The Side-Hung Outward-Opening Window is a type of aluminum alloy window featuring side-mounted hinges that allow it to open outward. Since the sash does not encroach upon interior living space when opened, this design is ideally suited for building apertures where optimal natural lighting, ventilation, and exterior facade aesthetics are required. By integrating thermally broken aluminum profiles, insulated glazing, sealing strips, and an outward-opening mechanism, this window system is widely applicable in fenestration projects for residential homes, villas, hotels, office buildings, and similar structures.

The Side-Hung Outward Opening Window features a flush-to-frame design on both the interior and exterior sides. When closed, the facade lines appear more streamlined and orderly, making it an ideal choice for modern residential properties and high-end commercial projects. The 110mm frame profile, paired with a 75mm visible sash width, minimizes visual bulk; this creates a more seamless transition between the window unit and the wall surface, thereby enhancing the overall aesthetic appeal of the building.
This Side-Hung Outward Opening Window employs a triple-seal structure. Multiple layers of weatherstripping—positioned on the outer, middle, and inner sides—form a continuous, airtight barrier that significantly enhances resistance against wind, dust, and rain. When equipped with EPDM composite weatherstrips, the system is particularly well-suited for use in rainy, humid, street-facing, and high-rise environments, effectively minimizing air leakage through window gaps, preventing rainwater infiltration, and reducing external noise interference.
The Side-Hung Outward Opening Window incorporates PA66GF25 nylon thermal break strips, paired with 5mm+20A+5mm insulated glass units, to effectively reduce thermal conductivity through the aluminum profiles. With a profile wall thickness of 1.8mm, the design strikes an optimal balance between structural strength and processing stability. This makes it an excellent choice for residential, hotel, and office building projects located in regions characterized by cold winters and hot summers, helping to improve indoor temperature stability and overall living comfort.
The exposed drainage design allows rainwater to be rapidly channeled out through dedicated drainage channels within the window frame, thereby minimizing the risk of water accumulation at the base of the frame. The drainage path is clearly visible, making subsequent inspections and maintenance both easier and more convenient. For projects located in the rainy southern regions, coastal areas, or high-rise buildings, this structural design helps mitigate issues related to moisture ingress, water stagnation, and poor drainage during rainy weather.
The product offers flexible configuration options, supporting outward side-hung, top-hung (awning), or combined side-hung/top-hung opening modes. Clients can select the specific opening style based on the building's window aperture dimensions, ventilation requirements, and user preferences. Available color options include CDG Grey and Champagne Gold, designed to complement the exterior aesthetics of modern residences, villas, and commercial developments. HEKIN provides comprehensive project-specific production support, tailoring solutions to meet precise project dimensions, glass specifications, and hardware requirements.
