AtmosFX Window Projection Material is made from a woven fabric that provides excellent contrast and light diffusion. It’s easy to set up, store and reuse. Compared to other solutions, this material has excellent light management, better image reproduction and reduced hot-spotting. You can also create a more uniform surface to project onto, resulting in more realistic and believable digital decorations in your window. This material also features six grommets for additional set up options. For fast and easy set up, use the included peel-and-stick hang tags.
