Anatomy of Modern OEM/ODM Aluminium Swing Fenestration
Aluminium swing windows (also referenced globally as side-hung casement windows or architectural outswing/inswing fenestration) represent the gold standard in structural air-tightness, positive water-shedding, and security. Below is a comprehensive engineering breakdown for procurement specialists and architects.
Alloy Metallurgy & Billet Purity
DERCHI OEM extrusion systems are built exclusively utilizing high-purity virgin 6063-T5 or 6063-T6 architectural aluminium billets. With magnesium (0.45–0.9%) and silicon (0.2–0.6%) micro-alloys rigorously controlled, profiles exhibit minimum tensile strength of 205 MPa and yield strength beyond 160 MPa, ensuring structural stability without deflection under negative coastal wind loads.
Isothermal Thermal Break Science
Thermal bridge elimination is achieved through multi-chambered Polyamide PA66 reinforced with 25% glass fibre (PA66GF25). The continuous thermal struts match aluminium's thermal expansion coefficient (2.3 × 10⁻⁵ K⁻¹), completely stopping interior condensation while achieving overall thermal transmittance values (U-values) as low as 1.2 to 1.6 W/(m²·K).
Perimeter Tri-Gasket Sealing
Unlike sliding configurations that rely on brush pile seals prone to air infiltration, our aluminium swing sash compresses three continuous vulcanized EPDM or TPE cellular rubber gaskets upon closure. This creates an airtight isobaric decompression chamber that achieves Class 4 airtightness (EN 12207) and Class 9A watertightness (EN 12208, 600 Pa without leakage).
Empirical Verification
Performance Benchmark Comparison
Data derived from rigorous laboratory testing (AS2047 / ASTM E283 / ASTM E331 / AAMA 101 standards) illustrating how DERCHI OEM systems eliminate systemic building envelope failures.

|---|---|---|---|---|
| Thermal Transmittance (U-Value) | 4.5 – 5.8 W/(m²·K) | 2.2 – 2.8 W/(m²·K) | 1.1 – 1.4 W/(m²·K) | ISO 10077-2 / NFRC 100 |
| Air Infiltration Rate | 2.1 m³/(h·m) @ 100 Pa | 0.8 m³/(h·m) @ 100 Pa | 0.08 m³/(h·m) (Class 4) | ASTM E283 / EN 12207 |
| Static Water Resistance | 150 Pa (Intermittent leaks) | 350 Pa (Moderate rain) | 900 Pa (Severe Cyclone) | ASTM E331 / EN 12208 |
| Structural Wind-Load Rating | 1200 Pa Serviceability | 2400 Pa Serviceability | 4500 Pa (AS2047 N6 Grade) | ASTM E330 / AS 4055 |
| Acoustic Attenuation (STC / Rw) | 22 – 25 dB | 32 – 35 dB | 42 – 47 dB (Tri-Glaze Acoustic) | ASTM E90 / ISO 717-1 |
| Hardware Cycle Durability | 10,000 Opening Cycles | 25,000 Opening Cycles | 100,000 Continuous Cycles | EN 13126-8 / AAMA 901 |
Strategic Procurement Intelligence
Future Purchasing Trends in Global Fenestration (2025–2030)
International real estate developers, commercial contractors, and institutional importers face evolving regulatory climates. Understanding these four macro trends prevents project obsolescence and delivers high resale value.
Trend 01
Embodied Carbon & Circular Billets
Global ESG initiatives are mandating low-carbon aluminium extrusions manufactured using hydroelectric power rather than coal-fired smelters. Our OEM capabilities support documented carbon footprints below 4.0 kg CO₂e/kg Al, enabling compliance with LEED v4.1 and BREEAM certifications.
Trend 02
Integrated Hidden-Sash Minimal Sightlines
Contemporary architecture demands maximum glass-to-frame ratios. Our ODM R&D team engineers concealed-sash swing windows where the outer vent frame disappears behind the outer perimeter jamb, delivering uninterrupted external monolithic glass facades with uncompromised drainage.
Trend 03
Smart Mechatronic Micro-Ventilation
Procurement for luxury villas and high-tier hotels increasingly demands integrated 24V concealed chain-drives and motorized limiters linked directly to building management systems (BMS). DERCHI swing systems feature internal conduit channels for concealed automation wiring.
Trend 04
Anti-Corrosion C5-M Coastal Finishes
With coastal urbanization across Africa, the Middle East, and Australasia, standard powder coatings blister within 36 months. Future procurement demands architectural Qualicoat Class 2 Superdurable or 3-coat AAMA 2605 fluoropolymer (PVDF) finishes that guarantee 30-year colour fidelity.

Professional Procurement FAQ
Frequently Asked Questions by Commercial Buyers
Straightforward, technical answers regarding tooling, quality validation, multi-point hardware options, and international maritime container shipping.
What are the minimum order quantities (MOQ) and lead times for custom OEM/ODM extrusions? +
For existing system dies (such as our 50mm, 65mm, 75mm, and 85mm thermal-break series), there is no strict MOQ; we support boutique villa schedules starting from 30 m². For bespoke ODM dies requiring custom cross-sections, new extrusion tooling costs are typically waived once order volume hits 5 to 10 metric tons. Tooling fabrication and extrusion sample trials take 15 working days; full production cycles average 25–35 days depending on glass specifications.
How do you guarantee air and water tightness under tropical cyclone conditions? +
Our swing windows integrate continuous corner vulcanized EPDM gaskets paired with cast aluminium corner cleats injected with two-component German polyurethane adhesive. This prevents diagonal sash sagging while creating a totally sealed, pressurized drainage pathway. Systems tested under Australian AS2047 N6 cyclonic standards withstand over 4,500 Pa wind pressures and 900 Pa driving rain without trace leakage.
Which hardware brands are integrated, and can we specify custom hardware? +
Standard configurations utilize European euro-groove standards. We collaborate directly as authorized tier-one partners with German Siegenia, Roto Frank, Hoppe, and CMECH. We offer multi-point locking with hardened steel mushroom pins, concealed friction hinges capable of supporting up to 130 kg sash loads, anti-mishandling mechanisms, and heavy-duty child safety restrictor stays. Client-specified hardware can be factory-prepped via CNC router templates.
What marine-grade surface finishes do you apply for harsh coastal environments? +
For coastal markets such as Lagos, Mombasa, Sydney, or the Caribbean, we apply AkzoNobel or PPG architectural fluoropolymer PVDF coatings (exceeding AAMA 2605 requirements with 3-coat/2-bake processes) or 25-micron hard-anodized finishes. These coatings resist salt-spray corrosion beyond 4,000 hours in continuous ASTM B117 salt fog testing without blistering, chalking, or colour shift.
How are large glass swing assemblies packaged to prevent sea freight damage? +
Every unit is protected with peelable protective film over profiles, wrapped in 5mm pearl cotton shock-absorbing foam, and sealed with heavy-gauge waterproof plastic sheeting. Units are then secured in fully enclosed, fumigated solid marine plywood crates reinforced with galvanized steel corner angles. We engineer container loading diagrams utilizing 3D packing software to maximize container cube volume while guaranteeing zero transit movement on ocean voyages.
Can your engineering team support shop drawings and BIM integration for architectural submittals? +
Yes. Our in-house technical department of over 30 structural engineers delivers complete architectural shop drawings in AutoCAD (.dwg) and 3D parametric Revit/BIM (.rfa) formats. We provide structural wind load deflection calculations, glass thermal stress analyses, and anchor connection details for consultant approvals prior to cutting raw aluminium billets.
What documentation is provided to clear customs under SONCAP, KEBS, or Australian standards? +
We provide comprehensive factory compliance packages including third-party laboratory test reports (CE, AS2047, ISO9001), Certificate of Origin (Form E, Form M, or standard CO), detailed packing lists with net/gross weights and cubic metres, commercial invoices, and bill of lading. For African markets, we support pre-shipment inspections (SGS, Intertek, or CCIC) necessary for Nigeria (SONCAP) and Kenya (KEBS PVoC).
What is your standard warranty and after-sales spare parts policy? +
We provide a 10-year comprehensive structural warranty on all thermal break aluminium frame extrusions and a 5-year replacement warranty on operational hardware (hinges, multi-point lock mechanisms, and handles). Every full container shipment includes a 2–3% complimentary surplus parts kit (EPDM gaskets, corner keys, strike plates, and screw caps) ensuring immediate on-site remediation during installation.
