Roof smoke vent plays an important role in plant lighting, ventilation and smoke exhaust. There are many different types: linear natural ventilator, triangular smoke vent, arched continuous rooflight. Different types of roof smoke vent has different characteristics.

Electric smoke vents are mainly composed of window frames, window sashes, window components, electric window openers, etc. The window frames use special aluminum alloy profiles, and the window sashes use polycarbonate lighting panels (sunlight panels) or glass fiber polyester lighting panels (FRP daylighting board) and other daylighting materials, the window components are cold-formed by color-coated steel plate, and filled with polyester foam material for heat preservation.

The arched continuous rooflight is composed of frame, window sash, special aluminum profile, daylighting material and transmission system. The frame is cold-formed with galvanized sheet. The thermal insulation rubber strip is installed on the window frame to form a double seal with the rubber strip installed on the window sash. The window sash is composed of window sash profile (broken bridge aluminum profile or aluminum alloy profile) and daylighting material (sunlight board or FRP daylighting board). EPDM rubber strips are installed at the joints of special aluminum profiles and lighting materials. It has high-quality water resistance and airtightness.

The side-opening electric daylighting natural ventilator is mainly composed of a frame, a window sash and a transmission system. The frame is composed of special galvanized sheet profiles, and the window sash is composed of window sash profiles (broken bridge aluminum profiles or aluminum alloy profiles) and lighting materials (sunlight boards or FRP lighting boards).
