Why Choose Everest uPVC sliding sash windows?

Increase energy efficiency and retain the character of your home

Wooden sash windows are beautiful but require years of painting and can experience problems that cause the sashes to stick, making them difficult to open and close. Everest uPVC Sliding Sash windows are low maintenance, they require no painting and with the added benefit of spring balances they are easy to slide up and down. In addition, with highly efficient double glazing they will help to keep your home warmer.

Modern security features on a traditional window

Everest take the extra step to make sure our traditional design provides the most up to date levels of security. We offer two levels of security with both top and bottom sash restrictors so windows can be left open for ventilation whilst restricting access, as well as fitch locks. Fitch locks are traditional sash locks but are key lockable and secured into galvanised steel reinforcement and adhere to the high standards.

Smooth running and easy cleaning

Everest uPVC sliding sash windows are fitted with spring balances, this assists the lifting and closing of the sash window so the window can be opened and closed with minimum effort. We then use advanced brush seals on the running surfaces to facilitate easy opening. In addition, Everest sash windows offer a tilt-in-hinge design which makes cleaning the outside of the window from the inside very simple, saving on window cleaning costs and an ideal solution for top-floor windows.



Modern spiral balance

A spiral balance system sits within the frame and uses a series of springs to counter balance the sash to ensure a smooth opening mechanism. This spiral balance system replaces the cords and weights system used in traditional sliding sash windows, giving a slimmer window profile resulting in more sunlight and warmth. Traditional sash windows are likely to be fitted as 'box sashes' and replacing these traditional sashes for uPVC is a specialist task which must be performed by a qualified installer. Everest installers are trained to the highest standards and ensure that our uPVC sash windows stand the test of time.

Internal glazing bead on an Everest uPVC sash window

Secure internal glazing bead

All Everest uPVC windows are fitted with an internal glazing bead for two reasons. Firstly, it ensures the window is much more secure than if the glazing bead was put on the outside. The glazing holds the glass in place and if it is inside your house then it prevents potential unwanted visitors from removing the beading and glass and gaining access to the property. Secondly, it means that glazing can be fitted from inside the property, removing the need for glass to be carried up ladders or onto scaffolding and making installation a much safer process.

Commonly Asked Questions

  • +
    Can you have double glazed sash windows?
    Double glazed sash windows are an ideal choice for conservation areas or for those who wish to maintain the look and feel of a period property. You can opt for an authentic timber sash look or a maintenance free uPVC option available in woodgrain finishes.
  • +
    Can I replace my sash windows with casement windows?
    Before you look to replace sash windows with casement windows it is important you check with your local authority. In some instances, for example if you live in a conservation area or a listed building, it may not be possible to place your sash windows with a modern casement window design or you may need to apply for planning permission. You will also need to consider your local area, to ensure that any change you make is in keeping with your neighbours. Additionally, it is worth considering if replacing your sash windows with casement windows would make the property less desirable for future owners.

    How long do uPVC windows last?

    You should expect uPVC windows to last a minimum of 20 years, but with maintenance and varying factors, some windows can have a much longer life than expected.

    Window typeHow long they lastEverest guarantee
    Double glazed units25 yearsLifetime for condensation and fog
    uPVC windows20-25 yearsLifetime for discolouration (white uPVC)
    Aluminium windows45 years25 years for the profile
    Hardwood timber windows50 years30 years against rot of the profile

    The quality of window frame products varies dramatically between manufacturers and installers. Cheap uPVC will warp and discolour long before a quality uPVC frame would. If frames are not fitted properly, they can be prone to water ingress, damp and draughts that will speed up deterioration.

    Can I fit uPVC windows in a conservation area?

    If you live in a conservation area, you need to check with your local planning office about limitations for window replacement. There may be a note in your Deeds about any restrictions.


    Usually, in a conservation area, any changes to the fabric of the building have to be made like-for-like. And that will include materials.


    If you currently have timber sash windows, you have to replace with timber sash windows.


    Not all local planning offices follow the same rule, so always check to find out what you can and can't do.

    How much do uPVC windows cost?

    A white uPVC casement window is the most economical option, costing between £600 to £1,800 depending on size, glazing design and how many are being replaced in the property. However, these are average guide price ranges and not a definitive cost to replace windows in your home.
