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.

Double Glazing Reviews T&K


Happy Customers

We were more than happy with all aspects of our conservatory installation, right from Shaun the salesman to the guys on the final visit. All the work went through like clockwork, and we were very happy with the end result. Everyone was so helpful and friendly.
Keith Green
The only time we did not use T&K (it was for two windows and one door) we were so disappointed in the products, we had them taken out and replaced by T&K. All our windows and doors have now been done twice by T&K, and we would never even look at anyone else.
Elizabeth Pridmore
We have used T&K for a new door and complete window installation. From the survey stage, receiving a quotation and final installation, the processes were all straight forward and of course we are more than pleased with the quality of the product and just as important the workmanship and politeness of the fitters. Would not hesitate to recommend T&K to family and friends.
Paul Curtis
My wife and I had windows installed some 15 years ago from T&K and they look as good today as when they were first installed, so much so that we recently had our front, back and two French doors installed. We could not be happier with the results.
Richard Simmons
The T&K team were amazing from start to finish. Professional and punctual from the moment of engagement, quotation, surveying, installation and post-installation service. Extremely friendly and high quality team and our windows and doors were definitely worth the investment. Thanks for your efforts. We wouldn’t hesitate to recommend T&K!
Rachel Phillips
I have used T&K on three separate properties now and they have been great. Cost and product as well as installation as promised. Better still your energy cost nose dive in the winter. Highly recommend!
Philippa Sharp
I am so pleased with our recent installation from T&K that I felt compelled to leave this review. Shaun was respectful and patient in dealing with our request and everything that he promised T&K delivered. We received quotes from four other companies, and I am so happy we chose to go with T&K.
Paul-David Symeou
T&K installed a new door for us the whole service has been outstanding from the visit to the showroom to the day of the installation. All members of the team outstanding could not have asked for more. Highly recommend this company.
Steve Raher
Everyone from the initial sales consultant Steve, to the surveyor, builders, plumbers, electrician, planners and installers were exceptionally professional. I would definitely recommend T&K home improvements to family and friends.
Jonathan Lingard
