The Thermal Break Lift-and-Slide Door is a door system that integrates a thermal-break aluminum structure with specialized lift-and-slide hardware. The door sash is raised or lowered via a control handle, allowing it to then slide horizontally along its track. Through the combined action of aluminum profiles, insulated glazing, lift mechanisms, drainage tracks, and sealing components, this system effectively meets the requirements of architectural projects regarding accessibility, natural lighting, thermal insulation, and expansive panoramic views. It is ideally suited for use in large glass openings, scenic balconies, courtyard passageways, hotel terraces, and commercial spaces.

The 55*76 Thermal Break Lift-Sliding Door features a lift-and-load-bearing roller mechanism, capable of supporting a single sash weight of up to 300kg. This makes it ideal for projects involving large-format glass doors and wide structural openings. Available in dual-track (150mm) and triple-track (225mm) configurations, the system can accommodate various opening ratio requirements. For villas, ocean-view apartments, and hotel terraces, this high load-bearing capacity minimizes the risk of sash sagging during operation.
The door's lifting and lowering mechanism is controlled via a 180° rotating handle: when closed, the sash presses firmly against the frame for a tight seal; when opened, the sash lifts clear of the frame to slide freely, resulting in significantly lighter and smoother pushing and pulling. This structural design is well-suited for large glass doors and high-traffic environments, ensuring a fluid operational experience even with heavier sashes. In hotel suites, commercial clubs, and high-end residential projects, this effortless opening mechanism enhances the overall daily user experience.
This Thermal Break Lift-Sliding Door utilizes PA66GF25 nylon thermal break strips, paired with 5mm+20A+5mm insulated glass units, to effectively minimize heat transfer between the interior and exterior of the door frame. When installed as courtyard, balcony, or terrace doors, the system helps maintain a more stable and consistent indoor temperature environment. The thermal-break structure is particularly well-suited for residential and commercial projects located in regions characterized by cold winters and hot summers.
The Thermal Break Lift-Sliding Door incorporates a concealed, embedded drainage channel structure, featuring a streamlined flow path that allows rainwater to drain smoothly and efficiently away from the track area. For transitional zones connecting indoor and outdoor spaces—such as terraces, courtyards, and balconies—effective drainage is crucial for ensuring a positive long-term user experience. This drainage system is ideally suited for projects in rainy southern regions, coastal residences, and resort properties, effectively preventing water accumulation and backflow issues within the bottom track.
The product features a slim 14mm visible frame profile design which, combined with expansive glass panels, maximizes panoramic views and enhances the sense of openness. The concealed bottom track drainage reservoir creates a clean, minimalist visual aesthetic at floor level. Available in sophisticated finishes—including Grey, Matte Black, and Champagne—the system seamlessly complements both modern residential and commercial interiors. HEKIN offers fully customized project configurations, tailored to specific requirements regarding dimensions, track count, glass specifications, and hardware solutions.
Villa living rooms often require seamless connections to courtyards, swimming pools, or scenic terraces. The 55*76 Thermal Break Lift-and-Slide Door is ideal for large exterior openings; its lift-and-slide mechanism is specifically designed to support heavy glass door panels. When opened, the door panels do not intrude upon interior furniture space, while the expansive glass surfaces enhance natural lighting and visual connectivity with the outdoors—making it a perfect choice for high-end residential developments.
Sea-view apartments demand exceptional performance regarding panoramic views, airtightness, and resistance to wind and rain. This Thermal Break Lift-and-Slide Door is suitable for living room balconies, master bedroom scenic doors, and seaside leisure areas. Its combination of insulated glass and thermal-break aluminum framing effectively minimizes external heat transfer and noise intrusion, while the matte black or gray frame options blend harmoniously with modern, coastal-themed interior designs.
Hotel suites require doors that offer smooth, effortless operation, a quiet user experience, and ease of maintenance for large-scale projects. The 55*76 Thermal Break Lift-and-Slide Door is well-suited for guest room balconies, executive suite scenic doors, and resort hotel terraces. With a single-panel load-bearing capacity of 300kg, it accommodates large glass facades, while the use of CMECH hardware facilitates streamlined management for commercial engineering projects.
Commercial clubs, tea houses, and reception areas require spacious passageways and a high-end aesthetic appeal. This product is ideal for scenic private rooms, lakeside lounge areas, exterior doors for banquet halls, and leisure terraces. The 225mm triple-track configuration allows for wider opening ratios, while the expansive glass surfaces—paired with champagne or matte black frames—serve to elevate the overall sophistication and texture of the space.
Terrace access points require doors that offer robust load-bearing capacity, effective drainage, and convenient passage. The 55*76 Thermal Break Lift-and-Slide Door is perfectly suited for rooftop terraces, garden platforms, poolside walkways, and outdoor leisure zones. Its integrated drainage channel system minimizes rainwater accumulation, while the lift-and-slide mechanism ensures effortless entry and exit—making it an excellent choice for large-scale deployment in both residential and resort developments.
