How to Insulate Windows | Cheap and Easy with Plastic Film

Do you feel a draft? Nope, it's not your in-laws coming to town (😬), you may just have a leaky window. For a cheap and relatively easy way to rid your room of this draft, we'll show you how to insulate windows with plastic film and how to insulate your windows for winter (in the knick of time, too).

In addition to keeping your home warmer during the winter, installing plastic insulation film over your leaky windows also works to keep cold air inside during the summer months. Putting window insulation film over windows is a smart idea if you want to reduce energy costs and keep out drafts during the colder seasons. Applying plastic insulation film to windows can actually cut the cost of your climate control bills up to 40%.

We know - plastic for windows sounds wild, but hear us out. You can essentially winterize your windows for very little cost, insulate your windows with minimal time or damage, and seal your windows for the winter before the day is done.

Things you might need:
1. Window Installation Kit
2. Window Insulation Film
3. Window plastic wrap

Watch our comprehensive instructional video in which we walk you through each of the simple steps for installing plastic film over your windows.

In less than two minutes you explained the process better than all the 10 minute videos I've just watched.

Short video, no yapping, good explanation and very funny wife joke, great job! I'm still laughing from that joke

I’ve found that if you don’t apply the film perfectly to the double-sided tape, meaning there’s any wrinkle to it, it allows air in. And if the window is very drafty, the air squeezing through any small gap can pull the film away from the tape over time.

used bubble wrap last year (on double glazing) -big improvement - put it up again this year - good thing is you can take it off and use it again - you only use water to stick it to the window - plenty of vids on

The only real problem I had was a too short cord on my hair dryer. My husband and I did this today and we are both in our 70s.

Thank you for your video! I was just planning to put the plastic up. You made it easier for me.

[twilatharp]

This is the best explanation anywhere. Thank you so much! 🙂🎄🎄🎄🎄🎄🎄🎄🎄🎄🎄

Would it help more if I put one on the outside too???

[Posh_pennies]

Can you install on the outside to prevent insects from coming in through old wooden windows?

Box cutter on the painted window frame?!

[markdorais]

Succinctly and well stated. Thank you so much. 👍👍👍👍👍

I clean the sticking surface with rubbing alcohol and use clean packing tape on the edges of the film.

Incredibly challenging to separate the adhesive backing on tape.

Thanks for showing the process. Your sealed windows at the beginning (minute 0.31) show a lot of moisture trapped...is this an issue for growing mold in the winter? Does it remain or dissipate? We're struggling with moisture on our double-glazed windows causing mold growth on the wood.

Thank you so much ! Great help for insulating the windows 😊

So basically, we buy window film from the store and follow the manufacturer’s instructions, great tip. I don’t think I would have thought about doing that. I’m glad I found this video.

I was right there with him...until he used a box cutter to trim the plastic. Unless you have surgical precision, it's sure to also cut a thin score line on the underlying frame. There's gotta be a better way!

[Noneyaviz]

my only problem is if i ever want to open the window to refresh the house with some nice fresh air I cant.

[caibaya]

I don't have this kit in my country. What type of plastic wrap could you use?

[alexonline]

thank youuu this is exactly what i needed!
