The 28 x 80 interior door from Derchi is a custom aluminum glass swing door engineered for project-based procurement. It pairs a durable 6063-T5 aluminum frame with argon-filled double glazing and HOPO hardware, delivering improved thermal and acoustic performance compared to standard hollow-core doors. The door is manufactured to exact dimensions, not a stock item.
- Made to order for the 28 x 80 inch (711 x 2032 mm) opening within a 350–1100 mm W x 800–2800 mm H range.
- Features 5 mm tempered glass, 103 mm frame, and multi-point lock for modern interiors.
- Suitable for hotels, offices, apartments, and villas; backed by full technical documentation.
Product Details
The 28 x 80 interior door features a 103 mm wide 6063-T5 aluminum frame built with 2.0 mm thick profiles (upgradable to 2.2 mm). The insulated glass unit—5 mm tempered + 27 mm argon-filled cavity + 5 mm tempered—reduces heat transfer and dampens sound, significantly outperforming lightweight hollow-core doors. Continuous EPDM gaskets around the panel and frame improve air tightness and acoustic isolation, while the PVDF aluminum spacer with molecular sieve prevents condensation, keeping the view clear.
Designed as a custom aluminum glass swing door manufacturer solution, this model suits interior partitions where daylight and quiet matter—from hotel suites to office meeting rooms. Buyers can specify single, double, or parent-child swing configurations. Every order is backed by engineering support, including CAD/BIM details, shop drawings, and installation guides, making it a reliable choice for contractors and developers who need 28 x 80 glass door wholesale supply without compromising on documentation.
Product Features
Argon-filled Double Glazing: The 5+27A+5 mm tempered unit effectively cuts heat transfer and noise, helping maintain indoor comfort and lower HVAC loads in corridors, meeting rooms, or hotel suites.
Robust 6063-T5 Frame: With a 103 mm width and 2.0 mm wall thickness (2.2 mm optional), the frame resists bending and warping far better than wood or thin metal, ensuring long-term durability.
Multi-point Locking System: HOPO hardware engages at multiple points, pulling the panel tight against EPDM seals for enhanced security and consistent air tightness, unlike single-latch interior doors.
EPDM Sealing: Continuous gaskets around the door leaf and frame form a flexible barrier against drafts and sound, performing well through thermal expansion and frequent use.
HOPO SS304 Hardware: Stainless steel hinges and handles in black or silver deliver smooth operation and corrosion resistance, suitable for high-traffic commercial doors where reliability matters.
Made-to-Order Configuration: Every custom aluminum interior door is built to your supplied dimensions, glass type, and color—no off-the-shelf compromise; simply submit your project specifications.
Customizable Styles
Glass Options: Clear, frosted, tinted, and Low-E glass choices are available; please confirm Low-E compatibility with the argon-filled unit to maintain thermal performance.
Frame Colors: Marble Black, Sand Grey, Light Coffee, White are standard. Custom RAL colors like Indigo or Soft Gold can be ordered for branding consistency.
Size Range: The 28 x 80 inch opening fits our 350–1100 mm W x 800–2800 mm H range; specify your exact rough opening for a made-to-measure door.
Opening Styles: Choose single swing, double swing, or parent-child swing to suit corridor widths and traffic patterns in your project.
Lower Panel: A solid aluminum lower panel can replace glass for privacy in bathrooms or bedrooms while keeping the upper glazed vision light.
Hardware Accessories
HOPO SS304 Hinges: Durable stainless steel hinges support panel weight; the exact number is specified per door size and configuration.
HOPO Multi-point Lock: The integrated lock engages multiple latching points for a secure close and uniform compression of the EPDM seal.
HOPO Door Handles: Black or silver lever handles with standard backset; confirm handing and any accessibility requirements at order placement.
EPDM Gasket System: Factory-bonded EPDM gaskets act as a critical sealing component, reducing air and sound leakage around the door’s perimeter.
Optional Accessories: Floor stop, concealed closer, or kick plate can be added; inquire to verify compatibility with your chosen swing type and frame.
