Heat control and energy saving: the household window film reflects 80% infrared rays, reducing the heat transmitted through the window glass. A quick and economical way to reject direct sunlight and save refrigeration cost. Caution: Do not stick the film on the double-glazed window exposed to the sun for a long time. Ultraviolet protection and glare reduction: blocking up to 83% of ultraviolet rays, this sunscreen window film helps prevent floors, furniture, curtains and fabrics from fading. 24% VLT can effectively reduce glare, let some visible light enter, and create a more comfortable and safer indoor environment for you. Daytime privacy protection: This one-way privacy window film creates a mirror-like appearance by reflecting the brighter side, achieving the "visible but invisible" effect of daytime privacy, preventing external prying, and allowing natural light to enter and maintain the field of vision. When it is dark outside and the lights are on inside, this privacy effect will be reversed. Please close the curtains at night. Widely used: Our window privacy film can be applied to any flat, clean and smooth glass surface of home, kitchen, living room, bedroom, game room, garage, classroom and even your fish tank. This is a cost-effective solution for those rented houses or apartments that do not allow permanent devices to block light.
