Because of Mcwell's full-structure waterproof technology, the installation and use of roof vents has greatly improved, and has substantially improved the effective waterproof life of the natural ventilator.

There are three characteristics of the waterproof technology of the natural vent.

1. Patent rights

The structural waterproofing technology was invented by Mcwell, and the patents of Mcwell are over 70.

2. The appearance of structural waterproof technology

The waterproof structure avoids the hidden danger of water leakage caused by the aging of silica gel. At the same time, the technology has tended to look beautiful.

3. Structural waterproof integrated buckle

The professional fasteners used in the structural waterproofing technology have greatly changed the problem of the high dependence of the traditional silica gel on the installation workers, making the waterproof reliability of the roof vents have a qualitative leap.
