Window Films come in many different types, some installers will put whatever they have in stock on your windows because they know you wont be able to tell the difference, or worse you wont know what happened when something goes wrong.
Residential, Safety, and Automotive films are the most used films on the market. Offering the ability to make life easier on the eyes.
Residential Films are produced to provide heat rejection and a level of privacy while still being able to see the world. Unlike blinds and curtains, Window Film stops the heat before it is in the home and prevents fading from your furniture.
Safety Films are especially appreciated in the south. They provide the same comforts of regular film, but have an added thickness that prevents break ins and are beneficial to hurricane protection. Film in general holds glass in place, Safety Film holds it together and keeps it together more then regular films.
Automotive Films main concern is keeping your car cool. Sitting in the sun all day causes your car to heat up from the sun, film will keep it cooler for when you first get in from it sitting outside. Also reducing the fading on your interior to help your car hold its resale value.
