Key Features
Exceptional Thermal Performance
Despite its impressive size—accommodating glass panels up to 3.2 m in height and up to 400 kg per sash—the HS 330 operates effortlessly thanks to its advanced lift-slide mechanism. With a light push, even oversized panels glide smoothly along the track, opening up living spaces to natural light and panoramic views. The aluminum exterior requires virtually no maintenance, while the timber interior can be finished to suit any aesthetic. This combination ensures long-lasting durability, energy efficiency with U-values as low as 0.73 W/m²K, and minimal upkeep for years to come.
Superior Noise Insulation
The Internorm HS 330 timber-aluminum lift-slide door provides outstanding sound protection, achieving acoustic insulation values of up to 40 dB depending on glazing selection. This means disruptive outside noise—such as traffic or city sounds—can be reduced by up to 90%, creating a calmer, more comfortable indoor environment. The combination of a high-performance sealing system, triple glazing options, and precision craftsmanship ensures that even with expansive glass surfaces, your home remains quiet and peaceful.
Enhanced Security
Built with reinforced timber-aluminum construction, the HS 330 is designed to meet the highest European security standards. Featuring multi-point locking and the option to upgrade to RC2 or RC3 resistance classes, the door offers certified protection against forced entry. The robust aluminum exterior resists impact and weathering, while the solid timber core adds structural strength, giving homeowners reliable safety without compromising on design or large glazed openings.
