10 Best Window Film For Sun Blocking 2026 in the United States

The VELIMAX White Blackout Window Film is a great choice if you're looking for a simple way to block out all daylight and ensure privacy in your home or workspace. It uses static cling technology, meaning it doesn't have adhesive and is easy to install or remove without leaving any sticky residue. This makes it perfect for temporary use or renters who want to avoid damage to windows.

The film blocks 100% of visible light and UV rays, so it’s excellent for rooms where you want total darkness, such as nurseries or bedrooms for shift workers. Its white color helps reduce heat absorption better than darker films, contributing to heat control on sunny days. While it does a good job reducing glare and preventing sunlight from heating up the room, it may not be as effective at heat rejection as specialized reflective or tinted films.

The vinyl material is safe for all types of flat, smooth glass surfaces and can be cut to fit different window shapes or used on shower screens and glass doors. However, because it is opaque and fully light-blocking, it won’t let any natural light through, which may not be ideal if you want some daylight while reducing glare. If easy installation, reusability, and total light blocking are your priorities, this film offers a convenient and affordable solution.

The BDF NA05 Window Film is a very dark, black sun-blocking film designed to offer strong daytime privacy, making it difficult for people outside to see in. It excels at blocking 99% of harmful UV rays, which helps protect your furniture and flooring from fading. This film also provides excellent heat rejection, assisting in lowering cooling costs during hot weather by keeping your space cooler. However, because of its very dark tint, it significantly reduces visible light coming through the window, so it might make your rooms darker than lighter films would.

This film is not recommended for double-pane windows, so it’s best suited for single-pane glass. It uses a peel-and-stick installation method with a strong adhesive, and the manufacturer includes free tools and an easy-to-follow guide to help you install it yourself. Just be careful during installation, as the film is sensitive; folds or creases can cause permanent wrinkles.

This product is ideal if you want maximum privacy and heat protection and don’t mind a darker interior. It works well for people looking to save on cooling costs and shield their interiors from UV damage but is less suitable if you want to keep your rooms bright or have double-pane windows.

The Coavas One Way Privacy Window Film is a good option if you're looking for sun protection and daytime privacy for your home windows. It reflects like a mirror during the day, letting you see outside clearly while preventing others from seeing in. Keep in mind, though, this privacy effect works best in daylight; at night, when inside lights are on, you’ll need curtains or blinds for full privacy. The film blocks 99% of harmful UV rays and about 80% of infrared heat, helping to protect your skin and furniture from sun damage while keeping your home cooler in summer and warmer in winter, which can save on energy bills. It also reduces glare, making bright sunlight less irritating inside. Made from durable PVC material, the film adds some impact resistance, giving extra safety for your windows.

Installation is straightforward with the included peel-and-stick film and tools, though larger windows might require more care during application. The blue-silver reflective look may change how your windows appear from outside, which could be a plus or minus depending on your style. This film is well suited for homeowners wanting a balance of privacy, sun protection, and energy saving without complex installation. Just be sure to measure your windows carefully and possibly practice on a small area to get the best results.
