Why choose Everest uPVC windows?

Our uPVC windows reflect the latest advances in window technology. Their superior quality is a signature of Everest products and with Everest uPVC Windows, you can enjoy the following benefits and options:

Unique to Everest

  • A+15 rated double glazing windows - the leading score among competitors, saving up to £450 a year on energy bills and keeping you warm
  • A++ rated triple glazing windows - so good that they changed the grading system, our warmest ever windows are 35% more effective than double glazing
  • Brighter white uPVC window frames, guaranteed not to discolour or fade for life
  • Optimum performance - 20mm gaps between window panes on double glazing, 12mm gaps on triple, ensuring the cold air stays out
  • Extra secure - New GrabLock, developed with Yale, has three times the locking surface area of a standard, multi-point window lock making it our most secure lock ever. Plus our windows have internal glazing beads for improved security, exceeding British Standards.
  • Made to measure for a perfect fit – unlike other suppliers, we have a much smaller tolerance for gaps and use a uPVC trim around the edge of the windows for a neater finish
  • New Smoothweld technology making the joints of your frames almost invisible
  • Installation speed – we install quality bespoke windows within 4-weeks of purchase
  • Guaranteed for life on double and triple glazing against fog or condensation between the panes of the sealed units of our casement and tilt turn options, with a further 10-year guarantee on materials and workmanship, as standard

And still there's more...

  • Up to 16 chambers (9 in window frame and 7 in sash) making your home warmer and more secure
  • Low E internal glass to reflect heat back into the room and minimise energy loss
  • Q-Lon seals improve weather resistance as the seals have no memory and therefore always return to their natural position
  • Low iron outer glass pane to improve window clarity
  • Traditional framing options giving you a choice of equal sightlines for a balanced look
  • Built to lastand easy to maintain - manufactured to the highest quality, so they won’t rot, rust, peel or flake, with an occasional wipe down using warm, soapy water keeping them at their best all year round
  • Easy clean hinges offering an optional extra to keep your uPVC frames looking great
  • Lead free and fully recyclable material, in-keeping with our “green living” ethos
  • Wide range of colours both single and two-colour options, allowing you to have a different colour on the inside and outside of your home
  • Ideal for traditional or conservation properties as the same style can be retained, if needed

FAQs

Q: Will the finish on uPVC windows degrade over time?

A: We guarantee that uPVC won’t rot, rust, peel or flake and also offer industry leading guarantees on many other aspects of the window for added peace of mind.

Q: Do uPVC windows look cheap?

A: 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.

Q: Is the supply and installation of uPVC windows quicker due to their popularity?

A: 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.

Q: How convincing is wood effect finish on uPVC?

A: 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.
