As an important part of the roofing system, electric smoke vents' performance is also a concern for business owners. Business owners mainly judge whether the smoke exhaust ventilator is good or not from the following performance.

1. Structural safety:

The window or frame structure of the electric smoke vents of the steel structure factory building shall meet the relevant climatic conditions such as wind load, snow load, and seismic level of the project location.

2. Ventilation and smoke exhaust performance:

The geometric size and internal structure of automatic opening vent must be reasonable to ensure a large effective opening rate, a small ventilation and smoke exhaust resistance coefficient, and a better ventilation and smoke exhaust performance.

3. Rainproof performance:

"Nail-free and glue-free waterproofing structure" is the recommended waterproof method for smoke vent skylights of industrial plants in the market. The sash profile of the automatic opening vent should have a seamless internal drainage structure, and the waterproof performance should be long-term and reliable.

4. Daylighting performance:

Electric roof smoke vent's rain-proof panels generally use daylighting panels with better lighting performance. FRP daylighting board is short for glass fiber reinforced methylene dicarboxylic acid polyester daylighting board, which is composed of three raw materials: resin, glass fiber and anti-aging film. The light transmittance of the FRP daylighting board is 0-85%. Because a certain proportion of glass fiber is added to the polyester, the light will diffusely scatter when it passes through, and it will not leave a light band on the ground or produce glare. So it can provide a good working environment.
