AS ONE WISHES Residence: Window And Door Project in Qujing, Yunnan, China

AS ONE WISHES Residence Window and Door Project, Qujing, Yunnan, China

Based on the excellent performance of DERCHI Windows and Doors in high-end residential projects, here are the key advantages of the products, as delivered for the AS ONE WISHES residence in Qujing, Yunnan Province, China — a development where around nine out of ten households chose DERCHI:

DERCHI Windows and Doors: A Whole-Community Solution at AS ONE WISHES

When the AS ONE WISHES residence was completed, one number stood out: roughly 90% of the households in the development chose DERCHI windows and doors. In a market where owners compare specifications closely, that result reflects a simple reality — the performance, finish and detailing that satisfy one apartment also hold up across an entire high-rise community in China, Asia's largest residential market.

1. A Decision Made House by House, Not by the Developer

The specification was not simply handed down. Households were free to choose, and the overwhelming majority reached the same conclusion.

Around 90% of Households Chose DERCHI: Nine out of ten families in the development selected DERCHI — a level of take-up that is unusual in a competitive residential market and that reflects owner-level trust rather than a paperwork decision.

Consistency Across Every Elevation: Because so many households specified the same brand, the elevations read as one system: the same frame colour, the same sightlines and the same proportions, floor after floor.

A Reference for Neighbouring Projects: A high-rise community where most owners independently choose the same supplier becomes its own reference — the clearest possible evidence of how the products perform in daily use.

2. Complete Coverage: Every Opening in the Home

The project covered the full range of openings found in a large-format apartment, not just one window type.

Large-Format Sliding Doors for Living and Dining Areas: Multi-panel sliding doors open the living space onto the balcony, with slim frames that keep the glass area dominant and the view uninterrupted.

Inward-Opening Casement Windows for Bedrooms: Bedrooms use casement windows with a large fixed pane flanked by operable sashes — daylight and ventilation without losing the wide, clean elevation.

Sliding Windows with Insect Screens for Kitchens: Kitchens are served by sliding windows fitted with insect screens, keeping ventilation practical and the interior free of insects.

Corner Glazing and Fixed Panes: Corner windows and fixed panels extend the glazed area around the room, turning the apartment's outlook into part of the interior.

3. Security as a Structural Feature

In a high-rise residence, security and wind resistance are engineering questions, not add-ons.

Patented Four-Side Six-Point Locking: Our patented locking system engages on all four sides of the operable panel at six points, so the sash closes as a solid, fully engaged unit rather than relying on a single latch.

Profile Wall Thickness Above the Standard: Frame profiles use wall thickness above the national standard, giving large sashes the rigidity to stay square, resist deformation and hold their performance over years of use.

Engineered for Upper-Floor Wind Loads: Upper floors of a high-rise see substantially higher wind pressure than ground level. Reinforced profiles and corner-crimped joints are engineered to carry those loads without flexing or rattling.

4. Hardware and Everyday Reliability

Windows and doors are one of the few building components a resident touches every single day.

Wehag Hardware Package: The hardware package is built around Wehag components, selected for smooth operation and long service life rather than lowest cost.

Antibacterial-Coated Handles: Handles carry an antibacterial coating — a small detail that matters on a surface every member of the household touches.

Tested Through Hundreds of Thousands of Cycles: Operable elements are tested through hundreds of thousands of opening and closing cycles, so the feel of the window on day one is still the feel of the window years later.

5. Five Performance Dimensions, One Envelope

Specifying windows and doors is not about one headline number. It is about several performance dimensions holding together at once.

Water and Air Tightness: Multi-stage sealing and a drained-and-vented principle keep wind-driven rain and draughts outside, even on exposed upper floors.

Thermal and Acoustic Insulation: Thermal-break profiles and insulated glazing reduce heat transfer, while the same construction limits exterior noise — quieter rooms and lower energy demand in the same package.

Wind Resistance and Structural Stability: Reinforced frames and engineered fixings maintain the envelope's integrity under sustained wind pressure, protecting both comfort and the building fabric.

6. One Aesthetic Across the Whole Home

Because every opening came from the same system, the interior reads as one design decision rather than a collection of separate purchases.

Matched Frames, Colours and Sightlines: Sliding doors, casement windows and sliding windows share frame depth, colour and proportions, so the joinery looks intentional from every angle.

Performance Balanced Room to Room: Thermal, acoustic and weather performance remain consistent between a bedroom window and a living-room slider — no weak link in the envelope.

7. Certification, Manufacturing and Project Support

For a development of this scale, product credentials and supply reliability matter as much as the hardware itself.

International Certifications: Products are manufactured to international standards with third-party verified performance data available for specification.

25+ Years of Manufacturing Experience: More than two decades of production give large residential projects a supply chain used to consistent output and reliable delivery schedules.

One-to-One Project Support: Projects are handled by a dedicated specialist from initial drawings through to delivery, backed by warranty coverage on frames, hardware and finishes.

Conclusion

When nine out of ten households in the same development independently choose the same window and door brand, that is not a coincidence — it is a verdict. At the AS ONE WISHES residence, DERCHI supplied a complete, consistent envelope: sliding doors, casement windows, sliding windows and fixed glazing, built around the same security, weather and thermal performance in every apartment, from the ground floor to the top.
