There are several types of home glass or window tint/film, but the cost is considerable compaired to auto tint. Can auto tint be used safely on residential window glass to decrease heat, increase energy efficiency, and look nice if done right. (No bubbles, etc.)
A couple of questions here - -I'll try to answer each one.
The cost difference is really more about the amount of film being used. A car may use 20 feet of film a house 220 sq ft of film.
Auto tint is formulated for curved surfaces that get intense heat. The adhesives are different than the flat glass adhesives resins are added for the compound curves (softer). I have seen car tint on a flat glass surface -however the flat glass adhesives will be optically clear and easier to install on flat surfaces.
The cost per sq ft to install a good solar film like LLumar or VISTA may range between $5-7 a sq ft- -with a lifetime warranty . Call a local LLumar dealer http://www.llumar.com and get an estimate.
