HI-FINITY lift-and-slide system




Hi-Finity sliding doors are designed to bring a new level of living comfort to densely populated urban areas. With their thin, barely visible profiles, these doors create the impression of a wall of transparent glass, expanding the boundaries of the room.
Design is key to the development. Even the largest Hi-Finity sliding doors appear elegant, light, and airy, creating a sense of transparency. The interior and exterior spaces seem to merge, creating a boundless view. Despite the system's thin visible profile, it boasts high strength and reliability, ensured by the bond between aluminum and glass. Consequently, the Hi-Finity system allows for the installation of large insulated glass units weighing up to 500 kg.
The system offers various opening options: two- and three-track, center-locking, and combinations of two to six panels. Specially designed rollers and Teflon-coated seals ensure smooth panel movement. Even large systems can be easily opened manually. For added convenience, a concealed drive is installed, opening and closing the doors with the touch of a button.
Large glass surfaces today are associated with low heat transfer, creating a cozy and comfortable environment. The Hi-Finity system, which features single- and double-glazed units, provides superior thermal insulation. Patented, width-adjustable Reynaers profiles are used at the points where the aluminum meets the glass, ensuring a tight fit and excellent seal.
The door locking mechanism is concealed at the top of the door, further protecting it from burglary. The Hi-Finity system, with its triple-glazed unit, is particularly resistant to forced entry, having been tested to RC2 security class. The combination of high sealing with maximum transparency and contemporary design makes this product an excellent solution for modern, energy-efficient architecture.
