Market Leading Triple Glazed Windows

At Infinite windows, we work with industry leading manufacturers to bring technologically advanced solutions to our homeowners in Leighton Buzzard. As valued Internorm partners, we supply and install Internorm triple glazed windows that meet and exceed Passivhaus standards. We can install beautiful timber aluminium windows by Internorm with U-values as low as keeping your lovely home comfortable and warm.

Triple glazing uses three strong glass panes with a small pocket of air in between filled with an inert gas like argon or krypton. The expertly engineered design of triple glazed windows makes it nearly impossible to damage and elevates thermal efficiency to the next level. We offer a stunning range of Residence Collection windows and Internorm windows to improve the aesthetics of your property.

To start your dream home improvement project, call us on 01908 785366 or fill out our contact form, and our friendly team member will contact you in no time. With multiple features and customisations, our triple glazed windows will allow you to create stunning visual appeal.

Low Maintenance

At Infinite Windows, we value our Leighton Buzzard’s homeowners’ time by installing low maintenance solutions. Our triple glazed windows are designed with easy case elements and minimal style that can be cleaned with a simple wipe down. These windows are a worthwhile addition to any home with a long life span. Aluminium cladding protects against harsh weather elements, like rain and chilly draught. As aluminium and uPVC do not absorb any moisture, you can enjoy rot and mould free windows for many years.

Customise Your Windows

We value the creative freedom of our Leighton Buzzard homeowners and offer them various customisations with triple glazing to bring their ideas to life. For a traditional appeal, you can choose casement windows, bow & bay windows or tilt & turn windows. If you are looking to achieve a contemporary look our triple glazed aluminium and composite windows by Internorm blend well. 

Each style of window can be further customised to your liking with a beautiful range of RAL colours, wood grain finishes, advanced security hardware, Georgian bars and glazing. At Infinite Windows, we pride ourselves on providing infinite possibilities.

Thermal Efficiency

As energy costs continue to rise in the UK, we offer an energy efficient solution to save money on electricity bills and reduce energy consumption. Our thermally efficient triple glazed windows trap the heat inside naturally and seal off the chilly air. 

We partner with Internorm, the new patron member of Passivhaus Trust in the UK. The Internorm triple glazed windows are designed to meet and exceed Passivhaus standards as they can achieve U-values as low as 0.62 W/(m2K), which is lower than the Passivhaus requirement of U-values 0.8 W/(m2K). 

At Infinite Windows, we want to offer the best solutions that there are in the market to our Leighton Buzzard homeowners.

With advanced technology and hidden locking mechanisms, our Internorm triple glazed windows will improve the security standards of your home

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.
