After install the electric actuator in the roof ridge ventilator, then rainproof board needs to be installed. The rain plate of the smoke vent rooflight is installed on the two inclined beams of the frame of the roof ridge vent. In fact, in general, it is relatively simple to install the rainproof plate of ridge ventilator. It only needs to connect the perforated light-transmitting FRP plate and the two inclined beams of the frame with screws. When installi weatherproof panels for roof smoke vent, we must grasp the distance between weatherproof panels, and minimize the gap between weatherproof panels as much as possible. Many manufacturers of ventilated buildings have installed packages and have rich experience. When they prevent the problem of water leakage between the gaps of the weatherproof board, they usually use rainproof glue to adjust the contact part of the rainproof board. The two parts of the rainproof board The ends are sealed with steel plates.

The smoke vent rooflight is installed on the roof of the industrial plant, so its rainproof performance is particularly important. If the rainproof effect is not good, it will easily cause the mechanical social damage inside the industrial plant and workshop, and the goods will be wet. Therefore, the rainproof performance is one of the important signs to test the ridge ventilator's performance.
