Nowadays, in order to achieve the purpose of firefighting smoke exhaust and ventilation, factories will install smoke vents on the roof. Leakage of the roof vents is a headache for all owners.

Why does the smoke vents leak?

1. Traditional ridge ventilator is generally waterproof by silica gel. Silica gel is a kind of chemical material, which is easy to age and crack. Once the silica gel and tape are aging, there will be hidden dangers of water leakage in the joints of the flooding plate, end joints, and sink joints of the ventilator;

2. Due to the long-term working condition of some production equipment, the equipment's vibration will also cause the silica gel crack and water will leak into from natural ventilator ;

3. The wind and snow loads in some coastal and northern areas are relatively high. If smoke ventilation is subjected to different wind directions, wind or snow loads, the ventilator plate will produce different deformations and displacements, which will cause the silica gel crack;

4. As the temperature changes in different seasons, the steel plates between the gaps will shrink and expand, and the silica gel between the gaps between the steel plates will move, which will easily cause the silica gel crack.

How to eliminate the hidden danger of water leakage?

1. The smoke vent system adopts structural waterproof technology. The structural waterproofing technology dont use silica gel and tape to seal, avoiding the hidden danger of water leakage caused by the aging and cracking of silica gel and tape.

2. The full-structure waterproof industrial ridge vent completely relies on its own structure for waterproofing, and the waterproof service life is same with the building roof outer panel.

The full-structure waterproof technology is Mcwell's patented technology. The "nail-free and glue-free waterproof structure patented technology" completely eliminates leakage hazard.
