Everest uPVC vertical sliding sash windows maintain this authentic appearance of timber, but without the maintenance and are available in woodgrain finishes which look as good as real wood. Our uPVC sash windows are A rated for energy efficiency and include a tilt function for easy cleaning, a perfect combination of performance and practicality.

Everest timber sash windows offer the ideal balance of traditional wooden sash windows combined with the durability, energy efficiency and reliability that comes with buying Everest windows and doors. Precision-crafted for a perfect fit, they also come with a 30 year guarantee to give you peace of mind that they'll last for decades.
Everest's superior double glazing, advanced locking mechanisms and weather resistant seals mean your Everest timber sash windows will keep the warmth in and the cold out, as well as reducing the noise from outside.
These are vertical sliding sash windows made from uPVC. As well as sliding, they tilt for easy cleaning, although uPVC has the advantage of needing little or no maintenance. The frames are also guaranteed for life against fading or discolouration.

Our uPVC sash windows all feature A+15 rated double glazing, a score that our competitors simply cannot match. That way your home doesn't just stay warmer, you also get a nice warm feeling from the much lower energy bills associated with them. Perfect!
One of the beauties of sash windows is the flexibility they deliver, allowing either the top or bottom section to be opened, or both at once. As with all of our timber windows, a beautiful bespoke design like this can be installed within as little as six weeks.

This is a timber sliding sash window in softwood, which comes in a wide variety of colour finishes. We also offer hardwood options, complete with a choice of stained finishes. All of our timber sash windows have a 30-year guarantee against rot and fungus, plus a 10-year guarantee on the whole window and installation.
Here you can see the ring pulls and key-lockable traditional style fitch locks. These are in chrome, but different options are available. Like all of our windows, these are securely beaded to prevent the glass being removed from the outside.
This is a hardwood timber sash window, with a beautiful stained finish. The timber frames naturally retain heat, while the 20mm gaps between the panes of the double glazing keep out the cold and draughts.

Here you can see the wonderful richness of the mellow teak stain, just one of the finishes you can opt for. The main picture shows the decorative horn design in the corners, while the pictures on the right show the durable and effective cords and weights system.
Everest offer sliding sash windows in traditional timber or low maintenance uPVC.
A timber sash window is the most authentic option when replacing wooden windows. Everest timber windows are available in Softwood (European Redwood) or Hardwood (Red Grandis), both responsibly sourced and accredited by the Forestry Stewardship Council (FSC). Expertly handcrafted our wood is laminated and engineered for layers to specially bond together adding strength and rigidity. For even further durability our softwood is finger jointed to eradicate knots and resist twisting.
Engineered wood to stop rattling
FSC certified softwood or hardwood options
Smooth running mechanism - traditional sash cords or modern spiral balance
uPVC sash windows perfectly combine modern technology with traditional styling. Using an innovative spiral balance mechanism, they operate in the same way and maintain the authentic appearance as a wooden sash window. However, uPVC requires little maintenance, no painting and Everest uPVC sash windows include a tilt function which allows both sashes to tilt inwards for easy cleaning. So, uPVC can offer a great alternative, even if it’s just for the rear of a property when the front must be timber.

On the underside of the top sash section there is an optional component known as a horn. There are two types available: plant on horns and through horns. Through horns offer a richer more authentic aesthetic with the bottom section ‘butting’ against the side sections.

Both our timber and uPVC windows are authentic to the traditional sash design, which has been popular for centuries. We have kept with the characteristic deep bottom rail, Georgian bars, central transom and fitch lock. Sliding sash windows can be opened at either the top or bottom for ventilation and to keep your home secure, a restrictor can be engaged to give ventilation without needing to open your window completely. For practicality both sashes on uPVC can be tilted inwards for easy cleaning.
There are two types of opening mechanism available on sliding sash windows. Our uPVC sash windows are fitted with a modern weighted spring design called spiral balance, whilst on timber, you can choose between the authentic cords and weights, designed to balance the weight of the sash or the spiral balance opening mechanism. Both have been precisely engineered to ensure smooth running and easy finger touch opening, making Everest sliding sash windows effortless to open.

We love the authentic looking wood grain effect and we’re so pleased that we chose silver furniture, as we feel it adds a vintage feel to the sash windows at the front of the house. Elaine Firkins
