Horizontal roller shutter aluminum window / roll up storm shutters

The window is the main channel for daytime lighting in the room, which eliminates the energy needed for the lighting of the lamp, and is also the path of human contact with nature. At the same time, it loses the valuable heat in the room to the outside. In summer, the excess heat is transferred to the room, so that people need to use a lot of electricity (air conditioning, etc.) to balance the indoor temperature.

A window shutter installed in front of the window or door can make the heat loss through the window down more than 40%..
