Blocking the amount of sun that shines into your apartment or home can help a lot with your electricity bill. On warmer days, it is important to look into options that will help you reduce heat and stay cooler.

With heat-blocking window films, you can stop heat in its tracks. Films come in all shapes and sizes, so you should have no problem finding the right fit for you. The right fit is important because you want the film to cover your window completely for the best results.

Films add comfort and efficiency to your home. They reject solar energy, reduce glare and make your interior cooler. They also block UV rays, helping you and your furniture stay safe and in good condition. A great option would be the Gila heat control three-in-one window film.

You should look for films that are durable and tear-resistant. They should also be easy to install and be able to firmly stick to your windows. The better it sticks, the better the protection. If you are looking for the best way to stick a film to your window, look for films that use static cling versus a film that adheres right to your window.

The adhesive usually lasts longer, but the static cling gives you more flexibility. With static cling, if you think you placed the film incorrectly, you can easily take it off and start again. With adhesive, once you place it, that is where it will stick. If you are placing a film for the first time, we suggest using a film backing with static cling first to test it out.

If you want to make it harder for people to look inside your home, consider the BDF NA05 window film. It will provide you with daytime privacy and keep the heat down. Films that provide you with extra privacy are great for homes that are close together, or if you live in a first-floor apartment.

You may also be looking for films that are easy to see through. Just because you want to block out heat, might not mean you want to block out light. Another thing to look for is how reflective the film is. This is all personal preference.

What to Look For

  • Pay attention to how much heat and light a film will block. There are variations and one might fit your needs better.
  • Think about where in your house you need the most protection. You might not need to place films all over the house, but just in certain areas that are most affected.
  • Do not forget about your skylights. These have direct sun hitting them and may be the cause of a warmer home.
  • Read up on the instructions. If you have an adhesive backing, you want to make sure you get it right the first time.
  • Films also come in different colors and designs. You can even make your windows look like stained glass if you want to. There are options ranging from super simple to more elaborate.
  • Ask for help if you need it no matter how easy you think the installation process will be. You might want an extra person there to help you place the film and smooth it out so there are no bubbles.
  • If you are looking for films for something other than glass, look for films that feature multi-surface adhesion.
  • The longer a film’s warranty, the better it might hold up. Look for films that are warrantied against bubbling, cracking and fading.
  • Films can be left up in all seasons, so do not think you have to take them down once summer is over.
