The 40*65 Medium Slim Sliding Door features a 3.0mm profile wall thickness, offering superior load-bearing capacity compared to standard interior sliding door configurations. The 65mm visible sash width strikes a perfect balance between visual lightness and structural support, making it ideal for taller door openings and wider spans. Available in 105mm double-track and 161mm triple-track configurations, it accommodates a wide range of spatial widths and is well-suited for bulk procurement in residential, hospitality, and commercial projects.
The Medium-Narrow Sliding Door utilizes a 5mm + 20A + 5mm insulated glass configuration. The expansive glass surface area enhances natural indoor lighting and creates a heightened sense of spatial openness. The medium-narrow frame minimizes visual intrusion, maintaining clear sightlines between living rooms, balconies, bedrooms, and leisure areas. For residences with scenic views or seaside apartments, this configuration accentuates the panoramic outlook while making the interior feel more spacious and luminous.
The 40*65 Medium Slim Sliding Door operates via a sliding mechanism, allowing the door sash to glide along its track without encroaching upon the interior floor space required for door swing clearance. Integrated with CIVO brand locking mechanisms and track systems, it is engineered to withstand the demands of frequent daily opening and closing. For high-traffic zones—such as living rooms, kitchens, balconies, and hotel suites—the smooth sliding experience enhances user convenience and simplifies long-term maintenance and management.
Compared to ultra-narrow-frame doors, the Medium-Narrow Sliding Door places greater emphasis on balanced proportions and a sense of structural solidity, making it particularly suitable for large-format glass openings. The combination of a 3.0mm profile thickness and a 65mm visible sash width ensures the door maintains a harmonious visual presence, even when installed across expansive areas. For luxury villas, commercial clubs, showrooms, and large-format apartments, this medium-narrow design avoids the visual heaviness of overly thick frames while simultaneously eliminating the flimsy appearance often associated with excessively thin frames.
Available in a palette of colors—including Grey, Champagne (Electrophoretic Finish), "Skin-Touch" Black, and Brown—the system can be seamlessly integrated into a wide variety of interior design styles. Both double-track and triple-track configurations can be selected based on specific requirements regarding opening widths, opening ratios, and spatial circulation patterns. HEKIN offers comprehensive customization services—adjusting dimensions, colors, glass specifications, and hardware solutions according to project-specific needs—to assist procurement professionals in sourcing complete door and window packages for high-end residential fit-outs, commercial spaces, and hospitality projects.

The transition between the living room and the balcony requires a balance of natural lighting, ease of passage, and spatial separation. The 40*65 Medium Slim Sliding Door is ideal for connecting living rooms to scenic balconies in spacious apartments and residential homes. Its sliding mechanism ensures that no floor space is encroached upon—leaving ample room around sofas, coffee tables, or cabinetry—while the 5mm+20A+5mm insulated glass configuration enhances indoor illumination and maintains an overall sense of spatial openness.
Sea-view apartments often require expansive glass facades to showcase the exterior scenery. This Medium-Narrow Sliding Door is perfectly suited for seaside balconies, panoramic living rooms, and bedroom entryways leading outdoors. The 65mm sash profile minimizes frame obstruction to maximize the view, while the robust 3.0mm profile wall thickness makes it suitable for larger door openings. Available in finishes such as Gray or "Skin Black," its aesthetic blends seamlessly with the style of modern, sea-facing residences.
Hotel suites demand high standards regarding spatial aesthetics, operational reliability, and ease of maintenance. The 40*65 Medium Slim Sliding Door is an excellent choice for connecting bedrooms to balconies, reception areas to scenic zones, or for delineating leisure areas within a suite. The insulated glass configuration helps enhance indoor comfort, while CIVO brand hardware and the smooth-sliding mechanism ensure ease of daily use for guests, as well as streamlined management for hotel staff.
Commercial clubs, tea houses, and reception areas require door systems that serve both as visual showcases and functional spatial dividers. This product is suitable for use in scenic private rooms, meeting rooms, lounge areas, and window-facing spaces. The combination of a medium-narrow frame and large glass panels minimizes any sense of spatial confinement, creating a seamless visual flow between the interior and exterior environments. Colors such as Brown and "Champagne Gold" (via electrophoretic coating) complement high-end commercial interior design styles.
Exhibition halls require clear circulation pathways and a clean, minimalist visual aesthetic. The 40*65 Medium Slim Sliding Door is well-suited for delineating product display zones, meeting and negotiation areas, and various functional sections within an exhibition space. Available in dual-track (105mm) and triple-track (161mm) configurations, it offers flexibility to suit various door opening dimensions, while the sliding mechanism is ideal for high-traffic environments. The door's sleek, minimalist lines ensure minimal visual distraction, allowing the focus to remain squarely on the displayed exhibits.
