Factory-direct structural architectural elements engineered for extreme weather resistance, acoustic dampening, and high thermal performance.
In contemporary architectural design, the roof fenestration segment demands the absolute highest levels of structural integrity, air-tightness, and thermal regulation. Situated in Foshan, Guangdong—the world's premier cluster for architectural aluminum extrusion—Window Wurx Industry Co., Ltd. has spearheaded advanced fenestration manufacturing since 1993. Transitioning attic spaces into light-filled, thermally optimized living environments requires roof windows that withstand severe environmental stresses, including intense UV exposure, thermal shock, hail impacts, and torrential rain.
Operating out of a state-of-the-art 20,000 square meter production facility equipped with 3 fully automated CNC fabrication lines, Window Wurx pairs raw material rigor with sophisticated European jointing techniques. Unlike standard vertical windows, roof windows are installed at inclines ranging from 15° to 85°, exposing frames to standing water pressure and concentrated solar radiation. Our architectural roof window systems incorporate high-tensile 6063-T6 aluminum extrusions, multi-chambered Polyamide (PA66GF25) thermal breaks, and continuous EPDM weather-stripping to guarantee zero water penetration under dynamic wind pressures exceeding 4500 Pa.
As global building energy codes tighten—such as the European Union's Energy Performance of Buildings Directive (EPBD) and Australia's National Construction Code (NCC)—sourcing certified high-gain roof glazing systems from verified OEM suppliers has become critical for commercial developers, architectural firms, and regional distributors. Window Wurx delivers fully customizable OEM/ODM roof window solutions certified under CE (EN 14351-1) standards and rigorously tested to meet Australia’s stringent AS2047 performance metrics.
The global market for aluminum roof windows and attic skylight systems is undergoing a monumental shift driven by carbon-neutral building targets, smart home automation, and prefabricated building modularity. International procurement managers must evaluate several macro trends when establishing supply chain agreements with Chinese factories:

The roof fenestration industry has moved far beyond simple acrylic domes and primitive manual skylights. Modern roof window engineering focuses on maximizing daylighting ratios while providing active ventilation and total weather security. Key technological evolutions currently driving product development include:
Engineers at Window Wurx have developed dual-action opening mechanisms. The Top-Hung configuration allows the sash to pivot outward up to 45°, offering unobstructed views and maximizing head clearance without intruding into the attic space. Conversely, the Center-Pivot mechanism rotates 180° on heavy-duty stainless steel friction hinges, enabling easy exterior glass cleaning from within the room—a vital feature for multi-story residential and hotel projects.
Raw aluminum possesses high thermal conductivity (approx. 200 W/mK). To counteract energy loss, our factories integrate 24mm to 34mm multi-chambered polyamide (PA66GF25 reinforced with 25% glass fiber) thermal barriers between outer and inner extrusion profiles. This structural separation interrupts heat conduction pathways, effectively preventing interior frame condensation during winter while reflecting solar heat during summer months.
Because roof windows face skyward, impact resistance and solar radiation control are paramount. Standard Window Wurx roof windows utilize toughened Low-E outer panes paired with laminated safety inner glass (e.g., 6mm Toughened Low-E + 12Ar + 4mm+0.76PVB+4mm Laminated Clear). In the event of extreme hail impact, the outer pane resists shattering; if broken, the laminated inner pane holds glass fragments intact, eliminating falling debris hazards to occupants below.
One of the biggest concerns for overseas importers sourcing glass products from China is long-transit freight damage. Window Wurx has engineered a specialized 5-layer export packaging protocol to guarantee zero-damage container delivery:
