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.
