Window Insulation Film During Summer
Aside from blackout curtains, one way to keep your home cool in the summer is by installing insulation film. During the summer, insulation films help block excess heat from your windows while keeping the room bright and non-glaring.
At the same time, the film blocks out up to 99% of harmful ultraviolet rays, protecting your skin and preventing your colorful home furnishings from fading.
Some insulation companies offer promos during the summer, so if you want to save on installation costs, you should check with your local providers.
Window Insulation Film During Winter
Similar to how it functions on hot, sunny days, insulation film can effectively trap the heat inside your home and prevent the cold from entering. Insulation film is a perfect DIY solution for old windows that do not keep drafts out and cause your electricity bills to soar.
Some of the benefits you can get from window insulation film include heat dispersion and lower electricity costs without giving up natural light.
Pros and Cons Of Window Insulation Film
Like any other product, window insulation film comes with a slew of advantages and disadvantages. However, that doesn't mean it's a product you should avoid. Take a look at our list to find out if insulation film will work for you.
- It's low maintenance and will last a long time after installation.
- Creates a slight tint to your windows for a boost of privacy and reduces the glare from the sun.
- Insulation film kits are relatively inexpensive and come with almost everything you may need for installation.
- Helps cut down utility costs by 40% to 60% by reducing the energy lost through windows.
- Helps block up to 99% of UV rays to protect your skin from harmful exposure, as well as helping preserve the color of your furniture that's exposed to sunlight.

- You can't entirely rely on the film to warm up your home because it's not as powerful as fully integrated heating systems.
- You are only protecting one side of the glass surface, so the other side may still absorb heat and cold.
- Certain window manufacturers warn users that their warranty will be voided if insulation film is installed on the windows. You may want to check with your manufacturer on this.
How to Properly Install Window Insulation Film
Before you begin the installation process, prepare your installation tools and materials. These include:
- Window Insulation Kit
- A pair of scissors
- Measuring tape
- Window tape
- A foldable ladder if your windows are too high
Once you have your materials ready, you may now begin insulating your windows with film. Do note that you can install the film either outside or inside the window, although, you may need to upgrade to a more heavy-duty film material if you're installing the film outside.
- Get the exact measurements of the window using the measuring tape.
- Wipe the window with a damp cloth to make sure the application surface is clean and smooth. You should also ensure that the window locks are snug and secure, as you won't be able to move the window around during the installation process.
- Apply the window tape to the windowsill, leaving a gap of at least one inch. Firmly press the tape to the surface to ensure it has adhered.
- Lay the plastic sheet that comes from the insulation kit on a flat, clean surface and trim it according to your window measurements.
- Peel off the paper from the window tape and place the plastic sheet on top of it, pressing each side firmly to prevent gaps from forming.
- Once you're sure there are no gaps for any air to pass through, then your insulation is all set!
Other Ways To Insulate Your Windows
Believe it or not, there are a couple of other ways you can insulate your windows aside from using insulation film. Here are some of them.
Bubble wrap is often used to insulate greenhouses, but using it for your home is a great alternative if you don't have insulation film. Be sure the installation is airtight. Note that bubble wrap can make your window look fuzzy and hazy.
Removable magnetic window insulation
If you're not ready for a semi-permanent installation to your window, consider getting magnetic window insulation. It's usually made from vinyl and is easy to install. Plus, you have the option of moving it around if you're unhappy with the installation.
While it's generally better for filling in small gaps along your windows, a good quality rope caulk can still offer a decent amount of insulation. You should apply the putty on both sides of the window to ensure optimal insulation.
For a foolproof option, grab a couple of thermal curtains for your windows. These special curtains are manufactured with a unique lining that blocks out light and excessive heat and keeps a room warm in winter.
Probably the easiest to maintain among the options on this list, thermal curtain can be tossed in the laundry for cleaning, so you can use them again as soon as they dry.
How long does window insulation film last?
If it's installed correctly, window insulation film in the best conditions can last for up to 20 years. These conditions come from a wide selection of factors, such as the film's material, the condition of the window itself, and your local weather.
How much heat is lost through a window?
A house loses about 18% of its total heat via windows if the insulation is not good enough. Convection, radiation through the glass, and heat transfer through the window frame are all responsible for heat loss through the windows.
It's unsurprising that you might find window insulation film a little daunting to use because of varying opinions regarding its effectiveness. Don't worry, because most window insulation professionals recommend it, and this is proven by the wide availability of film installation services.
Furthermore, insulation film is long lasting. If properly installed, it can last you for many years, allowing you to save money on energy costs.
