The Open Outward Window is an aluminum alloy window type designed to open toward the exterior. Its sash is connected to the frame via side-mounted hardware, ensuring that—when opened—it does not encroach upon the interior living space. This design is well-suited for window openings in a wide range of buildings, including private residences, villas, apartments, hotels, and office complexes. By incorporating thermal-break aluminum profiles, insulated glazing, sealing strips, and an outward-opening mechanism, it effectively meets the diverse requirements of architectural fenestration projects regarding natural lighting, ventilation, aesthetic facade uniformity, and overall project compatibility.

The Open Outward Window features a 117mm frame structure, with load-bearing profiles reaching a thickness of up to 3.0mm and profile wall thicknesses ranging from 1.4mm to 3.0mm. This thicker profile configuration enhances the window's load-bearing capacity, making it ideal for high-rise residential buildings, villas, and projects involving large window openings; it also minimizes the risk of loosening or deformation after prolonged use.
This Open Outward Window utilizes PA66GF25 nylon thermal break strips, paired with 5mm + 27A + 5mm insulated glass, to effectively reduce thermal conductivity through the aluminum profiles. The 27mm air gap—larger than that found in standard insulated glass configurations—is particularly well-suited for energy-efficient window and door projects, helping to stabilize indoor temperatures and making it an excellent choice for regions characterized by cold winters and hot summers.
The Open Outward Window supports various opening modes: outward casement, top-hung, or a combination of both; for select projects, an electric opening mechanism is also available. The outward-opening structure maximizes the ventilation angle without encroaching upon interior space, making it suitable for windows in living rooms, bedrooms, studies, and office areas. The top-hung mode facilitates moderate air exchange while enhancing convenience for daily use.
Featuring multi-chamber thermal break strips and a multi-layer sealing structure—complemented by EPDM composite gaskets—the Open Outward Window delivers superior performance in wind resistance, dust prevention, rain protection, and sound insulation. For projects involving high-rise buildings, street-facing properties, coastal locations, or rainy regions, this robust sealing configuration effectively prevents air leakage through window gaps, water infiltration, and external noise interference.
The 117mm frame, paired with a 75mm visible sash width, creates clean and distinct lines that complement the facades of both modern residential and commercial buildings. A variety of color options—including CDG Grey, Coffee Brown, and Champagne Gold—are available to suit diverse project styles. HEHEJIAN offers customized project-based manufacturing, tailoring production to specific window opening dimensions, glass specifications, hardware configurations, and surface finishes.
High-rise residential buildings impose stringent requirements on the wind-load resistance, airtightness, and safety of exterior windows. This Open-Outward Window system is suitable for use in living rooms, bedrooms, studies, and similar areas. Featuring 3.0mm load-bearing profiles paired with CMECH hardware, the system enhances the operational stability of the window sash; furthermore, the outward-opening mechanism minimizes interference with interior furniture arrangements.
Villa living rooms prioritize natural lighting, scenic views, and aesthetic facade impact. This Open-Outward Window system is ideal for large window openings, panoramic viewing windows, and spaces facing courtyards. The 117mm frame profile—combined with insulated glazing—helps improve thermal insulation and acoustic performance, ensuring that the villa's interior environment meets the high visual and comfort standards expected of luxury developments.
Scenic apartments demand superior views, ventilation, and sound insulation. This product is well-suited for high-rise residential units situated along rivers, lakes, coastlines, or within urban landscapes. The 5mm + 27A + 5mm insulated glazing configuration effectively blocks external noise, while the slim 75mm visible sash profile minimizes visual obstruction from the frame, allowing for more expansive natural lighting within the interior space.
Hotel suites place high demands on the soundproofing, thermal insulation, airtightness, and ease of maintenance of their windows and doors. This Open-Outward Window system is suitable for guest room windows, executive suites, and corridor lighting windows. The availability of multiple opening modes facilitates effective ventilation management, while the use of CMECH hardware ensures ease of maintenance—a critical factor for large-scale hospitality projects.
Office buildings require windows and doors that strike a balance between natural lighting, ventilation, energy efficiency, and visual consistency across the facade. This product is suitable for windows in private offices, conference rooms, reception areas, and public corridors. The combination of side-hung and top-hung (awning) opening modes allows for flexible adaptation to varying ventilation requirements, while the thermal-break aluminum structure paired with insulated glazing enhances the overall comfort and usability of the commercial workspace.
