Roof vents can discharge the dirty and harmful gases in the factory in time and effectively, which not only improves the working efficiency of employees, but also contributes to their health. This kind of roof vent is natural ventilation. It uses the heat pressure formed by the temperature difference between indoor and outdoor and the wind caused by wind to realize natural ventilation,

without external power, energy saving and environmental protection. As smoke vent manufacturer, Mcwell will introduce how to design the ventilation skylight drainage.

How to drain of the roof vents

The installation of natural lighting and ventilation can purify the indoor air to a certain extent, but if the waterproofing and drainage are not handled well, in the event of rainy weather, rain leakage in the house will seriously affect production and life.

The slope of the roof is basically between 10°-60°, and the roof over 10° is called a sloping roof. It is generally considered that 30° is a slope, and the roof top surface of this slope is less stressed and the roof drains water. There is an international standard for the drainage of roof smoke ventilators: the drainage performance mainly relies on aluminum alloy drainage panels, and special waterproof coatings are made on the surface of the drainage panels to ensure long-term use of roof vents in various climatic conditions. In order to ensure the quality of the waterproof coating, the owner can ask the merchant to do a smoke test and an ultraviolet test when purchasing.

Drainage design of natural roof ventilation

There is a common method for the drainage design of ventilation skylights: design a concealed drainage channel. This special drainage system structure can effectively guide rainwater from the roof at the top of the window to the roof tile at the bottom of the window.
