PURPOSE: A window screen system with improved heat insulation using an expandable insulating material is provided to improve heating and cooling efficiency by effectively cutting off the transfer of heat. CONSTITUTION: A window screen system with improved heat insulation using an expandable insulating material comprises a main body portion(110), connection portions(120), a screen portion(130), a screen movement control unit(140), and a screen rotation control unit(150). The main body portion is fixed to the inner top end of a window and has a rail. The connection portions are coupled to the rail of the main body portion to be slidable. The screen portion is composed of multiple insulation screens manufactured using an expandable insulating material and screens the window. The screen movement control unit moves the connection portions to fold or unfold the screen portion. The screen rotation control unit screens the window by rotating the connection portions. |
