DERCHI's 36 x 80 exterior door is a custom aluminum entry system tailored for project openings. It's available in pivot, hidden hinge, and hinged configurations, all built around thermal break frames and high-performance hardware. Whether for a villa, hotel, or commercial lobby, this door combines energy efficiency, sound control, and long-term durability.
- W-Z3 pivot version delivers a verified U-factor of 0.38, air infiltration 1.2 m³/(m·h), and 35 dB sound insulation.
- Custom quotation based on project specs: sample stage, small-batch trial, and bulk after BOM confirmation.
- Multiple series let you match architectural style and performance requirements.
Product Details
This entry door is engineered around 6063-T5 aluminum thermal break profiles, with frame thicknesses from 3.0 mm to 5.0 mm depending on the series. The pivot door's frame uses a 3.0 mm thermal break, while the hidden hinge door steps up to a 5.0 mm aluminum frame for added strength. Front and back panels differ by series: the W-Z3 is an all-glass pivot door, while the hidden hinge version features 4+4 mm aviation aluminum carved plates on the exterior and a 12 mm OSB back panel. The hinge series mirrors this plate-and-OSB construction, with a bottom reinforced by 304 stainless steel and a 1.8 mm magnesium alloy steel plate. Internally, each door may incorporate aluminum honeycomb, polyurethane insulation, and fire-resistant cotton to boost rigidity and thermal performance.
Because every order is project-based, slab dimensions, opening direction, and hardware are all matched to your drawings, not taken from stock.
Product Features
W-Z3's U-factor of 0.38 and SHGC 0.22 help reduce energy loads in conditioned buildings.
35 dB sound insulation (W-Z3) helps create quieter interiors, important for hospitality and residential projects.
Flexible glass configurations: choose from double tempered, Low-E, laminated, tinted, reflective, or even bullet-proof glass.
Hardware systems include German-imported 304 stainless steel hinges, multi-point locks, and smart lock options for reliable security.
Multiple opening styles — pivot, hidden hinge, and standard hinge — suit various layouts.
Weather-resistant details: EPDM seals, bottom drainage, and corrosion-resistant materials protect against moisture and wind.
Customizable Styles
Glass selection: argon-filled double tempered (W-Z3), Low-E, laminated, reflective, tinted, bullet-proof — final spec decided during inquiry.
Frame finish: powder coating, Galaxy coating, wood grain, carved aluminum panels. Color charts available on request.
Exact size: While the nominal is 36x80, slab and frame dimensions are custom. Rough opening guide is 38″×82.5″, but confirm per project.
Surface color: Hidden hinge series comes in 13 colors; other series have palettes to be confirmed.
Opening setup: inswing/outswing, pivot direction, and single/double door configuration defined by architectural requirements.
Hardware Accessories
Handles: stainless steel or zinc alloy, set at 1000–1200 mm height and 32–38 mm width per project ergonomics.
Hinges: hidden hinge uses a concealed pivot; the hinge series uses German-made 304 stainless steel hinges rated for 150 kg and 100,000 cycles.
Locking systems: multi-point locks, electric lock bodies (408/388/358/280/240/260), smart locks (S8/S9 with fingerprint, password, IC card) are available.
Pivot mechanism: center-axis pivot with ground spring N/NH; confirm axis position for proper operation.
Sealing: EPDM rubber weatherstrips, thermally broken sills, and integrated astragals improve air and water resistance.
