High-Tech Windows’ uPVC Windows are crafted in a state-of-the-art manufacturing facility, and suitable for any homeowner. Your home will become more energy efficient upon purchasing one of our double glazed windows, due to the vacuum-seal, and will also keep your house safe from unwanted visitors and the differing British weather. We offer a variety of different windows, including sash windows, to add character to your property.


Doors are also a speciality that High-Tech Windows focus on and can be personalised to your exact specifications. Styles include composite doorsresidential doorscomposite doorsFrench or patio doors, all of which come in a variety of shapes. Where possible, the doors will be imbued with the latest double glazing.

Three of the characteristics that High-Tech Windows focus on when it comes to doors are longevity, affordability and aesthetic style, with security of the property taking on a whole other level of importance. Each door, whether it be crafted from uPVC, hardwood, double glazing or composite materials, will provide your home with that extra level of security. Many of the doors on offer have been awarded the Secured by Design accreditation, given by the National Police Chiefs’ Council.


If you’re looking for more space for your home or want to utilise natural light, then one of our conservatories could be the right purchase for you.

For those who want more privacy from a conservatory, we also offer orangeries, which combine brickwork columns with large glass panels that blend into the existing brickwork of your property. You’ll still get the natural light of a conservatory, but with the added solidity and strength of a traditional extension. You can also choose our LivinROOF option.

Single Stories Extensions

The final option in our range of extensions is the simple Single Storey Extension where our team will work directly to meet your home’s needs. An extension will not only compliment the existing character of the property, but also increase its value. All of our extensions are produced in house, meaning there is no supplier. Single storey extensions don’t have a fixed plan, so we can easily work to your specifications.


Through adding a porch to your property, not only will you be adding a new practical space for your home, but you will be adding an extra level of security. Whether you use the space for your shoes or coats, this space will provide a beautiful way for the outside world to enter your home. The double glazing used in the windows also gives your front door a welcoming feel. Like the single-story extension, each porch can be built to your home’s specifications, and the glass can be customised to your own needs.

Secondary Glazing

If you’re looking to update the existing windows of an older property or a heritage home, then secondary glazing is the option for you. The installation will see your windows reinforced, providing not only extra security, but helping you to cut costs on your energy bills. The installation of secondary glazing will keep your home’s beauty and charm.
