Overview of Internorm HS330 Timber Aluminium Lift and Slide Door

Here we have the Internorm HS330 timber-aluminium lift-and-slide door, a premium solution within the Internorm range of windows and doors. This system is a high-quality timber-aluminium lift-and-slide door designed to deliver exceptional performance in both aesthetics and functionality, making it a standout choice for modern homes.

The  Internorm HS330 timber aluminium lift and slide door achieves an impressive U-value of 0.67, placing it among the most thermally efficient lift and slide doors on the market. This level of thermal insulation contributes significantly to overall energy efficiency, helping reduce heating costs while maintaining a comfortable indoor environment year-round. When specified as triple-glazed, the HS 330 timber aluminium lift system delivers even greater high-performance insulation, ensuring your home meets demanding energy standards.

One of the key advantages of this lift-and-slide door is its ability to accommodate large panels. The system can achieve widths of over 3 metres per panel and heights of up to 2.8 metres, creating expansive glazed areas that maximise natural light. With options such as frameless side elements, the HS330 allows for uninterrupted views and a sleek architectural finish, ideal for contemporary designs.

The HS330 operates as a true lift-and-slide door. This means the sash lifts up onto rollers before sliding smoothly across the track. Thanks to this engineering, the system can handle a sash weight well in excess of 300 kilos, yet still glide effortlessly as if it were much lighter. This advanced mechanism ensures ease of use without compromising on strength or durability.

Another important benefit of lift-and-slide doors like the Internorm HS330 is that the sash rests off the rollers for more than 90% of the time when closed. This reduces wear and tear on the rolling components, extending the system’s lifespan and maintaining smooth operation over many years. The track itself is designed to be clean and minimal, providing a flat threshold detail without intrusive grooves, which is perfect for a seamless transition between indoor and outdoor spaces.

In addition to performance and design, security is a key consideration. The HS330 can be specified to meet high security standards such as PAS 24 and Secured by Design, giving homeowners peace of mind that their glazing system is built to resist forced entry while maintaining its elegant appearance.

For customers looking to manage solar gain, Internorm also offers integrated external roller shutters. These can be combined with the HS330 timber aluminium lift-and-slide door to further enhance comfort and energy efficiency. By blocking heat before it reaches the glass, these shutters reduce overheating in warmer months and help lower energy consumption throughout the year.

The system shown here includes external roller shutters connected to a home automation system. At the touch of a button, the shutters can be lowered or adjusted to suit the conditions. The particular shutters on display are light-diverting, meaning they can be angled to reflect sunlight up towards the ceiling, allowing natural light to enter while reducing glare and excess heat.

Although the showroom example features exposed roller shutters, in most projects they can be discreetly concealed behind cladding or render, depending on the building’s design. A further benefit is that all elements can be colour-matched, ensuring the shutters, frame, and overall façade work together seamlessly for a cohesive finish.

While the Internorm HS330 timber aluminium lift and slide door already delivers outstanding thermal insulation and energy efficiency, combining it with external shading solutions further enhances performance. This integrated approach ensures your home remains comfortable, efficient, and cost-effective to run.

Although all this information is available online, experiencing these lift-and-slide doors in person makes a real difference. Visiting the showroom allows you to see the quality, feel the smooth operation, and explore the various configuration options available. It also provides the opportunity to discuss your project in detail, so tailored solutions can be recommended based on your specific requirements.

We would highly recommend coming to see the Internorm HS330 for yourself. By understanding your project, we can help you choose the right combination of high-performance products to achieve the best possible result for your home. We look forward to welcoming you soon.
