The roof louver vent is installed on the building's roof and need to be exposed to the open air and withstand the sun and rain at all times. Therefore, low-profile ventilator needs high windproof and rainproof performance.

In the selection of roof louver vent, many customers will focus on windproof performance, especially in coastal areas which hurricanes and strong winds happen frequently, natural roof ventilation with extremely high hurricane resistance should be installed, and the center of gravity should be as low as possible. At the same time, a streamlined design is adopted to reduce the resistance of the smoke vent louvers to the hurricane. Therefore, Mcwell advices clients to choose high quality roof louver vent as much as possible, so that natural vent will be more secure.

At the same time, Mcwell do not recommend to use umbrella rain caps, because the wind resistance is too large and the height is too high, and it is not conducive to the safety of the plant if placed in strong wind areas.

In areas with strong hurricanes and typhoons, as a professional smoke vents manufacturer, Mcwell recommends the use of side-by-side ventilation skylights. Roof louver vent has light load, low height, and can have good wind resistance.
