Available in Single or 2 colour options, with a different colour on the inside and outside of your home.
Our uPVC casement windows are available with either A+15 rated double glazing or industry leading A++21 triple glazing, and include internal low-e glass that reflects heat back into your room, to keep your home warmer and help reduce your energy bills.
A wide range of handles are available to match the style of your home. Our standard handles come in black, gold, silver, chrome or white, whilst the premium 'Monkey Tail' and 'Tear Drop' handle ranges are available in black, gold, graphite and chrome.
Georgian bars are a popular addition and a classic choice for conservation areas. They can either be internal bars between the glass panes for easy cleaning, or external bars on the outside. We believe it's all in the detail so we also add a white gasket to the Georgian bars that blends invisibly into the bar itself.
Our uPVC casement windows have the option of our Smoothweld technology, which gives you an almost invisible corner joint, with clean, seam-free lines, no deep grooves that might harbour dirt and a beautiful, flawless aesthetic.
We offer 2 types of window framing - traditional and contemporary. Traditional makes your frames match on both sides, giving it a symmetrical design, and contemporary allows the glass panes and window openings to vary in size.
It doesn't stop at double or triple glazing - there's also a range of glazing types to suit your needs. Everything from obscure glass, which is perfect for bathrooms and offices, to Decorative Glass with a range of coloured, leaded and bevelled designs.
Our uPVC Windows are A+ rated as standard and made-to-measure to keep your home warmer and help reduce your energy bills. We use a multi-chamber profile, meaning more barriers to prevent heat escaping and low-e internal glass, which reflects heat back into the room. The gap between the panes is filled with Argon gas and the separating spacers are coated in a low conduction material to hold in more heat. Our windows also have double weather-resistant Q-lon seals which keep a weather tight seal to keep out rain and draughts.
Fitted with new GrabLock, our most secure lock ever, you can be reassured your home is offered the highest level of protection. GrabLock has been developed exclusively with leading lock experts, Yale and has three times the locking surface area of a standard window lock. GrabLock has been rigorously tested for strength and security, exceeding PAS24 British Standards and qualifying for Secured by Design the official police security initiative.
Not only do our uPVC windows keep your home warmer and more secure, but replacing standard glazing with Everest uPVC Casement Windows ensures that unwanted noise pollution is kept out - in fact, outside noise can be reduced by as much as 35 decibels when you choose triple glazed windows, which is particularly useful if you live in a noisy area.
We guarantee that our uPVC windows won t rot, rust, peel or flake and we also offer industry leading guarantees on many other aspects of the window for added peace of mind.
They look Smooth and clean and depending on the surrounding materials of the home can actually look quite stunning. We don t believe the windows would be so popular if people did find them cheap and so we re not surprised they continue to be a best seller.
Every single job is different from start to finish, meaning they each have their own challenges and demands. Everest does not operate with a factory-line mentality and so never hurry the installation process. As all of our products are made-to-measure for a perfect fit, the timing of the process is ordinarily the same.
We are proud to say that it really does look like natural Timber, but it comes with all of the modern benefits of a uPVC window, so it is finally possible to get a window that offers traditional looks with the convenience of a modern product.
We recommend you clean your uPVC windows at least twice annually, or more if you live in a coastal or city area. To clean the window frames use warm soapy water, do not use glass cleaners, kitchen or bathroom cleaners on the frames as these can damage them. To remove tough stains use washing up liquid with little or not water and then rinse with water. For tough stains you may have to use a uPVC window cleaner. However, tough the stains never use cleaning agents, caustic or ammonia-based cleaning agents, scouring powder or other abrasive cleaners and steel wool or scouring pads. Washing your uPVC windows twice a year with soapy water should keep your windows looking good and tough stains away.
