What is the patented technology of full-structure waterproofing of roof natural ventilator?

The patented technology of full-structure waterproofing is the collective name of several patented technologies of Sichuan Maikewei Technology Co., Ltd. The patented technology of full-structure waterproofing uses special fittings to fasten all joints such as the drainage trough of the roof natural ventilator, the longitudinal joints of the flashing board, the joints between the longitudinal flashing board and the transverse flashing board, and the joints of the flashing board, instead of using silica gel and adhesive tape to caulk and stop leakage. Special fittings and fasteners are integrally formed by molds to ensure the waterproof life is the same as that of the outer panel of the building roof.
