Best Home Window Film For Heat Rejection

Here are the best home window film for heat rejection you can install yourself at home, or hire someone to do it for you.

1. Solar Gard

A great option for heat reduction, Solar Gard window film works by blocking 99% of harmful UV rays without interfering with outside visibility. Most of its features can be controlled from inside your home, like an adjustable threshold or a switch to turn off and on cooling that’s based on light detection. This is a key feature if you want to make sure you’re not wasting energy when no one is around. A bonus? Many of these features can be programmed to work automatically, so you’ll never have to think about it again once they’re set up correctly. An additional benefit is that it prevents furniture fading due to UV exposure, enhancing comfort and protecting household items.

2. Solarban

These window films have a reflective coating, which means they offer excellent heat rejection by rejecting nearly 80% of heat. Just remember to keep your windows clean and clear; otherwise, Solarban films don’t provide much in terms of visibility. Solarban films may help cut down on noise pollution, too. Some users report reduced street or lawnmower noise by as much as 50%. While there are several different varieties of Solarban film, all are similar enough that you can rely on one type alone rather than mix and match to achieve optimal heat reduction. For example, Solarban gold is available in three different levels: 30%, 50%, and 70%. All work similarly well at reducing heat, so it doesn’t matter which variety you choose.

3. Ultra Black

Although heat reduction is one of a window film’s most notable benefits, it’s not necessarily its most common. Ultra Black is made with metallic dyes and engineered to absorb, reflect, and refract virtually all UV rays while rejecting nearly 100% of harmful solar heat. This helps keep the home cooler during hot weather by blocking out sunlight. Whether you live in a region that sees scorching summers or somewhere with harsh winters, these features will reduce your energy bills throughout all seasons. In colder climates, it can also help prevent ice-related damage to your exterior glass by shielding it from the intense cold. Finally, when paired with a house wrap as part of an integrated energy-efficient solution, UV blocking Ultra Black could help you avoid cracking windows by keeping them from expanding and contracting over time.

4. 3M Window Film

3M’s energy-efficient window films provide year-round benefits by reducing heat gain in summer and improving insulation in winter. These high-performance films can block up to 78% of solar heat, cutting cooling costs by as much as 30%, while also reducing radiant heat transfer through glass by up to 44%. In addition, they minimize glare by up to 60%, creating a more comfortable indoor environment for working, relaxing, or watching TV. Beyond temperature control, 3M films block 99% of harmful UV rays, protecting interiors from fading and reducing skin exposure. Easy to install and made from recyclable materials, they peel off cleanly without damaging windows if removal is ever needed.

Year-Round Temperature Control with Window Film

Another reason to install window film is that it’s effective at helping to reduce heat loss during the winter months. The temperature difference between the inside and outside of your home causes heat to naturally move from the warmer interior to the colder exterior, leading to heat loss through windows. The film will keep your home warmer, reduce heating costs and make your house more comfortable. Heat gets out of a building through windows as much as 30% of the time, so if you have thermal curtains on every window in your home, you are saving yourself money while making your space cozier. Homeowners also report lower energy bills after installing window film!

The summer months can be sweltering, but a good window film can help to dramatically reduce the amount of heat entering your home by reflecting away the sun’s energy and blocking out UV rays that contribute to fading and cracking of objects inside your home. Additionally, window films can help reduce cooling costs during the summer months by keeping your home cooler and lowering energy expenses associated with air conditioning.
