Aluminium window frames boast many qualities, such as thermal efficiency and durability. When combined with T&K double glazing, the aluminium windows we supply are high performance, long-lasting, and low maintenance. Additionally, we never compromise on security, so all of our windows are installed with our innovative multi-point locking systems as standard.

There is a style for every property in Northampton. From traditional designs and wood effect finishes to modern styles in anthracite grey, they are suited for new builds and period properties alike. Our windows are suitable for commercial and residential use, so they can be installed in offices, hotels, and houses.

If you are a Northampton homeowner and you have been considering upgrading your windows, aluminium is a fantastic option to consider. Aluminium windows are an investment in your home that can end up saving you money in the long term. By reducing your energy usage and the need for expensive upkeep, you will find that the windows pay for themselves!

Our windows are as attractive as they are functional. They are available in many styles and colours, with multiple customisable hardware options, so there is the perfect window solution for everyone. Find out how you can have T&K manufacture and install new aluminium windows in your home.

High Quality Aluminium Windows

We only work with reputable companies that do not compromise on quality. Our aluminium profiles are sourced from AluK, one of the leading manufacturers of aluminium products. This means that our aluminium windows are made from premium quality aluminium that is high performing that will enhance all Northampton properties.

Our double glazing boasts low U-values, meaning they allow optimal light transmission and exceptional heat retention. This improves the thermal efficiency of your property, reducing the need to use central heating regularly. This is particularly helpful for multi-story buildings or larger houses that usually require frequent heating in the winter.

By increasing the insulation of your property with aluminium windows, you could reduce your household carbon emission and may even save on your every bills. Contact us today to find out more about how aluminium windows can make your property more thermally efficient.

Custom Designed Aluminium Window Styles

All of our windows are custom-made and can be customised to suit any property, whether it is a quaint period property in Northampton or a modern commercial building. We have over forty RAL colour and textured woodgrain foil finishes for you to choose from, so there is a finish for everyone. The powder colours do not flake or fade as painted windows do, so you will not have to repaint them!

Our aluminium windows are available as casement windows or tilt & turn windows, so you can choose the design best suited to your property. Aluminium casement windows are excellent for extra ventilation as they allow for large openings, whilst aluminium tilt & turn windows are a secure option that is great for top floor apartments or offices.

Slimmer profiles allow for extra light, which could mean saving money by reducing the need to rely on artificial light sources. View our gallery or book an appointment at your local showroom to get some inspiration for your new aluminium windows.

Happy Customers

I’d firstly like to thank the whole team at T&K. We’re extremely happy with the finished project. Excellent service from start to finish. All tradesmen were polite, professional, tidy and really helpful where needed. Julia and the team in the office were great and helped with any last minute design changes and questions we had. Now we can’t wait to enjoy our beautiful new conservatory. I would highly recommend T&K if you’re looking for a quality professional installation.
