Our secondary glazing windows are available in the below material...

Why choose secondary glazing?

Whilst many older properties exude a wonderful, historical beauty, Everest understands some of their other traits may not be as desirable.

Our secondary glazing is a perfect solution for cutting out noise, cold and draughts. It traps air between your existing window and the secondary window acting as a form of double glazing to provide insulation and prevent draughts, which ensures your home is so much warmer.

Everest secondary glazing can be even more effective at soundproofing when used in conjunction with our other window ranges. In recent acoustic tests we found that when secondary glazing was fitted in addition to double glazing it reduced the sound by up to 12 decibels (db) - without secondary glazing, the extra 12db would have the effect of doubling the outside noise. We can even add sound absorbing tiles to reduce the noise in your home even further.

Every Everest Secondary Window is tailor-made to fit inside and complement your existing windows, keeping them unobtrusive on the inside and almost invisible from the outside. And they feature anti-burglar catches so your home is even more secure.

If all this wasn’t enough, they’re virtually-maintenance-free as well, and come with a comprehensive 10-year guarantee on materials. So you can rest assured your windows will be well looked after, while you continue to enjoy your beautiful home.

Our secondary glazing is available in a deluxe range as well as the standard range, with concealed hinges, a thicker frame, offset handles, multi-point locking and a tilt function that makes for easier cleaning.

Our secondary glazing windows are...

Warmer

Secondary glazing can help eliminate the draughts and rattling windows that historic and listed buildings can suffer from. Air is trapped between your existing window and the secondary window, which acts as a form of double glazing to provide insulation and ensure your home stays much warmer.

 

Quieter

Quieter

The layer of air between the existing window and secondary window also insulates against outside noises, reducing the amount of outside noises that reach the inside of your home.

More secure

More secure

Secondary glazing will make your home safer and more secure, thanks to anti-burglar catches fitted as standard. The deluxe secondary glazing range also includes a multi-point locking mechanism with a key-lockable handle for enhanced security.

You might also be wondering...

Q: Why might I need secondary glazing?

A: Sometimes homeowners don’t have as much freedom when it comes to upgrading their living space as they would like and energy loss is a very common problem within old buildings. Secondary glazing offers great heat and security benefits within older buildings whilst remaining largely unobtrusive from the outside.  

Q: Is there a choice of glass type?

A: There are more choices than you might think. Obscure glass, decorative glass, security glass, safety glass and anti-sun glass are all viable available to install within your secondary glazing unit, so you have a fair range to choose from.
