Passivhaus Windows
Passivhaus windows are designed to meet rigorous energy efficiency standards, achieving U-values as low as 0.62 W(m/K). These windows prevent heat loss in winter and maintain cool interiors in summer through strategic design. They are ideal for new builds and refurbishments seeking EnerPHit certification.
Triple Glazed Windows
Triple-glazed windows feature 48mm sealed units with three glass panes and argon-filled cavities, delivering exceptional thermal insulation and noise reduction. They maintain indoor comfort while lowering energy bills and preventing condensation through warm-edge spacer bars.
Bifolding Doors
Bifolding doors combine sleek aesthetics with functionality, offering seamless transitions between indoor and outdoor spaces. Available in aluminium or uPVC, they provide thermal efficiency and security while enhancing natural light entry.
Entrance Doors
Custom entrance doors are crafted from premium materials like timber-aluminium composites, offering durability and thermal performance. They enhance security with multi-point locking systems and are available in bespoke designs to match architectural styles.
Timber-Aluminium Windows
Timber-aluminium windows combine the natural insulation of wood with the durability of aluminium. These dual-material frames achieve superior thermal efficiency and require minimal maintenance, making them ideal for modern and traditional properties.

I couldn't recommend Colin and his team at Infinite Windows highly enough. Colin's knowledge of the products and the technical challenges around the fitting of the doors was impressive. The customer attention and care is probably the best i've ever experienced from any business. We were originally going to go for something different but having taken Colin's advice, we couldn't be more pleased with the results. Many thanks to all the team.

Colin and his team fitted a large number of windows, a sliding door, plus a new front door and rear door. The Internorm windows and doors are superb quality and the fitting, and installation went well. Lead times are quite long from Austria - but you would expect this with a great bespoke fitted window and door of this quality - so plan well! Colin and team did an excellent job!

We were looking to change our existing French Doors to sliding doors to increase accessibility to our garden. From our initial interactions the service and support from Infinite Windows and Doors was exceptional. Colin took the time to understand our needs and find the product that was the best match. From initial consultation to delivery and installation, the communication was great, keeping us updated on progress and meeting the delivery dates indicated on order. The installation team was professional and very respectful throughout. We are incredibly happy with the attention to detail and

Very satisfied with the high standard of service provided by Infinite Windows, throughout the whole process from choosing the windows to the final installation. At no time did we feel pressurised to make make a choice and we were given sufficient time and help to decide on the the type and style of windows we wanted. Would highly recommend this company.
