Does window film actually work? While glass windows alone only block 40 percent of harmful UV rays, some window films can block up to 99.9 percent. Solar films also regulate indoor temperatures, so rooms stay cooler in summer and warmer in winter. This in turn can improve the energy efficiency of the home and help save money.
Can you see through window film at night? At night, the window film will block about 95% of the light to give you a high level of privacy. During daylight hours, any ambient light will reflect the mirror film’s surface, making it impossible to see inside. Yet, at the same time, you will be able to see outside.
How long does window privacy film last? The lifespan of window film depends greatly on its quality and the materials used in its manufacture. Most window films last somewhere between 10 to 20 years. However, this time can be longer or shorter depending on the amount of stress put on the film.
How much does bulletproof window film cost? In general, security film will cost anywhere from $8-$18 per square foot. This price includes materials, labor, shipping, and travel for the professionals completing your installation.
