Rabbitgoo Privacy Window Film, 18×79-Inch

Sure, privacy window film can keep nosy neighbors from peering in through otherwise uncovered windows.

But Vicki Liston, writer, producer and narrator of award-winning home improvement and DIY show called “On The Fly…DIY” says window film can do that and more.

“While it provides the obvious — blocking outside, wandering eyes from seeing every detail inside your home — privacy window film delivers more advantages than you might think,” she says. “It can stop harmful UV rays from damaging your furniture, flooring and décor. It can save on cooling costs in the summer by reflecting both sunlight and solar heat.”

She says that window film can have health benefits as well as aesthetic advantages.

“For households with allergies and asthma, films can serve as a welcome alternative to dust-attracting curtains and blinds (imagine never having to wash curtains or wipe off blinds again!),” she says. “If you love a more minimalistic look or you can’t bear the thought of impeding the view of your gorgeous window frames, you can still block out the rest of the world while allowing in natural light and keeping those frames free from obstruction.”

Privacy film can be invaluable to renters who want to enjoy the advantages without worrying about damaging or altering the windows in a rental home. Most window film is not only easy to install but also simple to remove, so renters can beautify and protect any glass surface with no worry of backlash from their landlords.

It is important to note that there are several different types of window film, and not all of them provide every possible benefit. Determining what features are most important to you and how you plan to use it will help you find the best privacy film for your home.

“For those ‘privacy only’ concerns, opt for an opaque, a decorative pattern, or a mirrored film,” says Liston. “Opaques and decorative patterns will stop the gaze of your nosy neighbors but they will also stop your gaze as well. A mirrored film is highly reflective and allows you to take in the view outside but your privacy level may wane as the sun goes down. Some types become semi-see through at night so read the label carefully on mirrored and reflective versions before you make a decision.”

Window film is quite affordable, as well. This is especially true when you compare the cost of privacy film to other types of custom window coverings, such as blinds, curtains or frosted glass.

• The location of your home should factor greatly into the type of window film you purchase. The direction that your windows face is an important consideration, as well.  For instance, if you live on a forested lot in Pennsylvania with lots of north-facing windows, you might want the film to let in in as much natural light as possible. However, if your home is in the Arizona desert or your west-facing windows take a beating every afternoon, you may hope to keep as much sunshine and heat out of your house.
• Adhesive privacy window films that activate with water offer long-lasting results. Choose these over films that require applied adhesive or static cling films with no adhesive. The former is messy and difficult to apply, while the latter simply won’t stand up to temperature changes or the passing of time.
• Prepare the window or glass surface by cleaning them thoroughly. Ammonia-or vinegar-based cleaners could damage the film, so opt for a mild soap in water instead, such as baby shampoo. Be sure to rinse the glass well with clean water before applying the film.
• Applying privacy film when the temperature outside has been at least 60 degrees Fahrenheit for several days will ensure that the bond has time to cure, providing the best adhesion results.
• Always apply privacy film to interior surfaces or the inside of windows. Privacy window films are not intended for exterior use and will not endure the elements effectively.
• No need to spend additional money on fancy, specialized tools or applicators for privacy film. A standard, clean spray bottle, and a credit card or other small, rigid piece of plastic work just as well as a squeegee, scraper, or other items that you might purchase but only use for a single application.
• A razor blade will make trimming the edges much easier, as well.
• Measure the window before cutting or applying the film. Start by measuring the inside of the frame from left to right and again from top to bottom. Add about two inches to each measurement to give yourself some wiggle room when installing the film and to allow for any potential errors.
