Abstract

PURPOSE:To prevent water leakage indoors by sticking a water drop flowing transparent film on the inner face of the window glass of a natural light window provided on a roof and the like, and providing a water receiving part for receiving dewing water caused on the film surface and a drain port on a window frame. CONSTITUTION:An air layer 12 is provided between a glass 13 reinforced with wire-netting on the inner side and a tempered glass 11 on the outer side, so as to grant the heat insulating effect. Hereby, outdoor temperature is hardly transmitted to the inner face side of a window glass 1, and hence dewing is hardly generated. The dewing is caused on the surface of a water drop flowing transparent film 3, and the dewing water does not make water drops but a thin water layer, and the surplus produced dewing water flows down along the slope. The dewing water flows in a gutter-like water receiving part 4 through a drain piece 27, and drains outward from a drain port 5. Hereby, the production of dewing water can be restrained and also drop-in of caused dewing water into a house can be prevented.
