Customise Your Windows

Our triple glazed windows come in various styles: sliding sash windows, casement windows, aluminium windows, bow and bay windows, tilt and turn windows and Internorm windows.

Internorm windows consist of three materials, uPVC, timber aluminium and uPVC aluminium, all designed to keep your home safe and secure throughout the year.

With these options, your triple glazed windows are fully customisable. We provide a selection of RAL colours, including dual colouring for exterior and interior configurations. We offer woodgrain finishes for a modern appearance of timber without the hard setbacks of older wood.

Additionally, our decorative hardware options like Georgian bars and ironmongery ensure that your new triple glazed windows offer the bespoke look you need to blend in with your current Northampton architecture.

Thermal Efficiency

One of the main features of our triple glazed windows is their stunning thermal efficiency. Double glazing will become a thing of the past; triple glazing surpasses expectations for a comfortable interior temperature all year round.

Due to this incredibly innovative, unique design choice, the triple glazed panels are separated by small gaps to ensure that the natural warm air doesn’t escape. These windows have been engineered to trap and retain this heat, reflecting it into your home – giving you the perfect indoor temperature.

Become less reliant on your central heating so that Northampton homeowners can enjoy all the warm comfort without the costs of your energy bills rising. Save money with our triple glazed windows, and make a practical, long term investment today!

What Do Our Customers Say?

Excellent and prompt service from Infinite Windows & Doors when we opted to use them to provide our bifold doors. The builder who is building our extension failed to sort them through his “usual” window company so we cast out on our own and found Infinite. I’m very glad we did. The doors arrived earlier than expected, and were fitted in the course of an afternoon. They look fabulous and will look even better when the rest of the extension build is completed!

S. Thomas

Amazing knowledge from the salesperson, great clarity of documentation, customer service, installation and quality of products. Highly recommend. So refreshing to deal with a professional, approachable Company who practice integrity.

W. Rust

From start to finish we have been impressed by the professionalism and enthusiasm of the team at Infinite Windows & Doors Ltd. Their price was competitive. They worked quickly, neatly and efficiently and the standard of finish was excellent. Everyone was polite and friendly and we can highly recommend them.

E. Chua

Colin, Jamie and Jackie are a great team and a joy to work with. I introduce all my clients to them, knowing they will receive one to one attention throughout the whole process. They know their products inside out from pricing, technically to fitting on site. They work with the Architect throughout the process, providing CAD details. They work to ensure that the process is as simple and efficient as possible.

Excellent company all round. The service we received from Colin and Jacky was 2nd to none from start to finish. They have a super showroom in Milton Keynes and they displayed such a genuine interest in our project accompanied too, by their ample product knowledge which helped assist with our designs

We can thoroughly recommend them.
