This no-glue window film provides excellent heat insulation, keeping your home cool in summer and warm in winter, reducing energy costs. It effectively blocks harmful UV rays, protecting your skin, eyes, and furniture from sun damage, and reducing glare for comfortable reading and preventing furniture fading. The film offers daytime privacy, allowing you to see out while preventing others from seeing in, creating a mirror-like effect. Its static cling design ensures easy, glue-free application and removal, making it relocatable and reusable. For best results, ensure the glass is clean, use plenty of soapy water, and follow the installation guide carefully to avoid bubbles and scratches. The transparent protective film can be used to protect the window film during smoothing.
