Frequently Asked Questions About Sliding Sash Windows
Are uPVC sash windows as good as timber?
Modern uPVC sash windows replicate the look of traditional timber sash windows without the maintenance. They do not need painting, will not rot and offer better thermal insulation. Vitrum Solutions installs EcoSlide sash windows that are virtually indistinguishable from timber.
How much do sliding sash windows cost?
uPVC sliding sash windows typically cost between £500 and £1,200 per window installed. Vitrum Solutions provides free surveys across Buckinghamshire, Berkshire and Surrey with no obligation pricing.
Can you get double glazed sash windows?
Yes. All sash windows installed by Vitrum Solutions are double glazed as standard, with triple glazing available. This dramatically improves energy efficiency and sound insulation compared to original single glazed sash windows.
Do sash windows need planning permission in a conservation area?
If your property is in a conservation area, you may need to match the appearance of existing windows. uPVC sash windows from Vitrum Solutions replicate traditional proportions and profiles, making them suitable for most conservation area applications.

Sliding Sash Windows
If you’re replacing existing sash windows, we can offer a wide choice of styles to match them as closely as possible, and maintain the character of your home.
We can replace bay-style windows including splay and box bay windows. These are a common feature in older properties, and when combined with a sliding sash window their installed appearance is very impressive.
We can also replace arched and swept head windows. These shaped styles are incredibly eye-catching. ECOSlide PVC-U sash windows are
bespoke-manufactured to your exact requirementsto maintain the charm and appeal of your home.
Other design options are available with internal Georgian bar or external astragal bar detailing, to ensure your new windows are as authentic as possible.
Colour & Foil Options
Timber box sash windows were always painted, and you can replicate this look. If you want a more natural effect, our Crystal White, Cream, Golden Oak and Irish Oak foils give a realistic woodgrain appearance that mimics the grained texture and appearance of an original timber window.
We also offer colour outside/white inside options in Chartwell Green, Anthracite Grey, Agate Grey, Rosewood, Black/Brown, Cream, Golden Oak and Irish Oak. With this option, you can choose the external colour you like, while maintaining a white interior to better
suit your home’s decoration.
