Safety Window Films are designed to protect people and property from flying shards of glass. Optitune combines a highly reflective outside layer for high solar heat rejection with a lower reflectance color layer for your inside view. Often used for daytime privacy, this window film allows you to have a glare-free internal view, while people outside see only what is reflected off the film. It is 10-mil thick and features 99% UV blocking, pressure-sensitive adhesive and a durable scratch-resistant coating.
