Does window film cause seal failure?
Our product has never been shown to be the cause of seal failure. Manufacturers continuously analyzed how window films affect temperature and pressure within the airspace of an insulating glass unit. Results indicate that on a clear insulating unit, even our most popular residential film 35 neutral only increases the summertime airspace temperature by no more than 22 degrees, a pressure increase of only .55psi (pounds per square inch). Put into perspective, most manufacturers of insulating glass units design their products to withstand a pressure change of 3.30 psi, over six times the film’s potential pressure increase!
