DERCHI supplies modern aluminium interior doors in sliding, swing, and bifold styles, built around 6063-T5 frames and tempered glass. These doors partition interiors efficiently while letting light pass through and keeping noise at bay.
- Frames: 6063-T5 aluminium, resistant to warping and corrosion compared to timber or steel
- Glass: 8 mm single tempered or double‑glazed units with Low‑E and argon
- Performance: up to 37 dB sound reduction; U‑factor as low as 0.28
Product Details
Aluminium interior doors from DERCHI are built on precision‑extruded 6063‑T5 profiles that stay dimensionally stable in varying interior climates, avoiding the cracking and swelling common to wood. The line‑up includes sliding, swing, and bifold configurations, each offering a different balance of opening width, stack‑away space, and acoustic separation. Framing from 1.4 mm to 2.0 mm wall thickness supports daily use in hotels, offices, and residential projects.
Glazing choices range from 8 mm single tempered glass (for minimal framing sightlines) to 5 mm + 27A + 5 mm double‑glazed units filled with argon. Laboratory testing shows sound insulation values between 32 dB and 37 dB and whole‑door U‑factors as low as 0.28. The P103 swing door adds a 35 mm polyamide thermal break to control condensation and heat loss. Each door is assembled with hardware matched to the frame finish, yielding smooth operation and a uniform appearance.
Product Features
Slim‑Profile Aluminium Sliding Doors: Narrow stile profiles increase the visible glass area, so rooms feel more open, while 1.4–2.0 mm extrusions handle heavy daily traffic without deflection.
Interior Glass Doors with Acoustic Control: Double‑glazed, argon‑filled panels with optional laminated glass suppress sound up to 37 dB, making them suitable for meeting rooms and bedroom suites.
Aluminum Bifold Doors: The 80 Series bifold system folds panels neatly to one side, creating a wide, uninterrupted opening for restaurants, hotel suites, and flexible commercial partitions.
Modern Interior Partitions for Open Plans: Sliding and folding configurations let users reconfigure work and living areas on demand, balancing privacy with openness and maintaining natural light flow.
Commercial Interior Doors with Durable Hardware: Sealed‑bearing double rollers and multi‑point locks are engineered for corridors and lobbies, reducing maintenance intervals and keeping operational noise low.
Customizable Thermal Performance: U‑factors from 0.28 to 0.39 allow specifiers to match the door's thermal resistance to local codes by selecting glass makeups and frame designs, without sacrificing the look of the building.
Customizable Styles
Frame Finish: Powder coat or anodize to any RAL tone, woodgrain, or brushed metal effect. Custom matched colors are available on project basis.
Glass Configuration: Single tempered, double glazed, Low‑E, laminated, frosted, or tinted glass. Glass thickness and spacer options are adjusted per project requirement.
Track Layout for Aluminium Sliding Doors: Two‑track, three‑track, or bypass systems with optional soft‑close mechanisms; pocket door configurations also possible.
Opening Style and Direction: Sliding, swing (single/double), bifold (single/double/center fold). Swing doors can open inward or outward; bifold folding direction can be specified.
Size and Threshold Options: Door leaf dimensions customized to structural openings. Low or zero‑threshold options support accessibility; consult factory for maximum panel weights.
Hardware Accessories
The black solid aluminium handle—standard on 10 Series—gives a slim, clean grip that complements the minimal frame.
Hardwearing rollers with sealed bearings deliver smooth, quiet travel across the track system, even after prolonged use.
An optional buffer dampens the door's approach to the jamb, preventing impact and protecting glass edges.
A three‑way linkage kit lets multi‑panel sliders operate as one; moving one panel shifts the rest in sync.
Swing doors carry multi‑point locks with dust‑proof strike plates; fingerprint or combination locks are offered on P103 models.

Advantages
Factory‑Direct Procurement: Buyers work directly with the Foshan factory, which has 25+ years in aluminium fenestration. This cuts out intermediary mark‑ups for volume orders.
Project‑Ready Documentation: Shop drawings, CAD/BIM files, performance data packs, and physical samples are supplied early in the project to support specification and compliance checks.
Stable Aluminium Frames: The 6063‑T5 alloy resists corrosion and stays dimensionally stable in interior environments, giving it an edge over timber and steel in longevity.
Full Customization: Frame dimensions, glass type, track layout, and finish can all be adjusted to match the architectural drawings, using factory‑approved components and processes.
Global Logistics: Wooden crate packaging and a choice of trade terms (FOB, CIF, DDP) help deliver orders safely to project sites across the 100+ countries the factory currently serves.
Application Scenarios
Apartment: In compact apartments, sliding aluminium doors define zones without blocking daylight. The slim frames keep sightlines long, making the whole unit feel larger.
Home Office: A home office requires speech privacy for focused work. A sound‑rated glass door isolates phone calls and video meetings while maintaining a visual link to the home.
Hotel: Hotel suites use bifold and sliding doors to transform a single open area into separate sleeping and living rooms. Acoustic ratings up to 37 dB confirm the privacy guests expect.
Office Building: In modern offices, glass‑fronted meeting rooms with aluminium frames keep corridors bright. The doors can be reconfigured as team sizes change, with no structural work required.
Outdoor: For covered patios or balconies, the 135D sliding door works as a semi‑exterior system. The PVDF coating and tested water tightness (350 Pa) give it an edge over standard interior doors, but wind and weather exposure must be assessed with the factory.
Residential Building: In multi‑family housing, aluminium sliding doors last longer than timber in high‑humidity environments like laundry rooms or common corridors, reducing the maintenance load on building management.
Exterior: The 135D can be used in lightly protected exterior locations if wind and water ratings are verified. DERCHI can advise on seal upgrades and installation details for partial weather exposure.
Villa: Large aluminium bifold and swing doors connect villa living areas to gardens, allowing uninterrupted views. Heavy glass panels up to 150 kg are supported by robust hinges and framed sightlines that stay narrow.
FAQ
What are modern aluminium interior doors?
They are interior door systems with extruded 6063‑T5 aluminium frames and tempered glass infills, available as sliding, swing, or bifold units. They separate spaces while letting in daylight and providing a contemporary look.
Where can modern aluminium interior doors be used?
Commonly installed in hotels, offices, apartments, villas, and retail interiors. They work as room dividers, corridor enclosures, or balcony partitions where light transfer is wanted.
Can the doors be customized for my project?
Yes. Dimensions, glass type, frame color, track layout, and hardware can be specified. DERCHI provides technical drawings and samples during the design phase to confirm fit and finish.
What information is needed for a quote?
Provide door opening dimensions, the required quantity, preferred style (sliding, swing, bifold), glass specification, and any performance targets. A detailed proposal with pricing and lead time will follow.
Can these doors be used for B2B commercial projects?
Certainly. The factory supplies bulk orders to developers, contractors, and hotel groups. Performance test reports and compliance documentation can be included, and on‑site support be arranged as needed.
Are technical documents and test reports available?
Yes, shop drawings, CAD/BIM files, and acoustic or thermal test reports for specific configurations are available during project evaluation.
What should buyers confirm before ordering?
Confirm exact opening dimensions, site handling logistics, desired hardware finish, and any local code requirements (e.g., fire rating if applicable). Addressing these early helps avoid rework.
How are packaging, shipping, and certifications handled?
Doors are packed in wooden crates with protective films. DERCHI can ship under FOB, CIF, or DDP terms. Certification documents (CE, NFRC, etc.) must be requested for the specific model and destination; ask for certificate numbers before ordering.
