The 100 Series Side-Hinged Window utilizes a side-pivot rotating structure, allowing the sash to open horizontally up to 180 degrees and remain securely positioned at any angle, facilitating two-sided cleaning and serving as an emergency escape passage when needed. The frame is equipped with reinforced stainless steel hinge load-bearing systems and multi-point interlocking locks, combined with a triple-compression sealing design, achieving the highest national standard of Level 9 wind pressure resistance. The profiles feature wide-chamber thermally broken aluminum with injected thermal barrier technology, paired with adjustable ventilators and Low-E insulating glass, resulting in a whole-window thermal transfer coefficient as low as 1.4 W/(m²·K). Optional accessories include concealed stainless steel mesh screens, motorized opening/closing mechanisms, and rain-sensing smart modules, making it suitable for hospitals, schools, hotels, and renovation projects in older buildings where integrated demands for ventilation efficiency, safety protection, and energy performance are critical.
