You can easily and cheaply use tin foil or cardboard to black out your windows. Save a pretty penny by cutting either material to the size of your windows and taping it to the window. This is one of the easiest and most budget-friendly blackout solutions, but it definitely isn’t the most aesthetically friendly.  

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.

The lifespan of window tinting depends on several factors, but a high-quality, professionally applied tint can last anywhere from 5 to 25 years, with premium tints lasting at least 15 to 20 years. Key factors influencing longevity include the quality of the film, the professionalism of the installation, and the type of window. Some companies offer lifetime warranties, while others may only provide a one-year warranty or none at all, so it's wise to verify this with your service provider. To prolong the film's life, clean it gently with a microfiber towel and mild cleaning solutions. Avoid harsh, abrasive, alcohol-based, or ammonia-based cleaners, as well as sharp tools or scrubbers, which can damage the surface.

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.
