Each system represents rigorous extrusion accuracy, thermal separation technology, and high-performance structural glazing engineered to integrate seamlessly into picture window framing and mixed-facade elevations.
Unlike operable casements or sliding units, non-venting picture and fixed architectural glass windows function as integral structural diaphragms within building building envelopes. Designing an uncompromised OEM/ODM fixed window system requires precision balance across structural load calculations, glass deflection, thermal conductivity, and dynamic air/water tight barriers.
DERCHI extrudes high-purity 6063-T5 and structural-grade 6061-T6 virgin aluminum billets. For oversized picture windows spanning up to 4500mm high, internal reinforcement ribs and heavy moment of inertia (Ix & Iy) values ensure wall-deflection limits remain strictly within L/175 under 3500 Pa extreme wind-load pressures.
To eliminate interior condensation and reduce overall building cooling and heating loads, our fixed windows utilize multi-cavity PA66-GF25 (25% glass fiber reinforced polyamide) thermal break strips. This physical mechanical isolation disconnects exterior ambient thermal extremes from conditioned interior environments.
Fixed glass windows command the largest surface area in modern envelope facades. We configure custom Insulated Glass Units (IGU) incorporating triple-pane Low-E coatings, argon or krypton inert gas fills, warm-edge stainless steel spacers, and acoustic PVB or SentryGlas® laminated interlayer plies.

Operating under Guangdong Dejiyoupin Doors and Windows Co., Ltd., DERCHI stands as a Top 10 Chinese fenestration manufacturer with over a quarter-century of advanced manufacturing expertise, serving custom commercial and residential developments across the United States, Canada, Australia, and the Middle East.
Our expansive smart manufacturing complex houses automated CNC multi-axis extrusion machining centers, robotic precision corner crimpers, and dust-free automated IGU sealing lines ensuring continuous high-capacity output and tight dimensional tolerances within ±0.5mm.
Engineered to satisfy demanding regional building codes. Our window and door systems hold CE, ISO 9001, AS 2047 (N6 cyclonic rated), NFRC energy certifications, and UL fire-rated standards, accompanied by more than 30 dedicated utility and design patents.
For more than two and a half decades, we have bridged the gap between architectural concept design and jobsite installation. Our senior engineering staff evaluates structural wind loads, seismic movements, and thermal expansion dynamics for every custom order.
Eliminate project ambiguity before production begins. For every tender, contract, or rough opening schedule, our technical design department provides complimentary, fully dimensioned CAD elevations, glass schedules, and structural anchoring detail sets.
Overseas transit security is paramount. Fixed architectural glass and aluminum frames are packaged with protective anti-scratch films, high-density edge bumpers, desiccant air bags, and encapsulated in reinforced fumigated solid-plywood steel-strapped crates.
Bilingual architectural project managers operate synchronously with Eastern and Pacific standard business hours. Receive immediate technical consultations, responsive BOM updates, and end-to-end import document coordination directly with your freight forwarder.
As stringent energy conservation standards like ASHRAE 90.1, Title 24, and the International Energy Conservation Code (IECC) take hold globally, the role of fixed picture windows is evolving from a mere decorative element into an active energy-regulating building envelope.
The fenestration sector is moving toward Vacuum Insulated Glass (VIG) assemblies integrated within slim aluminum fixed frames. By replacing traditional inert gas chambers with a microscopic thermal vacuum gap, 8.3mm VIG units match the center-of-glass insulation values of thick triple-pane glazing (U-values below 0.10 BTU/hr·ft²·°F), slashing overall dead-load weight by 60%.
Architects increasingly demand minimalist, flush-perimeter fixed glass windows where the frame is concealed inside surrounding ceiling drywall and perimeter stone reveals. Known as "pocket-glazed" or "frameless" fixed picture walls, these configurations deliver 98% uninterrupted clear view ratios while sustaining severe building deflection tolerances.
High on-site labor rates across North America, the UK, and Australasia are driving a decisive shift toward 100% factory-glazed, unitized window frames. Field-installing fragile monolithic glass sheets is being replaced by pre-glazed fixed window panels delivered in sequence, complete with perimeter flashings and factory-cured silicone seals.
