Among the advantages and disadvantages of natural roof ventilation, the main advantages are the diversification of ridge ventilator, control methods, and the selection of lighting materials. The main disadvantages of steel roof ridge vent is poor ventilation. The traditional natural ventilator use nailing and glueing methods can easily lead to rain leakage in the plant.
1. Advantages of natural roof ventilation in steel structure workshops:

1. Diversified types

Smoke vent in steel structure workshops can be divided into linear natural vent, triangular electric smoke ventilator, and arched continuous rooflight according to their appearance.

2. Flexible opening and closing control method

There are three ways to control the opening and closing of the natural ventilator, which are divided into: Common control method: Manually control the opening and closing in groups at the same time, with the function of fire protection linkage.

Intelligent control mode: control the roof vents to open and close at the same time in groups. The opening and closing of the sunroof has the function of angle setting, opening and closing mode setting, sunroof opening and closing status display and fault alarm display, various sensor automatic control functions, and fire linkage function. Intelligent network control mode: with intelligent control function, remote centralized control can be realized through the local area network, and the fire protection linkage function is provided.

3. Selection of lighting materials

The significance of the daylighting natural ventilator is to use skylight lighting materials to introduce the sunlight from the outside and windows into the deep inside of the building through reflection, so as to achieve the purpose of improving the overall brightness of the inside of the workshop. The correct selection of lighting materials directly affects the lighting effect of electric lighting and smoke exhaust skylights. The common lighting materials for skylights now mainly include laminated glass, hollow safety glass, sunlight panels, FRP lighting panels, and FRP lighting panels are economical and durable. The advantage of not easy to turn yellow.
