With increasingly stringent environmental requirements, direct exhaust skylights are no longer recognized or accepted by environmental protection authorities. This necessitates continuous technological innovation in products to meet practical needs. Skylights that utilize carbon adsorption for dust collection and purification before emission represent the future mainstream trend. It is believed that future skylights will become more intelligent and environmentally friendly.

The layout of ventilation skylights on roofs is divided into horizontal and vertical types, which are professionally referred to as ridge skylights and slope skylights. Ventilation methods include natural open type and electric operable type. The natural open type, commonly known as direct exhaust skylights, discharges indoor heat, foul air, smoke, and dust directly outdoors through the skylight opening.
