Yah Kathy, basement windows are superb place for this insulation. Hope your toes are a bit warmer this winter season. I had been thinking about insulation for our windows facing the north for winter. Great timing for me. Even in northern Alabama it can get cold. Especially that north wind that makes the entire side of the house colder than the rest.
Thanks for the tutorial. I am going to use this on the window in my front entry door, it is the only window in my home that is not double paned. Thanks for the tutorial about insulating windows. This looks doable and affordable and will be something I will work at doing before the cold weather sets in. I would definitely use the window film in the window that is in the finished room over the garage. That window seems to be the worst when it comes to the cold weather.
Thanks again for an awesome tutorial! I live in an older mobile home in Wittmann AZ. In preparation for the winter I caulked the windows inside and out.
Adding the bubble wrap and plastic film will be my next project. Oh my gosh Celeste, I can only imagine how cold it gets. Great suggestion with the caulk. That reminds me, I bought removable caulk for this tutorial and forgot to show everyone my idea. This was a great idea and I am so happy you shared with us.
I do have a question though, I have double pane windows and often I have moisture build up in between the panes. With this extra insulation, I am sure to have a lot at the end of the winter. How does one clean that moisture out of there? It has been a challenge that I have yet to figure out. Thanks again. I totally understand your concern about the moisture. My assumption could be wrong but I think the seal between the panes is broken somewhere. I managed to remove moisture from a double glazed window by removing the double gazed unit from the window frame and drilling small holes at the top of the unit and then by using an electric hair dryer warm the unit until the moisture is displaced from the pre-drilled holes, which are then re-sealed by using an appropriate sealer or glue.
I carried out this repair several years back and it remains good. Thanks so much for sharing because a lot of members have had the same issue. I bet this will come in handy.
I may use it on the other north windows, and definitely the basement windows too, just for the saving heat factor. We heat with pellet furnace but there are occasional times we need to use the oil furnace.
I have single pane wooden windows that are very drafty. I bought a big roll of bubble wrap. On the back of the house I used double layers of clear bubble wrap. To apply I used a spray bottle with a little bit of dish soap. Just spray it on the window and then apply the bubble wrap. I also used some painters tape on the corners, just in case. On the front of the house I have a big picture window, I used the film on that.
Awesome tips Lilly. I have happily used bubble wrap for several years, but have never used it with a window insulation kit. There is an easier way to put up bubble wrap: spray the glass with water, then while still wet, press the bubble wrap to it. This works great and the wrap has stayed up the entire season Minnesota. My xl windows and the patio door have needed tape along with the water spray to stay in place. I suspect the window insulation kit would help that, too.
I bought a huge roll of the bigger bubble wrap, the kind used for furniture. I cut pieces to size. I used a marker to label which window and have reused the wrap each year. Wow Hilary, thank you so much for the great tips.
Love you idea of labeling and reusing the wrap. My house was built in I have been able to install storm windows on most of the ones in the house. On the front of the house is also a window that is going to cost a fortune to insulate. Older homes have some of the prettiest windows. But they come with a price of being super inefficient. I bet this would help you Tim. Good plan, those sliding glass doors are pretty but the huge pane of glass can let in a lot of coldness.
I plan to use this on my glass porch……. Wow, this is like putting an overcoat on over a sweatshirt. I have a window with a cat door and I am doing this to that window. I plan to cut a slit for the cat door and then tape around the door. Any good tricks for the cat door it self?
Just keep in mind you can not see out very well. We usually keep 2 windows free of bubble wrap just to see outside! Winter can get depressing if you let it! Love this idea. We just moved to a newer house, but the windows are metal previously we had vinyl triple pane.
We are noticing condensation on the windows inside the house and I have to wipe it up with a towel. Thought we had left that back in Michigan. If this works, it could save us thousands…from having to replace all the windows. Thanks for the great tip. Congrats Heather on your move. Yep, that bubble wrap will totally come in handy. It would be a good experiment. This idea would be great on all the basement windows. Thanks for the ideas.
My daughter just moved into her first apartment with 3 other women. If I win, it will give me an excuse to go visit her!
Thanks for the tutorial, very timely! Hope she stays nice and cozy up in Portland Karen. What a great idea!! Thanks, Jean. Here in New Mexico we have companies that will set you up with solar for the price of your existing bills. We have been attaching clear plastic sheeting over the outside of the windows on our north facing bedroom during the cold months. We do have radiant heat which is lovely as long as the boiler holds out. Thanks Jeff for the interesting idea.
Hey Lannie, hope your boiler holds up this winter. Keep me posted on the solar idea. Fantastic Idea. Live in Pa as well and last winter was a nightmare. The bubble wrap really makes sense. I plan on using this on the windows in the master bedroom and the spare back bedroom where we seem to get a lot of drafts. I bought removable caulk yesterday and this wonderful idea for my old loose window panes is just what I needed.
Thank you for the tutorial. Let me know how you used the caulk Carol. I bet a few other members of our community would love to hear how you used it. The winter seems to bring our the fixer upper in all our houses, lol. This is a great tip Jeff!
Thanks for sharing it. We have two windows that are so bad, the wind will actually blow the plastic off if I shrink it. If we leave it un-shrunk it can be rather noisy. Any tips for these windows? Oh and will the large bubble wrap work as well? I bet the large bubble wrap will work Kari.
You might want to use temporary caulk to seal the gaps around the windows and even between the two sashes. Then you can remove the temporary caulk when it warms up. My husband and I sold our big home in August after he had 3 heart attacks. It was just too much for us as far as upkeep.
We have downsized and are temporarily living in our 5th wheel camper. We are searching out ways to insulate and get ready for winter. We live in the Blue Ridge Mountains and it can get pretty darn cold here. I love the idea of the insulation with the bubble wrap as well as the other wrap. It just might help us to stay warm this winter. Thankx for this tip!! How scary is a heart attack, right!! Downsizing is always a great option to keep things simple.
We replaced our south facing windows but still have to do the north facing windows. My 11 yr. Especially last winter. It was a brutal one. Luckily no freaky pleas for help have scrawled across his stomach lol. I grew up during a time in life when my Dad would weatherize the windows every winter with some sort of strips and plastic sheeting. I can only imagine how much the bubble wrap idea could have helped out back then! Wish we had known. Great idea!
So glad you shared it with us. Thanks Shirley. Oh my goodness!! We literally just took all the curtain down and are doing fall cleaning. Perfect timing as it is just starting to get a bit chilly at night with the windows open. The sliding glass door in the kitchen needs this. I love the window tips and all the tips in the comments.
As a temporary measure, I tacked a folded king size white sheet around the frame of the window and it seemed to keep the room warmer. Funny story—my son had been complaining that it was much colder than before so I finally checked the window and it turned out that the lawnmower must have thrown something and busted out a fist size hole one of the upper window panes.
Poor kid. I will definitely try your tips. Those aluminum windows can be really tough to replace. Thank you! This looks great. I have plenty of windows that could use this. Any ideas on how to stop losing heat through the floor?
My home is built on a concrete slab, and my lower level has ceramic tile flooring. I will use it to help them winterize this beautiful if somewhat leaky craftsman located in Sulphur Springs AR. We wonder if it has to do with our unfinished basement underneath those rooms. Possibly Ashlee. You can add insulation there to prevent drafts from coming upstairs. The whole backside of my house is windows and they definitely need to be insulated.
This information will give me the encouragement and help I need to do the job. May take a while but it will pay off in the months to come. Thank you so much for the help you provide and I plan on checking out your website.
Feeling determined. I definitely will be using this on 7 of my windows. I set the thermostat at 62 at night and when we are not at home and 65 when we are at home. Thank you for the great DIY information. Thanks so much for the great idea — this will be our first winter in the Blue Ridge Mountains and the propane we have been heating with so far is really expensive. It definitely is a great option Sandra. Windows are a great way to bring your 80 year old home up to date.
We have really bad drafty windows in our bedroom in this rental house. I used this plastic shrink with a hairdryer kit before. During the night the wind would blow in, the plastic would bow inward, and the popping off of the tape around the sides would keep me up.
Theres just no tape strong enough that will keep the plastic anchored to the wall or trim. Sounds great. Do you think this would work with windows in summer in Arizona?
I am for sure going to try it. Thanks for the tip! I would use the kit in my basement windows. They are the old kind of windows that drop open with a latch. My house was built 58 years ago. My dogs, Teddy and Chico would like it warmer where they sleep. The floors are freezing so I know I have issues in these older windows. I am a single but I think I can do this all by myself. I appreciate learning how to do things around the house and feeling accomplished that I can do them.
My utilities usually average My dog does not stay outside all of the time, but he does love to go out. He also loves his dog house. I duct taped it where the tarp met the opening.
Oh man!! It amazes me how much warmer it is inside since I did this. With winter approaching, I thought somebody might like to know a way to create an inexpensive insulated dog house. Lovin this idea! Saw the bubble wrap idea with a little different technique a couple days ago. They said to mist water on the window and then apply it directly to the window.
I think I like your method better. This will work great on my north-facing windows that are at times, I think, windows in name only. Several years ago, I learned a trick to stop drafts on windows. Make a curtain for the window, allowing some excess around the sides so it extends over the frame slightly.
Make 2 pieces and sew them together on 3 sides. Insert foam trays like grocery stores put meat on into the curtain and stitch up or pin the last side closed. I made the slot for the curtain rod on one end before inserting the meat trays. Hope this helps somebody! Thank you so much for sharing it. Any tips to help with drafty windows are priceless. As I live in a double wide mobile that was renovated by the previous owner.
Your bubble wrap technique is wonderful that I had not thought about. The inserts of glass cube windows in one bathroom and laundry room is where I will start. And it just may float! I would love to win a window insulation kit- it would really help heat up the bedroom and kitchen! I love the bubble wrap idea-though not on main windows, as it will definitely hamper the view.
This kit will be used in my basement apartment. I live in the far north of Ontario Canada where is not uncommon. Last night it was already with the wind-chill, without. I put plastic on my windows every winter to help cut heat loss. If I was lucky enough to win this I would be putting it on my battery room window which faces North… I live off the grid.
I leave my plastic up all year…it even helps to keep the house cooler in the summer, saving on air conditioning bills! I replace it in the fall when the plastic goes on sale! Have saved hundreds through the years! I am in Wisconsin and plastic my windows for winter as it gets really cold here but this year I had to do one of my doors so I put towels rolled up where the big drafts come through and then put the plastic. Hopefully it will ward off the high temps as well.
Let me know how it works out. Living in a Fema trailer is cold and drafty. I atleast want to do the 3 Windows on the N side. I like the way the light still comes through. I was afraid I was going to live in a dark dungeon this winter. I put a piece of weather stripping where the window meets the sill and seem to cut a draft. I recaulked the outside of the window and also installed thermal curtains to hold back the cold, recommended by my electric company after an energy audit.
I would love to do this! Every time I suggest it he shoots it down. You will be able to stretch that extra double sided tape to more Windows or even different projects. I have used film fpr years.
I would use it on my large picture window on my 50s house. I will use this in my bedroom as I lay there sleeping I can really feel the cold, so I am hoping this will make a difference… Thank you so much.. Wish I would have seen this earlier! I put plastic on the window but it collects so much condensation, her carpet gets wet.
Her room is still very cold! Any other suggestions? I have used these kits for years!! I put one on the inside and one one the outside!! I love that I can still see out the windows unlike regular plastic!!! We need to do this with our enormous picture window in the living room. It is a single pane window, and is larger than three regular sized windows side by side.
Plus there are double paned windows on either side of it. All in all, the entire expanse is about eight foot wide by about five foot tall. Try finding a window kit to fit that! I always try and cover my windows to help keep heat costs down. Never thought about bubble wrap before… Will try very soon. We leave in a mobile need i say more windows are draftey!
Window insulation kits cost are overpriced. I refuse to pay that much for plastic and tape. I can cover MANY windows for a fraction of the cost. Hey I like in Whitehorse Yukon territory and we get down to 40 below of not colder on the odd day…. My bedroom is downstairs and very cold.
Cool idea. I need this for my son. They just had a preemie baby who is now home from the hospital, but their bedroom, where the baby also sleeps, is in the cold basement with leaky, cold windows. This would make the basement so much warmer for that sweet baby. This also gives a little privacy plus allows some light to creep into the interior of the van. I would love to be one of the winners of the Window insulation kits. I have used a roll of plastic table covering I had left over from my kids parties.
Down side was the inability to see outside. My bedroom is always at least 20 degrees colder than the rest of the house. For curtains, I use 2 denim shower curtains that I sewed valances to the tops. Still cold. I heard about the bubble wrap, but I have heard 2 different ways to affix it… Bubble side down and bubble side up. I was thinking of using push pins and would love advice on how to keep a peephole so I can look at the full moon without going outside as I walk by in the middle of the night?
Thanks, again! How would you go about getting the tape to properly adhere to the old steel framing on basement windows, or maybe the concrete surrounding? I use bubble wrap on non insulated windows. All I do is cut it to size and wipe the windows with a wet cloth and then place the wrap on the window. If it starts to loosen after a few weeks I just re-wipe and re-stick. I use bubble wrap that I receive in packages so the whole process is free and it works great.
My house can do with new windows that are better insulated this winter. I should get one of these insulation kits now that I know that I can afford to buy one. I want to try this on the shop windows.
My husband and I spend a lot of time with projects out there. We have a wood stove for the winter and here in NC it gets really cold.
The windows out there are older and the insulation would help keep it toast. We love DIY and enjoy your great tips. I have a neighbor that burns wood all winter and since my windows are so , so crummy that is a great solution for me. I have to buy a new furnace this year but maybe next year I can do something about the windows.
Thanks for the great tips, Love your site. I am so excited I found this. We are retired and are renting a home that is about 35 years old and the windows are old and leak badly. Last year we had a power bill in excess of If we want the downstairs warm, we bake upstairs in the bedrooms. Such a difficult time of year for us.
Please help us. You could try the plastic film technique this year Katherine. Keeping it warm will also help me medically. We have a wood burning stove so keeping cold drafts out of the whole house wound be great! Gotta keep the kiddos warm!!! Jeff, the bubble wrap is genius. As is doing the basement windows. I never thought of going that low!
Mostly because basements in PA are creepy dungeon type places…would the double sticky tape even attach to cement? Also, while not a weatherization tip, its a pet tip that helps with weatherization…if you have cats that love being all over your windows no matter the temperature and they find the plastic a direct insult and proceed to shred a window or two every winter, get cheap car floor mats with spikeys on the bottom. Tack down if necessary.
Cats and dogs too hate the feel of the gripper spikeys and will leave the window alone saving your hard work. In this article, they specify to put the bubble side against the window, without the airspace. This doubles the R vue of your window.
My house has old roll out windows that do not seal very well at all. I would love to use the window film for both winter and summer. Keep the drapes closed helps a little, but not enough. I have 4 very old orihinal basement windows that need to be done.
Tip insulate between the joists and foundation of the basement. I use it on every window in my house. I live in a drafty apartment duplex and we have to plastic every year. I love the idea of adding the bubble wrap. A few extra insulation kits would cut down our costs for sure. We do every window in the apartment so it gets costly! Thanks for the great tips. We have an almost year old house in Rochester, Ny and the cold is coming.
We have some new window but mostly old one and I look forward to trying this on a bunch of the windows thanks for the great idea. Thank you for the help. Last year I used just bubble wrap, and it blocked most of the chill.
Hopefully adding your second step will stop it all together. We were finally able to replace a few old windows. Our friend, a contractor, installed them. They all leak, lesson learned. Your ideas are so sensible and affordable. Thanks for all the tips and instructions. Surely I can do this. We moved to Colorado this summer and have yet to go through winter. I am going to tackle the basement windows first.
I have taken plastic trash bags or smaller ones from grocery store and roll length or width wise, depending in the size of the space you need to close up. Even seal the bags in the gaps with packing or masking tape.
Doors and Windows. We live in a 40 year old house with original windows so to stop the wind and snow from coming in this is what we always do. Also the electrical outlets on the out side walls need insulating. Here in Wisconsin we can purchase foam outlet pieces to put behind the outlet and switch covers on the outside walls.
I wash it well and soak it in bleach. We bought a home and it has newer replacement windows in the family room. The windows face the west. And let me tell you the air that leaks in around these windows in the winter is brutal! Our heating bills are outrageous. If you sit on the couch next to the window, you actually feel a breeze coming in. This kit sure would help us trim our bills down and make this room cozier! Thank you for the info!
Looking forward to those colder temps…a little bit more. I also use door strips to prevent drafts. Windows are old and in bad shape. I simply spray water on the window and the bubble wrap sticks.
Bubble wrap is cut to fit and stays all winter. Then I remove and roll it up and store it. I have 25 yr old dual pane aluminium windows. Now if I could figure out how to keep my floors warm. Need to insulate under the floor I guess. Crawl spaces are not my thing. If you have a two car garage and only use one side, use the bubble wrap layers and then the final plastic film over the complete door to keep the draft and cold out.
Pick the one with the most draft. I would use them on all of my windows if there was enough. My biggest problem window is my front window. It leaks so much I can see my curtains moving when it is windy out. To save money I check what the weather is going to be like daily. In the summer if it is cool at night I turn off the air, open all the windows and put fans in three of them throughout the house to rotate the cool air.
I make sure to set my alarm for when the air is going to start warming up so I can close all of the windows and curtains. This really helps to cool the house down and keep it cooler throughout the day. It really cuts down on how much the central air runs. In the winter If it is going to be sunny out I open all of the curtains and let mother natural heat the house for me.
If it is cloudy and windy I close all of the curtains. It takes a little planning and a little work but I believe it pays off each month. My girlfriends house has very old windows and very bad insulation. She has 3 levels and lots of windows so cost will add up but I have to believe the savings in heat escaping will offset it quite a bit!
Im doing all our spareroom windows this winter and also making draft busters for door bottoms. Also doing my bedroom windows just to add that extra help. I am starting chemotherapy and am not messing around and trying to be as warm as possible over our long Michigan winter. It has a window as well as its insulated steel. I would like to use the kits to help out a friend on a VERY fixed income who just moved into an older trailer house in north central Texas.
So that it will help keep her heating costs down this winter. Thanks so much for this information! It gets so cold on that side of the house East facing windows. Being a senior citizen this will be a great idea to help our winter bills. The bedroom and living room is where I would like to use it. I could open the curtains and let sunlight in without nosy neighbors looking in. We have long winters in alaska sometimes so the tape is on a long time.
I would first use this in our upstairs bedrooms, sunporch, garage and basement. These areas allow a lot of cold air into the main areas of our year old rental.
I live on a fixed income Social Security and moved into an apartment that has metal-framed windows. All of the windows will benefit from insulation, but previously broken windows have had Plexiglas stuck into them. It has not even been caulked, and when the wind blows, they bow inward.
Although I plan to tape or caulk it myself, I am not impressed with its insulating value…especially since we are predicted to have an extra cold and snowy winter. Thank you for the information. It will help tremendously! Hope this helps Constance and it should help lower your heating bills. I would use it on a large picture window in living room.
When the wind blows hard you can actually see the curtains move. I know the feeling Phyllis, we have the same issue with the windows on the front of our house. We own an older mobile home in mesa az. And they were NOT built for the weather here. No insulation and the windows are worthless. I try to say money on heating bill in winter, because summer bill is a killer. Hope it helps you with your heating bills.
Especially this winter. This always causes me trouble. If you are not sure if the tape will take the paint off with it, you can put the tape on the outer edge of the windows, next to the wall. It may still take the paint off, but at least you only have to repaint the very edge of the window, not the whole frame.
Thanks for a great giveaway! We have an older mobile home. I would do my bedroom windows and maybe the living room too. I hate drafts and can always feel them. We have a house that is years old!!!
Single pane and wavy glass everywhere! I would love to try the bubblewrap…we live in pennsylvania and heat with coal…. I think that your explanation above and through the video is one of the best. You did not tell us the thickness of the bubble wrap that you chose and you did not tell us if you put the bubble side to the outside or inside to the room. Did you have to put another section of double tape on the top and bottom ledge to make the overlap of the previous section? I am thinking that the previous piece would have hogged up the double tape and when you went to overlap it would have no place to stick, unless you put a new segment above and below.
You are the first to not put the bubble wrap directly on the window. Which when cutting to the size of each pane, adds a whole volume of possible extra useless effort. Others have also recommended that we search furniture and similar stores for the bubble wrap they get in on their items and before they chuck them.
I look forward to seeing more of your videos and reading your articles. I will look back here to see if you have answered my questions above. Thank-you very much for your help. Please Help: Thank you for your expert advice!!
I put water on it and it is not sticking to the window Please advise! Thank you, Nancy. Just bought a Civil War home! Huge windows and lots of them, Drafty of course.
Built in So yes need to do this at once!! You can do the bubble wrap and the plastic like Jeff showed in the video, you can also buy window plastic with the double sided tape for the outside of the Windows and pattio doors. Works great. You put it on just like you do the inside Windows.
Every little bit helps when trying to keep costs down. The bubble wrap tip is ingenious! Will a hair dryer take it off of the wall as well. I made a blackout panel for the bedroom window and used it this summer between the shade and the drape to keep the heat out.
So many nice patterns or even different colors if you wish. Cuz we live in a rental house. We moved into a very old duplex a few months ago. How much is the window cover cost. Do I have to wash the widows first. The woodwork to. I guess I should. Can I just cover the window screen with plastic film? I dont want to cover the whole window. Great tips here. Definitely going to use the bubble wrap idea! One thing to note, i believe the Frost King kits are a one time use only.
Wasteful and not cost effective. I went and bought a roll of very heavy clear plastic. It can be used season after season. Is there something to use under the tape that will make it easy to take off without messing up the window frame?
Would glue work and would it stay invisible or would it turn yellow after awhile? We cover half the window with it and then the other half with the clear. We also wrap our front porch in the clear plastic and keep our plants out there in the winter. It creates a greenhouse on the front door and eliminates any cold air coming in around the front door and the 2 Windows on that porch. I hope that this helps some one else. I have a 54 year old home and had the windows upstairs all replaced with dual pane gas filled windows with vinyl frames five years ago.
They were installed into my older single pane frames. But my older steel framed basement windows were never updated. They have now gotten cracks in them and the windows are not removable. So i am trying to get the window kits for my basement needs but financially like half of the us have been out of work since january. So if I could get these kits I would be most greatful.
I live in Gouverneur,NY, Thanks in advance. That sounds cool Perry, make sure to take some pictures. Jeff… Is there such a thing as putting plastic on the outside of windows? Or can you apply the tape somewhere inside the trim on the actual aluminum windows? But for now I put up visqueen I just popped out the screen and cut the visqueen to fit and put the screen back in.
Now I like my room dark so I used black visqueen. And I replaced the window unit. And I keep the. So my central a. And my electricity bill is actually going down.
Since my room was the lani has been sealed and blacked out from the visqueen. So this stuff is amazing. It gave me an cheap but good fix. Hi jeff, need a little help here, I weatherization my windows using just the plastic film.
And not the bubble wrap cause I still want transparency.. It was fine the first day but the second day I can see the frost on my glass window, is it possible there is a Leake in the film?
Pls advice. Mist the window with water, and stick the flat surface of the bumble wrap directly to the window. It will stick all winter with no issues and all you have to do to remove is pull bubble wrap away and dry window.
I see your website needs some fresh articles. Try using a hair dryer to heat up the tape that the plastic film is attached to.
Will give it a try. Lol, whatever works Meg. Thanks for sharing. Do I use the plastic wrap for both the inside and out or just one? If just one, which side would be better? So awesome!
