As an important part of the roof system, the electric smoke vent system is very important to prevent rainwater leakage. Mcwell's roof smoke ventilators accept waterproof structure technology to avoid the hidden dangers of water leakage caused by the use of silica gel to seal the leaks and easily aging and cracking.

1. The joints of the sash profile and lighting material of the Mcwell's electric smoke vent system, and the connection between the sash and the window adopt triple waterproofing as follows:

1.1: the first high-quality EPDM rubber strip is used to seal the window sash profile and the lower layer of the daylighting material to ensure the air-tightness and water-tightness of the smoke vents;

1.2: The installation of integral flooding parts in the sash profiles of the heat and smoke vents fundamentally eliminates all the hidden dangers of water seepage around the sash profiles and lighting panels.

The above double waterproof structure completely eliminates the hidden danger of water leakage of the roof smoke vent window sash, and ensures that the window sash does not have any leakage problems.

1.3: A wide and thick high-quality EPDM rubber strip is added between the window frame and the window sash to further strengthen the overall air-tightness and water-tightness of the smoke vent system.
