Traditional fully open skylights are rarely used in modern residential designs due to their various drawbacks. Instead, a semi-open design is adopted: using partial glass or louvered blinds as shading to achieve sun protection and thermal insulation effects.
There are three types of ventilation skylights: ceiling-mounted, window-mounted, and wall-mounted, available in materials such as metal and plastic. Regardless of the type of ventilator, proper use is essential for effective exhaust and ventilation. Correct maintenance methods can help maintain the ventilator well and extend its service life. Below are the correct usage and maintenance guidelines for ventilation skylights.

Electric open-close ventilation skylights are based on natural open ventilation skylights with the addition of an electric system and open-close flap panels. When ventilation, air exchange, smoke exhaust, or dust removal are needed, the electric open-close flap panels are opened. When ventilation and smoke exhaust are not required, the electric flap panels remain closed to prevent indoor and outdoor air convection.
