The best of both worlds

Our uPVC sash windows offer a traditional look and feel combined with modern practicality. They’re low maintenance and so easy to operate as well. And as our tolerance for gaps is so low, there’s none of the sticking or wobbling you get with older windows – or those from certain other suppliers.

Your windows, but much better

Secondary glazing is the perfect choice if you need or want to maintain your existing windows in place but are looking to keep out noise, draughts and the cold. Here, the slightly foggy look you can see is down to the age of the original glass – the glass you essentially can’t see from this picture is our secondary glazing, and it’s even less visible from the outside.

Remember to fit it – then forget it

Now we’ve gone up close, you can see how our secondary glazing actually looks. We tolerate gaps far less than our competitors do, which means your home will be that much quieter, warmer and draught-free. And all the while you can practically forget that the secondary glazing is even there.

Any which way you want

For ventilation that you control, not to mention easy cleaning, these windows are a great option. Both of the windows open to the side, and they can both be tilted as well, which gives you less ventilation but more security.

Just far enough

Here you can see what the windows look like when side opened (main picture) and tilted (top right picture) When tilted, they’re designed not to open too far – a security feature that means you can safely go out even with the windows partially open.

The benefits of installing new windows

A fresh and light living space to help illustrate that investing in the cost of new windows will improve energy efficiency in the home

Retain heat and eliminate draughts with new windows

If the only question on your mind is, how much are new windows, then you need to realise that not all windows are made equally. Our double glazing achieves an A+ rating, with triple glazing rated A++ for even better energy efficiency. Our multi-chamber profile helps prevent heat escaping while the low-e glass reflects heat back inside. Between the panes is filled with Argon gas to stop cold air entering and the spacers are coated in a low conduction material to hold in more heat. We also use double weather-resistant Q-lon seals which keep a weather tight seal to keep out draughts. All this to keep your home warm and to help you save money on energy bills. We're the experts and we know that lower quality new house windows cost families more over time.

Keep your home safe and secure with new replacement windows

Making sure you and your family feel safe in your home is our priority, which is why Everest works constantly to out-think burglars. Our windows are rigorously tested and are so secure they exceed British Standards as well as qualifying for Secured by Design – the official police security initiative. Then there's our most secure lock ever - GrabLock, which has been developed exclusively with lock experts Yale, so you can rest assured your home is offered the highest level of protection.

New double glazing reduces outside noise

New home windows cost you more in the long run if you don't install a quality product. That's why all our windows are bespoke and made-to-measure for a tighter fit. This not only keeps your home warmer and super secure, it also ensures that unwanted noise pollution is kept out, which is particularly useful if you live in a noisy area.

Guaranteed peace of mind when you buy new windows

We offer a range of comprehensive guarantees on our windows including lifetime against fog, condensation and discolouration. Plus, our guarantees are transferrable should you sell your property.

New triple vs. new double glazed windows - what's the best option?

To demonstrate how Everest Triple Glazed Windows compared to standard double glazing, we conducted a thermographic survey to put them to the test.

They've always had a very good reputation and I guess to maintain the reputation, the quality and service has got to be good, which it has been. Mr & Mrs Foster
