 Waterproof Method:

This smoke lift continuous rooflight is a holistic waterproof structure, i.e. it relies on its own structure for waterproofing. It does not use silica gel or adhesive tape to fill seams or to stop leakage, which avoids water leakage hazard caused by aging and cracking of silica gel and adhesive tape. Service life of the waterproof structure is the same as that of building roof panel.
