Choosing new uPVC windows can be a daunting task, so to help you here are some popular FAQs which you might find useful.

  • +
    Can you paint uPVC windows?
    The short answer is yes you can paint uPVC windows. However, it is important to know that new uPVC should not be painted. Windows that have been recently installed should be left for a minimum of 12 months before attempting to coat with paint. uPVC will appear less shiny and hydrophobic after a year, which helps paint bind to the surface.
  • +
    What does uPVC stand for?
    uPVC stands for Unplasticised Poly Vinyl Chloride. Also known as vinyl, it is rigid, durable and long lasting material used in the construction industry. Typically, uPVC is used for making pipes and windows, due to its maintenance free properties.
  • +
    How long do uPVC windows last?
    Typically, you can expect your uPVC windows to last around 20 years. If your windows were installed in the late 1990s (phase 1 uPVC) then it is likely due to efficiency, technology and manufacturing improvements that they could need replacing or at least repairing by now.
  • +
    Can you change handles on uPVC windows?
    Before you upgrade your uPVC window handles with a brand new replacement you need to know what size you need and whether it is a left hand or right hand handle. Make sure you check the size of the handles you are replacing before purchase. The main measurement you need is the spindle length (the piece of metal that sticks out of the back of the window handle to connect directly into the uPVC window).
  • +
    Can shutters be fitted to uPVC windows?
    The process to fit shutters to uPVC windows is the same as that for timber frames. Whilst fixing the shutter frame into place on uPVC simply stop drilling once you feel the screw you are using trying to bite. It is important to think about the handles of the windows whilst fixing shutters into place. Do they protrude into the window recess? You need to ensure that there is no clash between the window handles and louvres of the shutters once opened.
  • +
    Can you change brown uPVC windows to white?
    Painting your brown uPVC windows white is a very cost effective way to change the colour of your windows. However, you will need to use the correct paint and will have the job of maintaining them if you want to keep them looking there best. More recently homeowners are opting for a variety of colours when it comes to windows. Black, Grey Anthracite and Chartwell Green are all becoming vastly popular when it comes to the exterior of the home.

  • +
    Can I fit uPVC windows in a conservation area?
    If you live in a conservation area and find yourself looking to replace your windows, you need to ensure its appearance from the street is in keeping with the area and original character of the building. Timber is the preferred choice in many conservation areas, however you are able to replace them with uPVC counterparts as long as their appearance is not considerably different from the original design. Any changes will need to be approved by the local authority.
  • +
    Do you need to install lintels before having uPVC windows?
    Most windows and doors will have some form of lintel. These are put in place to provide strength at weaker points within a building. Lintel failure within a home can cause serious structural problems. Therefore, it is important that the condition of any existing lintels are checked be a professional before installing new windows.
  • +

    Upgrading your windows to double glazed uPVC units will not only improve the appearance of your home but also provide the additional benefit of added security. Everest Exclusive uPVC casement windows are fitted with GrabLock, which has a minimum of three times the locking surface area of many standard, multi-point or shoot-bolt window locking systems, making it our most secure lock ever.
  • +
    Are uPVC windows double glazed?

A double glazed window is available in a variety of options, with the most popular being a casement.

You will also need to check with your window manufacturer, to establish if drilling into the uPVC windows invalidates your guarantees. You will also have to take into account that the holes once made cannot be repaired.

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 extremely easy to maintain. uPVC is a durable material which 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.

How to clean uPVC window frames

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’s 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.
