For office partitions, hotel suites, and multi-unit builds, 72 x 80 interior french doors combine aluminum framing and tempered glass to achieve a clean, open separation. DERCHI configures each double‑door system to project dimensions and performance needs—no fixed‑stock compromise. Factory‑direct production keeps the specification flexible while maintaining quality control.
- Engineered to match a 72 x 80 in rough opening with two 36 in panels
- 6063‑T5 aluminum frame, slim profile, corrosion‑resistant
- Standard double‑glazed tempered unit with argon and warm‑edge spacer
- B2B supply chain with RFQ, export packing, and installation support
Product Details
An 80 mm deep 6063‑T5 aluminum frame with 2.0 mm wall thickness serves as the structural core. It holds large insulated glass units without distorting, even in busy corridors. The two‑panel layout—equal halves hinged or folding centrally—fits the 72‑inch rough opening neatly and simplifies install. Because aluminum won’t swell, warp, or need repainting like wood, these doors cut maintenance costs for facilities teams.
Glass selection drives thermal and acoustic performance. The base unit uses 5 mm tempered glass, an argon‑filled cavity, and PVDF warm‑edge spacer to limit condensation. Project‑specific upgrades—Low‑E, laminated for sound, frosted, tinted, triple‑glazed—allow the door to meet energy codes or privacy requirements. Seals, hardware, and finishes are chosen per order, ensuring reliable operation in dry offices or condominium entries with higher humidity.
Product Features
2.0 mm aluminum extrusions: Heavy glass panels sit securely; door leaves stay aligned without deflection, even in high‑traffic settings.
Glass flexibility: Combine tempered, Low‑E, laminated, or frosted glazing with argon to control heat, light, and occupant comfort.
Multi‑point locks: Top, bottom, and side locks engage together, securing the door more evenly and reducing air leakage.
Cured finishes: Powder coat or fluorocarbon coatings in standard colors (e.g., Black Crystal Stone) or custom RAL resist scratching and fading at busy entry points.
North American sizing: The 72‑by‑80 configuration matches common rough openings, cutting on‑site framing time.
Opening style options: Center‑split swing, single‑side swing, or folding—hardware and tracks chosen for the space’s traffic pattern.
Customizable Styles
Glazing: Choose clear, frosted, Low‑E, tinted, laminated; add double or triple panes for energy savings or acoustic control.
Finishes: Standard palette—Caramel Coffee, Deep Coffee, Black Crystal Stone, Quartz Gray—plus RAL custom colors for branding.
Size range: Non‑standard widths and heights are possible; confirm fabrication limits with DERCHI engineers.
Configuration: Center‑split double, single active leaf with sidelight, or bi‑fold—to suit the floor plan.
Thresholds & jambs: Discuss flush, low‑profile, or raised thresholds; jambs can mate with drywall, masonry, or curtain wall systems.
Hardware Accessories
CMECH handles: Lever or pull styles in multiple finishes; built for high‑cycle use and multi‑point lock integration.
Hinges: Stainless steel, sized for the weight of thick aluminum and insulated glass, ensuring smooth swing or fold over years of use.
Multi‑point locks: Simultaneous top, bottom, and side engagement for a uniform seal and better security.
Rollers: Precision bottom rollers for folding setups, low‑friction and quiet operation.
Flush & floor bolts: Surface or concealed, they lock the inactive leaf while maintaining the double‑door look.
Basic Parameters
Performance Item | Available Information | Buyer Notes |
|---|---|---|
Thermal Insulation | Depends on glass package; U‑factor and SHGC values are not pre‑rated. | Request project‑specific thermal data if code compliance is required. |
Wind Pressure Resistance | Primarily relevant to exterior applications; no standard interior rating. | Confirm structural calculations if doors face building envelope pressure. |
Water Tightness | Not rated for interior use; EPDM seals provide basic moisture resistance. | In wet or semi‑exterior locations, request seal and drainage options. |
Air Tightness | Multi‑point locks and gaskets reduce leakage; no published class. | Request infiltration test data for energy‑sensitive or pressurized spaces. |
Sound Insulation | Depends on glass; STC not published. | Specify noise goals early—laminated glass yields meaningful sound reduction. |

Advantages
Factory‑direct sourcing: Buying from DERCHI’s Foshan plant removes intermediary markups, freeing budget for upgraded glass or hardware.
Project‑specific build: Every door is built to order, so the final spec matches your drawings, not a catalog’s limit.
Scalable capacity: With an approx 180,000 sqm facility and 300,000 sqm annual output, DERCHI handles bulk orders and phased deliveries for large developments.
Technical support: Shop drawings, CAD/BIM files, and installation guidance come after order, so project teams can coordinate early.
Low‑maintenance aluminum: Aluminum resists swelling, warping, and repainting, lowering long‑term maintenance bills for property managers.
Application Scenarios
Apartment: Separate a home office from the living area without losing daylight. Frosted glass panels preserve privacy while slim frames keep sightlines open.
Home Office: Create a quiet, professional transition from hallway to workspace. Laminated glass cuts noise transmission, and clear or Low‑E panes maintain a visual link when needed.
Hotel: Double‑door entries in suites or spas create a sense of arrival. Black Crystal Stone finishes and custom glazing reinforce brand image, and multi‑point locks meet security requirements reliably.
Office Building: Enclose conference rooms without blocking sightlines. Swing or folding configurations adapt to narrow corridors; energy‑efficient glass can help manage HVAC loads in large floor plates.
Outdoor (semi‑exterior): In covered terraces or balcony thresholds, aluminum frames resist corrosion better than steel. Verify water‑tightness ratings, gasket upgrades, and coating durability for such locations.
Residential Building: Standardize unit entries with a consistent 72‑by‑80 opening. Pre‑finished aluminum doors ship ready for fast installation floor after floor.
Exterior: When the door faces the building envelope, it must handle wind, water, and thermal demands. Request U‑factor, wind load, and water penetration data before specifying for facade‑facing locations.
Villa: Custom RAL colors and decorative glass inserts let high‑end homes match door aesthetics to stone, timber, or curtain wall finishes. The aluminum construction requires virtually no upkeep beyond occasional cleaning.
FAQ
What are 72 x 80 interior french doors?
These are double‑door sets—usually two 36‑inch panels hinged or folding—for a 72 x 80 inch opening. DERCHI builds them from aluminum and tempered glass, tailored to project specifications for interior use.
Where can these doors be used?
Office corridors, hotel suites, apartment entries, retail partitions, school classrooms—anywhere you need distinct zones that still share light.
Can the doors be customized beyond 72 x 80?
Absolutely. Glass, color, hardware, opening style, and non‑standard dimensions are all negotiable. Each order is project‑based; send your sizes and requirements for a proposal.
What information is needed for a quotation?
Rough opening dimensions, glass type, color, opening configuration, and quantity. If you have acoustic or energy targets, share those too—it speeds up the quote.
Do you support B2B projects and bulk orders?
Yes. We supply contractors, developers, and distributors factory‑direct. Volume pricing, export packing, and technical docs are part of the package.
Are technical documents like CAD or BIM files available?
Yes. Shop drawings, CAD, and BIM files follow order confirmation. Let us know your format and timeline early so we can align.
What should buyers confirm before ordering?
Double‑check rough opening measurements, match glass specs to local codes, and lock in hardware and RAL colors. A signed approval drawing helps avoid field surprises.
How are certifications, packaging, and shipping handled?
Certifications like NFRC or CE are issued per project; ask early. Export‑grade plywood crating or palletizing is arranged, and we coordinate shipping from Foshan. Lead time and Incoterms are confirmed with your quote.
