Tinted window films for houses are usually made from a micro-thin sheet of thermoplastic resin called polyethylene terephthalate (PET) that offers the strength and flexibility needed when fitting film to a window. Homeowners looking for a solution that insulates a window without blocking light from a home should investigate low-e glass vs. window film.

The most popular tint percentage for home windows is 35%. Generally, most homeowners choose a visible light transmission (VLT) between 50% and 35%, where lower numbers mean less sunlight enters the home. A 35% tint blocks over half the incoming light while still allowing plenty of natural light, which can improve energy efficiency and comfort. If privacy is a primary concern, you can opt for a tint of 50% or lower to make it more difficult for people to see inside. However, keep in mind that very dark, thick tints may offer fewer energy-efficiency benefits.

Unlike cars, there are no laws regulating window tint percentages on homes, so you can choose what you think is best. It is often a good idea to hire a professional, as they can show you samples of how different tint levels will look in your specific property, helping you make the right choice.

Window security film won’t prevent break-ins or stop your window from shattering from impact during extreme weather like hurricanes or tornadoes. However, applying security film is relatively inexpensive, and it can make breaking into your home significantly harder—often hard enough to deter burglars entirely—and keep your window from shattering on your floor after impact. For these reasons, window security film is often a worthwhile investment that helps protect your property.

If your window film doesn’t come with an installation kit and its own application solution, you can make your own—but don’t use soap! Instead, use 1 teaspoon of baby shampoo mixed with a gallon of bottled water. Make sure the bucket in which you mix this solution is completely clean.
