The electric roller shutter window is installed on the outside of the window to directly block the heat of the sun outside the window.
The energy saving effect of the sunshade is very obvious. When the roller blind is lowered, it can block almost all the solar radiation and minimize the amount of solar energy entering the window.
It is also possible to appropriately open the roller blind to take away the heat of the roller blind by using natural ventilation, and reduce the heat on the roller blind to be transmitted to the room.
Use public places or residences such as commercial facades, garages, shopping malls, hospitals, factories and mines. In particular, the door opening is large, and it is convenient and quick to open the place where the ground door body is inconvenient. Such as for garage doors, mall fire shutter doors, garage doors.
