The parallel opening system is used in certain projects to enhance ventilation and safety. The sash moves outward as a single unit in a parallel motion (perpendicular to the façade) by up to 200 mm. This type of opening is particularly suitable for high-rise buildings where wind pressure and safety are critical considerations. The parallel movement ensures that the sash remains securely guided throughout the entire opening process, preventing any swinging or uncontrolled motion. Additionally, the system allows for effective natural ventilation without compromising the building's overall aesthetic or structural integrity. When closed, the sash seals tightly against the frame, providing excellent air and water tightness comparable to traditional casement windows.
