- TpecenkaEasy Installation, high qualityEasy to install, works as it should. We live in and older home, we could probably use new windows, but in today's economy- who can afford that?
We've used other brands in the past years, but this one has really made a difference in holding in the heat. Installation is easy peasey! - Kathleen A.Effective and easy-to-use window insulationThis window insulation kit works great and does exactly what it’s supposed to do. It was easy to use, and the instructions were straightforward. Once installed, it sealed the windows well and helped reduce drafts. The material feels durable enough to last through the winter, and it fits the windows as expected. Overall, it’s a simple and effective solution for cold weather.
- HeatherMake sure to unfold them!!!It was great!!! It worked!!! My electric bill went down by $75!!! It was crazy!!! I'm very thankful for it!!! It's very sticky it doesn't come off!! It's easy to put up it's easy cut. You have to unfold them, found that out!! I only have four windows to cover!! But it is those with ease and plenty of material left. The sheets are big!!
- BTCThe tape doesn't always stick well. One person can do the install.The double-sided tape included sometimes sticks to the wall or window frame, and other times it does not. I suspect this is because of incompatibility with some types of paint. I ended up using clear box packing tape to secure the edges of the plastic to the wall or window frames. This is behind the drapes, so out of sight. The shrinking works fine and make the plastic almost perfectly clear to look through. There is a film that is sometimes visible. I'm not sure if this is from packing powder used to make sure the plastic doesn't stick to itself or what, but it is sometimes visible based on the angle of the sunlight coming through the window. The box states, enough to cover up to 5 windows. This is true, but to do 5 windows, they will need to be fairly small. The funny part is that they are clear enough where flies and other insects run into the plastic as they fly towards the window light. The plastic is stretched tight, so they bounce off it and a drum sound is heard. I have two windows opposite one of my rooms, and the flies will go back and forth between them, making the drum sound each time they hit the plastic. This isn't a problem, the fly swatter comes out, and they are swatted. I put this here so if you decide to purchase and install this kit, you won't think you're going nuts when you hear this strange drum sound from time to time. My home is an old modified mobile home into a permeant residential house. Being so old, it has single pane glass. I'm hoping this kit will help reduce the winter heating costs. We have a few low 40 days/nights so far this year, and the kit seemed to work pretty well. The lowest the house has gotten to was 69 degrees on a 42 degree night. Other than the back door (large window in it) and a 3x4 window in the mudd room, all windows in the house have the kit installed. It took two kits to do 3 bedroom windows, 2 mud room windows, 1 dining room windows, and 1 living room window. I only gave a 4 star because of the tape issue. The plastic itself is easy to use, and shrink.
- JerryKeep comfortable this winterThicker plastic than the average window insulation kit. Easy to install and makes a huge difference in comfort level. We have been having a cold spell here in the North East, and after installing this Duck Max Window Kit, the living room and dining area heats up quicker than before installation, no more draft, keeps the heat in even after turning heat off. Very happy with this purchase.
- SparklesNice qualityNice thickness . Does the job. I had the thinner plastic to compare it to and this one I’d definitely stronger . I use it to cover my whole fireplace in the winter. I know it seems counterintuitive but we don’t use it and it lets in so much cold air. Also used to cover air conditioner units in walls and some drafty windows. It really cuts down on cold air.
- Jake KWork great, but plastic was very dirtyWorked great as always, but the plastic was clearly either dirty or wet before installation and now all of the dust is attracted to this affected spots. I’ve used this for years and this set is so dirty and hazy compared to usual. It’s impossible to clean these without making it worse, either messing up the seal or leaving streaks/adding static to attract more dust. The streaks in the pictures are across the entire roll like the machine rolling them was leaking or something.
- SashaTake your time installingAmazing. I put it around my window frames due to the way it is. It was a simple install but a little tedious but once you shrink the plastic, it looks great. I live in an old uninsulated apartment so anything helps. I did this on just the living room windows and already noticed a difference of warmth the first day. Must buy. The tape is very sticky. The plastic wasn’t thin or easy to tear. Simple to cut since it’s folded.
