The benefits of Everest uPVC Windows

Virtually maintenance free Everest uPVC windows on the exterior of a modern home

Virtually maintenance-free

Our uPVC windows are built to last and are extremely easy to maintain. uPVC is a durable material that will never rot, rust, peel or flake and is also lead-free and fully recyclable. They also come fitted with easy clean hinges so they only need an occasional wipe down using warm, soapy water to stay looking great all year round. Find out how to clean uPVC window frames to keep them looking great.

Warmer and quieter

Our uPVC windows are A+ rated as standard and made-to-measure for a perfect fit. The frame and sash have multi-chamber profiles to prevent heat escaping and Low-E internal glass to reflect heat back in. The gap between the panes is filled with Argon gas to ensure cold air stays out and the separating spacers are coated in a low conduction material to hold in more heat. Then there are the double weather-resistant Q-lon seals to keep out rain and draughts. It’s all this that keeps your home warmer, quieter and helps save you money on energy bills.

Strong and Secure

With Everest, you can rest assured you’re getting windows that meet the British Standard for security so your home is offered the highest level of protection. We use internal glazing beads, to prevent the glass from being removed from the outside by would-be intruders. Plus, our casement windows are fitted with GrabLock, developed with lock experts Yale and accredited by the official police initiative Secured by Design. If you opt for a sash window, the traditional style fitch lock is secured into a galvanised steel reinforcement for additional rigidity.

Guaranteed for peace of mind

We offer a range of comprehensive guarantees on our windows including lifetime against fog and condensation between the panes and 20 years on discolouration. Plus, our guarantees are transferrable should you sell your property.

    Can shutters be fitted to uPVC windows?
    Certainly. The process to fit shutters to uPVC windows is the same as that for timber frames as these are normally fitted to the internal fabric of the building rather than directly to the window frames. We'd advise a specialist company to ensure that correct clearances from handles and to hinges to enable easy opening of the windows for ventilation.
