As a premier B2B manufacturer based in Foshan, China, Window Wurx Industry Co., Ltd. custom-engineers high-performance aluminum louver windows, sliding doors, and structural curtain walls tailored to international architectural standards including AS2047, CE, and NFRC.
An in-depth whitepaper on thermodynamic fluid movement, structural extrusion integrity, weatherproofing seals, and automated drive systems in modern louver fenestration.
Unlike conventional sliding or casement windows that obstruct up to 50% of the rough opening, aluminum jalousie windows yield a 100% net-free ventilation area. By manipulating louver blade tilt angles from 0° to 90°, architects leverage the Venturi effect to accelerate cross-breeze speeds in tropical and sub-tropical microclimates. Our OEM extrusions maintain a high discharge coefficient ($C_d \approx 0.65$), minimizing static air resistance and drastically lowering HVAC power consumption in high-density commercial developments.
All window jambs, sills, and blade operator channels are engineered from primary-grade 6063-T5 or T6 heat-treated aluminum alloy. With nominal wall thicknesses ranging from 1.4mm to 2.5mm, these extrusions provide a tensile strength exceeding 205 MPa and a yield strength over 170 MPa. Surface treatments include Qualicoat Class 2 Architectural Powder Coating, 25µm anodization for marine environments, and PVDF coatings resistant to high-UV degradation and salt-spray corrosion (ASTM B117 tested for 3,000 hours).
Our ODM hardware ecosystem accommodates both heavy-duty manual crank gearboxes and smart motorized actuators. Integrated linear or tubular drive motors operate at 24V DC with 600N to 1500N push/pull force capacities. System operators interface directly with Building Management Systems (BMS) via Modbus, KNX, or IoT protocols—automatically closing louvers upon sensing high wind speeds, heavy rainfall, or indoor CO2 spikes, ensuring structural security and optimal indoor air quality (IAQ).
Historically vulnerable to water infiltration, modern engineering resolves sealing flaws through pressure-equalized drainage tracks and continuous vulcanized EPDM double-lip compression gaskets. Each louver blade edge clips firmly into UV-stabilized nylon blade retaining cups. Under rigorous AS2047 and ASTM E331 testing, our high-wind jalousie assemblies withstand water penetration at cyclic pressure dynamics exceeding 600 Pa and wind loads reaching structural limits of 6000 Pa (Serviceability Limit State).
To mitigate thermal bridging in extreme cold or hot climate zones, our OEM ODM catalog features Polyamide 66 (PA66 GF25) thermal break barriers within the perimeter frame extrusions. Combined with double-glazed insulating glass blades (5mm Low-E + 9A + 5mm Tempered) or hollow aerofoil extruded aluminum blades, system overall system U-factors drop as low as 1.8 W/m²·K, offering acoustic dampening up to STC 38 dB.

Key technological trajectories shaping how global real estate developers, contractors, and fenestration distributors procure custom aluminum windows.
Future green building standards (LEED v4.1, BREEAM) increasingly penalize fully static glass facades. Automated jalousie windows integrated into smart HVAC grids dynamically adjust louver angles based on sun-tracking algorithms (solar shading) and temperature differential sensors. Procurement demand is shifting rapidly toward fenestration suppliers capable of embedding low-voltage actuators, encoder limit switches, and weatherproof wiring harnesses directly into factory-shipped window assemblies.
European and North American procurement teams now require Environmental Product Declarations (EPD) detailing embodied carbon metrics. Leading manufacturers utilize hydro-powered aluminum smelters and post-consumer recycled aluminum alloys (up to 75% recycled content) to yield profiles with carbon footprints below $4.0\text{ kg CO}_2\text{e/kg Al}$. Sourcing partners who prioritize green smelting gain immediate advantage in public sector and tier-1 commercial tenders.
As global climate instability amplifies storm severity, building envelope specifications in coastal regions (Florida Metro Dade, Australian Cyclonic Zones, Caribbean, Pacific Islands) mandate rigorous impact resistance. Future-proof louver windows feature high-tensile stainless steel security bars embedded behind the glass blades or hurricane-rated laminated glass blades capable of passing large missile impact tests (TAS 201/203 & AS/NZS 1170.2 standards).
Established in 1993 in Foshan—China's global capital for aluminum manufacturing—Window Wurx provides end-to-end OEM and ODM capabilities for high-end residential villas, commercial towers, and hotel developments.

Our window and door systems are fully tested and certified for key global jurisdictions. For the Australian and New Zealand markets, our products comply with AS2047 (Windows and External Glazed Doors in Buildings) and AS1288 (Glass in Buildings), verified for structural wind load, air infiltration, and water penetration resistance. For European projects, we carry CE certification (EN 14351-1). Additionally, our thermal break glass louver lines meet NFRC guidelines for U-Factor and Solar Heat Gain Coefficient (SHGC) ratings required in North America.
We maintain highly flexible manufacturing schedules to serve both bespoke luxury villa projects and large commercial developments. Our typical MOQ is 50 square meters for standard profile finishes (e.g., Matt Black, Anodized Silver, Architectural White). For custom extrusion dies or unique RAL powder coat color matching, MOQ is negotiated based on profile weight. Standard production lead time is 25 to 35 business days following formal shop drawing sign-off and deposit confirmation.
Yes. By utilizing thermal break polyamide insulating strips (PA66 GF25) to join separate inner and outer aluminum profile halves, we can manufacture true dual-tone window frames. This allows you to specify an exterior powder coating or anodized finish that matches the outer building facade (such as dark bronze or metallic grey), while specifying an interior finish that perfectly coordinates with indoor cabinetry and trim (such as warm timber woodgrain or soft off-white).
Our heavy-duty jalousie series features reinforced 6063-T6 aluminum jambs, heavy-gauge stainless steel blade drive bars, and engineered blade retention clips. Under certified laboratory air-water-structural pressure testing (ASTM E330 / AS4420), our high-span louver units achieved an Ultimate Limit State (ULS) wind pressure rating of 6000 Pa. For extreme cyclone zones, we offer continuous key-lock blade clamps and impact-resistant 13.52mm SGP laminated glass louver blades.
We supply a comprehensive spectrum of blade materials and geometries:
• Tempered Glass Blades: 6mm to 10mm clear, low-iron, frosted, tinted (grey/bronze), or Low-E coated safety glass with polished arrissed edges.
• Extruded Aluminum Aerofoil Blades: Hollow or solid aluminum sunblade extrusions for complete privacy, superior sun shading, and maximum security.
• Timber / Composite Blades: Weather-treated natural timber or low-maintenance WPC blades for architectural accent facades.
