UPVC WINDOWS
UPVC windows are one of the most versatile, energy-efficient products on the market, designed to lower energy bills and provide comfort for your home. In combination with double or triple glazing, this innovative material is designed to reduce your energy bills, improve your home’s energy rating and provide extra security. As leading UPVC window suppliers, we are able to offer an extensive range of UPVC windows that allow less energy to escape and keep your home warm, thanks to their low U-value. The lower the U-value, the more energy-efficient the window. Our double glazed UPVC windows offer U-values of 1.4 W/m2K as standard (‘A’ rating), with the option to reduce the overall U-value to 1.2 W/m2K. We also offer triple glazed windows, featuring Soft Coat Xtra and Argon gas, you can further reduce the whole window U-value to only 0.8 W/m2K. Our experts can help you choose the right windows for your property and customise them to meet your specific needs. We also supply a range of UPVC doors to complement your UPVC windows.
CASEMENT WINDOWS
The traditional casement window is the most popular and versatile window design we offer. UPVC casement windows, in particular, provide superb protection against the wind and rain. Hinged either on the side or at the top, casement windows are the most energy-efficient option for most homes. Thanks to our vast range of styles and decorative finishes, we can provide casement windows that will complement any house type. Casement windows are a great choice for period properties, as they help you to retain the original appearance of your home with additional energy efficiency and security benefits. As such, casement windows are ideal for homes across the North East, including listed buildings and properties in conservation areas.


FRENCH WINDOWS
Stylish, secure and versatile French windows, often designed as French doors, add a sense of elegance to any home. With two outward openings and the facility to open either one side or both sides simultaneously, French windows maximise ventilation and can also serve as a fire escape exit, as you can open the full window as you would a door. Thanks to our high window energy ratings and resilient UPVC window frames, we can create French windows and doors that will enhance your home and help you make the most of your space. With a double-glazed window, a sliding mechanism for easy opening, and built-in channels within the profile system that provide a tight seal against the weather, we can offer stunning French windows at a great price.
TILD AND TURN WINDOWS
With their innovative hinge system, tilt and turn windows offer added safety and convenience features to the traditional casement window. Easy to operate, in the ‘Tilt Position’, the top of the window tilts in towards the room to provide enhanced ventilation. In the ‘Turn Position’, the window opens a full 90 degrees inwards, making it suitable as a fire escape exit and offering easy cleaning from the inside of your home. Tilt and turn windows give a contemporary finish and can be made to measure to fit any existing frame. We offer a full range of options to suit any home or room, and can design, install and supply tilt and turn windows quickly and efficiently to homes throughout the North East of the UK. If you’re looking for replacement windows and want a new style, tilt and turn windows can fit into most standard openings, so you won’t need additional building work carried out to replace your old windows with modern tilt and turn frames.


SASH WINDOWS
Sash windows are a traditional style that are opened and closed using a second frame. The most common style is the horizontal sash window, which involves two frames, one of which can be lifted up or down to open or close the window. You can also find vertical sash windows with a sliding sash. Many traditional sash windows were made of wood, but this isn’t very energy efficient and requires regular treatment and care. With our UPVC sash windows, you can create a period look for your home while also improving thermal efficiency and security over traditional wooden windows. Our double glazed windows are low maintenance and can last for 20 years or longer, offering exceptional value for money.
SHAPED WINDOWS
Shaped frames can create a unique look and feel to any new build home or renovation project. Thanks to our advanced moulding and forming technology, we can create double glazed window frames in virtually any shape, from round portholes to gothic arches and unsymmetrical shapes. We’ll then supply glass that’s the perfect fit to create a stunning look for your shaped windows. All shaped frames are designed to complement our window and door range, with a fully sculptured frame finish that can come in white UPVC as standard or be customised. Our coloured UPVC windows, frosted or obscure glass and huge range of fixtures, handles and fittings mean that you can create a custom window that makes your home truly unique.

Double Glazed Windows FAQs
Is It Cheaper To Replace All Windows At Once?
In some cases, it can be cheaper in the long term to replace all windows in your property at the same time, even if the upfront cost is higher. If some of your windows are old and inefficient, then you could improve your home’s energy efficiency and security by replacing all the windows at the same time. If you have to keep replacing individual windows, then you might find that the cost over a year to do each is higher than if you have them all done at once.
How Much Should You Budget For New Windows In The UK?
The price of new windows depends on a range of factors, including the type of windows you choose and the size of your window openings. Generally speaking, you should budget at least £500 per new window, but it might be more if you have larger windows or want a specific style of frame.
Can You Install Windows Yourself In The UK?
While it is legal to install replacement windows yourself, it is not advisable. Replacing windows is a challenging job, and to get improved thermal efficiency from new energy-efficient windows, you need to work with expert window fitters like Window-Tech.
How Long Do UPVC Windows Last?
New UPVC windows can last between 10 and 20 years, depending on the type of windows you choose and how well they are maintained. To ensure that your new windows last as long as possible, ensure that you get them fitted by window installation experts. Window-Tech can design and fit a range of UPVC windows and doors to ensure that they last as long as possible.
