The ECO Shade (external roller screen) prevents the intrusion of sunlight, significantly reducing the rise in indoor temperature caused by infrared and ultraviolet rays, while also preventing the fading of furniture and other items. Additionally, it has a very high solar shading effect, increasing the air conditioner's operating efficiency by about 70%, which helps reduce electricity consumption. By installing it at an appropriate distance from the window, it allows light to enter, so the indoors do not become dark. It also provides excellent privacy protection and concealment effects. Installation is very easy, and no construction work is required for the product.
