folding sliding glass doors

Product Details

The DERCHI 54 Invisible Ghost Sliding Door is an aluminum sliding door system engineered for interior applications where visual continuity and spatial openness are priorities. Its defining characteristic is the moving-track mechanism: rather than remaining stationary while the panel slides, the track itself travels with the door, allowing the panel to align flush with the wall opening and effectively vanish from view. This creates an effect distinct from standard sliding doors or bi-fold systems, where frames, tracks, and hardware remain visible even when the door is fully open.

Construction-wise, the system employs concealed tracks above and flush floor rails below, eliminating the visual clutter of traditional hanging mechanisms. The floor rails integrate level with the finished floor surface, removing trip hazards and enabling smooth transitions between rooms—a feature particularly valuable in residential settings with children or elderly occupants. The door material uses 2.0mm thick aluminum with a frame-wrapping structure for rigidity, while the profile thickness is listed at 1.4mm. Buyers should confirm with DERCHI which measurement applies to which component, as the source data references both figures without clarifying the distinction.

Performance credentials are well-documented: wind pressure resistance reaches 5000 Pa, water tightness holds to 700 Pa, air infiltration stays around 1.2 m³/(m·h), sound reduction hits approximately 35 dB, and thermal insulation delivers a U-value near 2.0 W/(m²·K). However, the glass configuration responsible for these thermal and acoustic results requires buyer verification—the specification table lists 8mm single tempered glass, while performance descriptions reference insulated and multi-layer glass. These may represent different available configurations, and buyers should confirm which glass type corresponds to which performance level before ordering.

Hardware is sourced from European suppliers, with each roller supporting up to 80KG. The bidirectional buffer technology slows the door before it reaches the fully open or closed position, preventing finger pinch injuries. A narrow aluminum handle with magnetic lock point keeps the aesthetic consistent with the frameless design philosophy. Opening direction can be inward or outward, providing flexibility for different floor plans and installation conditions.

Product Features

• Invisible Opening Effect: The signature feature of this door system is the moving-track mechanism that allows the door panel to align perfectly with the wall opening, creating a visual effect where the door seems to disappear. Unlike standard sliding doors where the track remains visible and the panel sits offset from the wall plane, this system conceals the operational hardware entirely. For B2B buyers specifying doors for high-end residential or hospitality projects, this invisible effect delivers a distinctive aesthetic that differentiates the space. Buyers should confirm the exact wall cavity requirements and structural conditions needed to achieve the full invisible effect, as installation conditions may vary by project.

• Concealed Tracks & Frameless Construction: By eliminating traditional hanging elements and exposed tracks, the system achieves an ultra-clean appearance that enhances the sense of openness in any room. The frameless construction means no visible vertical stiles or rails interrupt the glass surface, maximizing natural light transmission and visual continuity. This is particularly valuable in compact spaces such as bathrooms, kitchens, and closets where visual clutter can make the room feel smaller. Procurement teams should verify that the concealed track installation requirements are compatible with their project's ceiling or header structures before specifying this product.

• Flush Floor Rails: The floor rails are designed to sit level with the finished flooring, eliminating trip hazards and creating a smooth transition between spaces separated by the door. This trip-free design is a meaningful safety feature in homes with young children, elderly residents, or individuals with mobility challenges, and it also simplifies cleaning by removing the channel or lip that conventional sliding door tracks create. Buyers should coordinate with their flooring contractors to ensure the floor rail integration is planned during the sub-floor preparation stage, as retrofitting flush rails into existing flooring may require additional work.

• Bidirectional Buffer Technology: The door incorporates buffer technology that slows the panel as it approaches the fully open and fully closed positions, significantly reducing the risk of finger injuries. This safety mechanism operates in both directions, protecting users whether they are opening or closing the door. For projects subject to safety regulations or accessibility standards, this feature provides an added layer of protection beyond what standard sliding doors offer. Buyers should confirm the buffer force settings and whether they can be adjusted to meet specific project safety requirements or accessibility compliance standards.

• Thermal Break Design: The aluminum profile incorporates a thermal break that interrupts the conductive path through the frame, reducing heat transfer between interior and exterior environments. Combined with insulated glass options, this design achieves a U-value around 2.0 W/(m²·K), contributing to stable indoor temperatures and reduced energy costs over the building's operational life. Buyers evaluating this door for projects with energy code compliance requirements should confirm which glass configuration delivers the stated U-value, as the relationship between the listed 8mm single glass and the thermal performance figures requires clarification with the manufacturer.

• High Wind Pressure & Water Resistance: With wind pressure resistance rated at 5000 Pa and water tightness at 700 Pa, this door system is built to withstand demanding environmental conditions. The 5000 Pa wind rating makes it suitable for high-rise installations and coastal properties where wind loads are a significant design consideration, while the 700 Pa water tightness provides reliable rain resistance. Buyers specifying doors for exposed or elevated locations should verify that these performance values apply to their specific panel size and glass configuration, as performance can vary with door dimensions and glazing type.

• Sound Insulation Performance: The system achieves approximately 35 dB of sound reduction through multi-layer glass and quality gaskets, which is sufficient to reduce typical street traffic noise to a faint background level. This acoustic performance makes the door appropriate for interior partitions in environments where noise control matters, such as hotel guest room dividers, home office enclosures, or conference room partitions. Buyers should confirm which glass configuration delivers the 35 dB rating, as the specification references both single and multi-layer glass options, and acoustic performance will differ significantly between them.

• European Hardware System: The hardware package features European-sourced components with an 80KG load capacity per roller, ensuring smooth and reliable operation even with larger or heavier panel sizes. European hardware is widely recognized in the architectural door industry for precision engineering and long-term durability, which reduces maintenance calls and replacement costs over the product lifecycle. Buyers should confirm the specific hardware brand and the availability of spare parts in their target market, as long-term serviceability is a key consideration for commercial and hospitality projects.

Customizable Styles

• Glass Options: The standard configuration lists 8mm single tempered glass, while performance descriptions reference insulated and multi-layer glass that contributes to the stated U-value and sound reduction ratings. This suggests multiple glass configurations may be available to suit different performance requirements. Single tempered glass may suffice for interior partitions where thermal insulation is less critical, while insulated or laminated configurations would be appropriate for exterior-facing installations or acoustically sensitive applications. Buyers should confirm available glass types—including double glazing, laminated glass, and low-E options—and verify which configuration corresponds to the published performance data before finalizing their specification.

• Frame & Material Options: The door is constructed from aluminum with a frame-wrapping structure, using 2.0mm thick door material and 1.4mm profile thickness. Aluminum provides the strength-to-weight ratio needed for the frameless design while resisting corrosion in humid environments such as bathrooms and coastal properties. Buyers should confirm with DERCHI whether alternative frame depths or material thicknesses are available for projects with specific structural or performance requirements, and clarify the distinction between the 1.4mm profile thickness and 2.0mm door material thickness to ensure specifications align with project needs.

• Size Options: The opening panel dimensions range from 350mm to 850mm in width and 400mm to 2400mm in height, with total opening widths accommodating spaces up to 1200mm. This size range covers typical interior door openings for bathrooms, kitchens, and closets, though larger openings may require multi-panel configurations. Buyers should confirm whether the 1200mm maximum space width refers to a single-panel or multi-panel setup, as the single panel width maximum is 850mm. Custom sizes within the stated ranges can be discussed with the manufacturer to match specific project openings.

• Color / Finish Options: Specific color and surface finish options are not detailed in the current product data. Aluminum door frames are commonly available in anodized finishes, powder-coated colors, and wood-grain transfers, though buyers should confirm the exact finish range available for the 54 Invisible model with DERCHI. The finish selection affects both aesthetics and durability—powder coating provides excellent color retention and scratch resistance, while anodizing offers a metallic appearance with superior UV stability. Buyers should request color samples or a finish chart to coordinate with their interior design scheme.

• Opening Configuration: The door can open either inward or outward, providing flexibility for different room layouts and furniture arrangements. The choice of opening direction affects which side of the frame receives the magnetic lock and how the door stacks when fully open. For spaces with limited clearance on one side, selecting the appropriate opening direction is essential to avoid conflicts with cabinetry, fixtures, or traffic flow. Buyers should specify their preferred opening direction at the time of order and confirm that the track and buffer configuration will support their chosen orientation.

• Project Customization: DERCHI's manufacturing scale—with a 70,000 m² factory and over 100 national patents—supports a range of project-specific customizations. Buyers undertaking large-scale residential, hospitality, or commercial projects may discuss custom panel sizes, specialized glass configurations, hardware upgrades, or finish requirements directly with the DERCHI team. Customization capabilities and lead times should be confirmed early in the project planning process, as bespoke configurations typically require additional production time and may affect minimum order quantities.

Hardware Accessories

• Handle: The door is equipped with a narrow aluminum handle designed to maintain the frameless aesthetic of the system. The slim profile integrates with the door edge rather than protruding into the room, preserving the clean lines that distinguish this product from conventional sliding doors. A magnetic lock point secures the door in the closed position, providing reliable latching without the visual bulk of a traditional lock mechanism. Buyers should confirm the handle finish options available to coordinate with other room hardware, and verify that the magnetic lock provides sufficient holding force for their application, particularly in areas with drafts or air pressure differentials.

• Rollers: European-sourced rollers support an 80KG load capacity each, enabling smooth and stable operation across the full range of panel sizes. The roller quality directly affects the operational feel of the door—higher capacity rollers maintain consistent rolling resistance over time and resist degradation from daily use. For panels at the upper end of the size range, the 80KG per-roller rating provides a comfortable margin above the actual panel weight, which contributes to long-term reliability. Buyers should confirm the number of rollers per panel, the expected service life under their anticipated usage frequency, and the availability of replacement rollers for future maintenance.

• Buffer / Soft-Close System: The bidirectional buffer technology slows the door panel as it approaches the fully open and fully closed positions, preventing the panel from slamming against the frame or wall. This serves both safety and durability functions: it protects users from finger injuries and reduces mechanical stress on the track, rollers, and frame connections that can result from impact forces. The bidirectional operation means the buffer works whether the user is opening or closing the door. Buyers should confirm whether the buffer resistance can be adjusted for different panel weights or user preferences, and verify that the buffer mechanism is field-serviceable if maintenance is ever required.

• Lock: The magnetic lock point provides a secure holding mechanism that keeps the door panel firmly in the closed position without the need for a mechanical latch that would interrupt the frameless design. Magnetic locks offer the advantage of silent engagement and disengagement, which is valued in quiet environments such as hotel rooms, bedrooms, and home offices. Buyers should confirm the pull force of the magnetic lock to ensure it is sufficient for their application, particularly for exterior-facing installations where wind pressure or air currents could overcome a weak magnetic hold.

• Track System: The concealed track system is the defining hardware component of the 54 Invisible Ghost Sliding Door. Unlike conventional sliding door tracks that remain stationary and visible, this track moves with the door panel, enabling the invisible opening effect. The track must be precisely installed within the wall or ceiling cavity to achieve the intended aesthetic, which requires coordination between the door installer and the framing contractor. Buyers should confirm the track dimensions, the minimum cavity depth required for concealed installation, and whether the track system can be adapted to different wall construction types encountered in their project.

• Sealing / Connection Hardware: Advanced gaskets and sealing components contribute to the door's air tightness rating of approximately 1.2 m³/(m·h) and its 35 dB sound reduction performance. Quality seals prevent drafts, dust infiltration, and noise transmission at the panel perimeter, maintaining comfort in the spaces on either side of the door. Over time, seals can degrade from compression set, UV exposure, or temperature cycling, so the long-term availability of replacement gaskets is an important consideration for building owners and facility managers. Buyers should confirm the seal material composition, expected service life, and availability of replacement seal kits for ongoing maintenance.

Application Scenarios

• Apartment: In apartment living, maximizing usable floor area and maintaining visual openness are constant challenges. The 54 Invisible Ghost Sliding Door addresses both by eliminating the swing radius of hinged doors and the visible tracks of conventional sliders. When closed, the frameless glass panel allows light to pass between rooms; when open, the panel aligns with the wall opening and virtually disappears, freeing the full width of the doorway. This is especially useful for apartment bathrooms, kitchens, and bedroom-to-living-area transitions where every centimeter of clearance matters. Procurement teams specifying doors for apartment developments should confirm the panel size range covers their standard door openings, and coordinate flush floor rail installation with the flooring contractor during the construction phase.

• Home Office: A home office requires acoustic separation from household activity while maintaining the option to open the space when privacy is not needed. The 35 dB sound reduction rating helps muffle conversations, television noise, and kitchen sounds from adjacent rooms, creating a quieter work environment. The frameless design also contributes to a professional, uncluttered appearance that is appropriate for video calls and client-facing home office setups. Buyers should confirm which glass configuration delivers the 35 dB acoustic rating and verify that the magnetic lock provides adequate sound sealing at the door perimeter to maintain the stated performance.

• Hotel: Hospitality projects demand doors that combine aesthetic appeal, acoustic privacy, and reliable operation under high usage frequency. The invisible opening effect creates a premium visual impression in hotel suites, where bathroom or dressing area partitions that seem to vanish enhance the sense of spaciousness. The bidirectional buffer technology protects guests from finger injuries, and the European hardware is engineered for the operational cycles typical of hotel environments. Buyers specifying this door for hotel projects should confirm hardware durability ratings for commercial usage frequency, availability of spare parts for ongoing maintenance, and finish options that coordinate with interior design schemes.

• Office Building: Modern office design increasingly uses glass partitions to maintain visual connectivity while providing acoustic separation for meetings and focused work. The 54 Invisible Ghost Sliding Door serves this purpose with its frameless construction that maximizes light penetration and its approximately 35 dB sound reduction that supports speech privacy in conference rooms and executive offices. The flush floor rail eliminates the channel track that can catch chair casters or create tripping hazards in busy corridors. Procurement teams should verify that the panel size range accommodates their standard office door openings, and confirm whether fire-rated glass configurations are available if code compliance requires them.

• Outdoor: For outdoor or exterior-related projects, buyers should confirm weather resistance, water tightness, wind pressure requirements, surface finish, and installation conditions before ordering. While the door carries ratings of 5000 Pa wind resistance and 700 Pa water tightness, these values were established under controlled test conditions that may differ from actual outdoor exposure. The thermal break design and insulated glass options may support exterior-facing installations in sheltered locations, but the product's primary design intent appears to be interior space division. Buyers considering outdoor applications should discuss specific environmental exposure conditions with DERCHI to confirm suitability.

• Residential Building: In residential construction, the 54 Invisible Ghost Sliding Door is well-suited for bathroom enclosures, kitchen-to-dining transitions, walk-in closet entries, and laundry room partitions. The trip-free flush floor rail is a meaningful safety benefit for homes with children or elderly residents, and the approximately 35 dB sound reduction helps maintain bedroom quiet when bathroom or kitchen noise is present on the other side. The concealed track design also simplifies cleaning compared to exposed sliding door tracks that collect dust and debris. Residential project buyers should confirm that their chosen glass configuration, finish color, and opening direction are available within their project timeline and budget.

• Exterior: For exterior or exterior-facing installations such as enclosed balconies, sunrooms, or sheltered patios, the door's thermal break design and weather performance ratings become critical evaluation factors. The U-value around 2.0 W/(m²·K) and 700 Pa water tightness suggest potential suitability for sheltered exterior applications in temperate climates, but actual performance depends on the specific glass configuration, installation quality, and local weather exposure. Buyers considering exterior applications should confirm with DERCHI that the selected configuration meets the relevant building code requirements for their location, and request test reports documenting performance under conditions representative of their climate zone.

• Villa: High-end residential villas often feature open-plan living areas where visual flow between spaces is a key design priority. The 54 Invisible Ghost Sliding Door supports this aesthetic by allowing partitions to effectively disappear when open, creating uninterrupted sight lines between rooms or between interior spaces and garden views. The minimalist frameless design aligns with the contemporary architectural language common in luxury villas, while the robust performance ratings ensure the door can handle the exposure conditions found in large, open-plan homes. Villa project buyers should confirm the availability of premium finish options and coordinate the flush floor rail installation with the high-end flooring materials typically specified in luxury residential projects.

What to Confirm Before Ordering
