The DERCHI W-Z3 pivot door brings together thermal-break aluminum and double tempered insulating glass to form a modern glass exterior door system engineered for large-scale commercial and residential projects. Its concealed pivot hardware allows uninterrupted glass sightlines while delivering consistent weather protection and energy efficiency.
- Wind load resistance rated up to 5 kPa and water tightness of 700 Pa (consult factory for test standards).
- Argon-filled 8mm+21A+8mm insulating glass contributes to a manufacturer-measured U-Factor of 0.38 (NFRC report available on request).
- Project-configurable dimensions, glass type, frame finish, and pivot placement.
Product Details
The structural core of the W-Z3 is a 129mm-wide thermal-break aluminum frame. Sash profiles measure 3.0mm thick, while the frame uses 2.5mm aluminum—enough to carry large insulated glass panels without excess deflection. The standard glazing is a double tempered insulating unit (8mm+21A+8mm) filled with argon, which curbs heat transfer and supports the door’s U-Factor of 0.38.
Concealed top and bottom pivot hardware bears the door’s weight and allows smooth rotation. Because there is no exposed floor track, the threshold can be kept almost flush when designed accordingly. Perimeter sealing relies on multi-layer EPDM gaskets, and the corners are joined with 45° injection bonding—a detail that helps the assembly achieve its water tightness rating of 700 Pa. Air tightness is 1.2 m³/(m·h) and sound insulation reaches 35 dB, though buyers should confirm the specific testing standards used and their alignment with local code requirements.
Product Features
Pivot Opening: The concealed pivot hardware supports oversize glass panels with minimal visible framework, giving façades a clean, contemporary line that suits upscale residential and commercial entries.
Thermal Performance: Argon-filled insulating glass and a thermal-break frame work together to limit heat gain/loss; the measured U-Factor of 0.38 (to be verified via NFRC report) can help reduce building HVAC demand.
Frame Sturdiness: With a 129mm frame width and 3.0mm sash walls, the structure resists bowing and keeps the pivot movement smooth—even on tall or wide openings.
Weather Sealing: Multi-layer EPDM gaskets and injection-bonded corners deliver a tested water tightness of 700 Pa, keeping rain out in exposed locations.
Urban Sound Control: Manufacturer-tested 35 dB sound insulation helps dampen street noise, a practical advantage for hotels, offices, and downtown apartments.
Project Customization: Glass type, frame finish, pivot offset, and dimensions are all adjustable to suit architectural drawings, so the door fits specific performance and aesthetic briefs.
Customizable Styles
Glass Configuration: Clear, tinted, reflective, or low-E coatings are available; request SHGC and visible light transmission data from the factory.
Frame Color & Finish: Powder coating, anodizing, or wood-grain transfer in a range of RAL colors. Sample approval before production is recommended.
Pivot Position: Choose center or off-center pivot placement to match door width and swing path; affects clear opening dimensions and visual balance.
Size Range: No preset maximum; each opening is reviewed structurally against project drawings to determine safe dimensions.
Threshold & Sill Design: Low-profile or weather-rated sill options available; clarify accessibility and drainage needs early in the quotation process.
Hardware Accessories
Concealed Pivot System: Top- and bottom-mounted pivot units are hidden inside the frame and floor, enabling a clean look; load capacity should be confirmed per door weight.
Handle/Grab Bar: Guangqi handles or other models can be specified; finish coordinates with door frame and interior hardware scheme.
Multi-Point Locking: Lock body and strike points are customizable; cylinder upgrades available—discuss security requirements during ordering.
Bottom Guide/Closer: A concealed floor guide or overhead closer can be integrated for controlled closing and wind resistance; confirm operational needs with factory.
EPDM Gaskets: Multi-layer corner-molded gaskets maintain consistent compression around the entire leaf, supporting air and water ratings.

Application Scenarios
Apartment: Upscale lobbies gain daylight and a sense of openness; sound insulation helps buffer common-area noise.
Home Office: A pivot entry visually separates the workspace, maintaining daylight and thermal comfort.
Hotel: Tailor door height and glass to create a striking atrium effect; the concealed pivot keeps the design refined.
Office Building: High-traffic entry with thermal-break helps the building envelope meet air tightness and energy targets.
Outdoor: For patio/garden exits, review wind and water ratings against local exposure; inquire about coastal-grade finishes.
Residential Building: Multi-unit developments benefit from repeatable fabrication and configurable sizes for consistent entry design.

Villa: Large-format pivot door becomes a focal point, blending interiors and landscape with clear or low-E glass while managing solar gain.
FAQ
What exactly is the W-Z3 pivot door?
The W-Z3 is an aluminum pivot door with thermal-break frame and double tempered insulating glass. It’s designed for modern glass exterior door applications where large openings, energy performance, and clean lines are priorities.
How customizable is this door?
Nearly every element can be adjusted: dimensions, glass type (clear, tinted, low-E), frame color and finish, pivot position, hardware, and locking. The factory reviews your drawings and performance targets to confirm feasibility.
What do I need to provide to get a quotation?
Submit rough opening dimensions, door swing direction, pivot preference, glass and finish requirements, target performance levels, project quantity, and any certification needs (e.g., NFRC, CE). This allows the supplier to prepare an accurate offer.
Are there test reports for the performance values?
Manufacturer test data for wind load (5 kPa), water tightness (700 Pa), air tightness (1.2 m³/(m·h)), and sound insulation (35 dB) are available. For U-Factor (0.38) and SHGC (0.22), request an NFRC or equivalent report for your specific glass configuration; these are generated per project when needed.
What should I confirm before placing an order?
Finalized door weight and structural feasibility, alignment of test standards with local codes, finish sample approval, lock specifications, and any third-party inspection requirements. Also clarify lead time and warranty terms in the contract.
How is packaging and shipping handled?
Packaging methods (palletized, crated, paper-wrapped) are decided during order confirmation. Trade terms (FOB, CIF, etc.) are agreed in the contract, and a packing list is provided before dispatch.
