The popularity of window film is increasing, but many consumers still aren’t sure if window film is the right choice for them. Window film has been around since the 1970’s, and while there have been major innovations in the industry, many people may have an idea or image about films stuck in their minds that isn’t accurate.


To give consumers a clearer perspective, let’s take a closer look at five of the most common misconceptions about window film.



1. Window film is expensive.


Not true. One of the benefits of window film is that it’s much more affordable than installing new windows, but offers many of the same benefits. Professionally-installed solar control films can also significantly reduce cooling costs for homes and commercial buildings. Determining exact energy savings can be difficult because many factors contribute to energy use such as the fluctuating cost of fuel, amount of direct sun exposure, type of film installed, etc. However, typical payback in energy savings is usually 2–5 years, sometimes less.



2. Window films turn purple.


Not anymore. While this may have been true in the early 1980’s, when you commonly saw cars with windows that had a purple hue due to the discoloration of tint. The technology behind today’s automotive films is more advanced including developments in metal deposition methods, color extruded base materials, and specialty coatings. With proper installation of quality films, that type of discoloration is very rare.



3. Window film is too dark.


False. Window films come in a variety of light transmissions, allowing buyers to customize the amount of light they want for the space. Even the lightest films still block up to 99% of harmful UV rays. With today’s technology, many window films can block a significant amount of heat while still allowing in 60-70% of the visible light. With the help of a professional dealer, the buyer can decide which shade will offer the look and protection they wish to achieve.



4. Window Film is not designed to last long.


Incorrect. Window film is manufactured with longevity in mind. In fact, many window film providers offer a warranty of up to 15 years for commercial installations, and some residential and automotive window film applications come with a warranty that lasts as long as you own the house or car.



5. Window film causes glass to break.


Only in rare cases. Adding solar control film to glass increases the glass temperature, but properly chosen film installed correctly will not cause the glass to break. There are, however, some factors that can contribute to the rare case of glass breakage including the amount of external and internal shading, glass size and shape, and previous glass breakage history. Experienced dealers are able to make the proper film-to-glass recommendations, minimizing the risk of glass breakage. Many also offer limited warranty protection for properly applied installations.
