Internorm, a family-run Austrian company with a legacy of innovation spanning over 90 years, has established itself as a leading name in high-performance window and door systems. Their uPVC windows, in particular, are not just about keeping the weather out; they represent a commitment to cutting-edge technology, exceptional energy efficiency, and a design philosophy that elevates modern architecture.

For British homeowners, architects, and developers seeking a window solution that combines industry-leading thermal performance with sleek, contemporary aesthetics and unrivalled security, Internorm uPVC windows are a compelling choice.

The Internorm Difference: More Than Just uPVC

While many manufacturers produce uPVC windows, Internorm’s approach is fundamentally different. They have consistently pushed the boundaries of what is possible with the material, integrating proprietary technologies and an uncompromising focus on quality.

• I-tec Glazing™: This revolutionary technology involves bonding the glass pane to the window frame with a high-performance adhesive, creating a continuous, permanent bond. This eliminates the need for glazing beads and drastically improves the stability, thermal insulation, and security of the window. The result is a window that is virtually impossible to “lever out,” providing an exceptional level of burglar resistance. The bonding also prevents the frame from warping, ensuring a perfect seal and long-term performance.
• High-Quality Profiles: Internorm’s uPVC profiles are not hollow like traditional frames. They are multi-chambered and often foam-filled, creating a complex internal structure that traps air and provides superior insulation. This meticulous design is crucial to achieving the incredibly low U-values that Internorm windows are known for.
• Exceptional U-values: U-values measure a material’s heat transfer and are a key indicator of energy efficiency. The lower the U-value, the better the insulation. Internorm’s uPVC windows consistently achieve some of the lowest U-values on the market, often well below the standards required by UK Building Regulations. This means a significant reduction in heat loss, lower energy bills, and a more comfortable, stable indoor temperature all year round.

A Range of Styles to Suit Your Home

Internorm understands that one size does not fit all. Their uPVC window range offers a variety of styles and configurations to suit different architectural designs and personal preferences.

KF 410 Internorm uPVC Windows

The KF 410 is a versatile and popular choice, offering a clean, modern aesthetic with excellent performance. Its slim sightlines and concealed fittings give it a minimalist look that is perfect for contemporary new builds and renovations. The KF 410 can be specified with triple glazing and is available in a wide range of colours and finishes, including a wood-grain effect for a more classic feel.

KF 500 Internorm uPVC Windows

For those who demand the ultimate in security and thermal performance, the KF 500 is the flagship uPVC window. It features the innovative I-tec Locking system, which uses integrated flaps in the frame that automatically engage as the window is closed, providing a robust, multi-point locking system that is virtually invisible. This not only enhances security but also contributes to the window’s sleek, uncluttered appearance. The KF 500’s high-tech core ensures it achieves some of the lowest U-values possible for a uPVC window.

KF 200 Internorm uPVC Windows

The KF 200 is a perfect entry point into the world of Internorm, offering a fantastic balance of performance, design, and value. It boasts the same core quality and energy efficiency as the other ranges but with a more simplified profile. It’s a great option for projects where a high-performance, durable, and low-maintenance window is required without the need for some of the more advanced features of the flagship models.

Design and Aesthetics: The Finishing Touches

Beyond the technical specifications, Internorm uPVC windows are designed to be a seamless part of your home’s design.

• Colour and Finish Options: Gone are the days of plain white plastic. Internorm offers a vast palette of colours, from classic shades like Anthracite Grey and Jet Black to a range of textured finishes. You can even choose a dual-colour option, with one colour on the outside to match your external facade and a different one on the inside to complement your interior decor.
• Handle Designs: A small detail that makes a big difference, Internorm’s window handles are available in various styles and finishes, from sleek, minimalist designs to more traditional options, allowing you to personalise your windows down to the last detail.
• Concealed Hardware: Most of Internorm’s uPVC windows feature concealed hinges and fittings, contributing to a clean, uninterrupted sightline and making the windows easier to clean.

Security and Durability: Peace of Mind for Your Home

Internorm’s commitment to security is evident in their innovative technologies. The I-tec Glazing and I-tec Locking systems provide a level of burglar resistance that often exceeds standard industry ratings. The windows are built to withstand forced entry attempts, giving you and your family peace of mind.

Furthermore, uPVC is an incredibly durable material. It is resistant to rot, rust, corrosion, and UV degradation, meaning your Internorm windows will retain their colour and performance for decades with minimal maintenance. A simple wipe-down with a damp cloth is all that is needed to keep them looking their best.
