL colours and can be installed in arched frames.

With that in mind I think you will agree secondary glazing is a great option for properties that are required to maintain a traditional look, however still desire modern, energy efficient thermal performance to ensure the home is both greener and warmer.
