20 Best Windows For Home Insulation (2023 Updated)

Bought 2 of these windows for our cargo trailer. The installation instruction says it comes with a D-bulb seal already on the window, but our windows did not have it. Now we have to drive 2-hours one way to the closest town to find butyl tape.

I wish Recpro would have been clearer on this, I would have gladly ordered their butyl tape at the same time and avoided loosing my time and money to drive far to get it!.

It was a total safety hazard. The channel at the top did not disengage at the top when fully opened. Actually it locked tighter and tighter as you tried to open it. Could become a law suit if someone tries to use it as an emergency exit and can’t get out.

If I could give this product a negative star rating, it would be -5 stars. Stick with 3M Branded window insulation film. The small cost increase is well worth avoiding the poor quality of this product, mainly the double-sided adhesive tape! My local home improvement store stopped selling 3M.

so I used Frost King for the first time. It didn’t work as well as I had hoped so I tried to take it off. The adhesive tape would not come off completely and left a tacky residue behind that I still have not been able to remove with even the strongest industrial solvents.

It has been a HUGE inconvenience that I’m still battling. I will NEVER purchase ANY Frost King products EVER again.

Fits our windows and helps save on energy costs! Would recommend to anyone living in an extremely cold environment

I have old windows that should probably be replaced, but these kits work well to prevent drafts in the meantime. The energy savings and overall comfort of the house is remarkably better after putting them on, and I like using them for cold and warm months.

There are some downsides, though. The double-stick tape is supposed to be paint friendly. In my experience, it is not and will remove some paint. They also make the windows look a little goofy, so you have to decide if having a sort of cling wrap over your windows is worth it.

Finally, these can be difficult to install and leave access to blinds, particularly those that are installed inside the window frame rather than along the outside top. If you are struggling to stay warm in a drafty house, this is a cheap way to make a big difference.

I just hope I don’t have to use them at some point.

The quality of this product has gone downhill. I’ve purchased both Duck brand and others for decades – since the “shrink wrap” kind of window insulation kits have come out. and I was always satisfied until this year.

Just bought the 5-window kit (which is really just one huge piece, not 5 separate ones), and: * The first 18″ of tape would not stick to my windowframe. After I cut off those 18″, the rest stuck fine.

But I lost tape to complete other windows because of that. * The plastic is NOT “crystal clear” like the package says – or like others I’ve bought in the past. There is a definite light grey haze to it.

Does not come off, and no matter how tight you make it, it’s still hazy. * It took twice as long to “shrink” it than another other product I’ve used in the past, including Duck’s. Be sure you allow for plenty of time for the blow-dry!! Just very disappointed in this year’s product.

Very. I’d suggest you buy another product/brand for your windows.

I have used this brand for years and there’s a reason for it. It’s easy to use and the tape actually sticks. Last year we bought a different brand from a farm store because my husband didn’t want to make multiple stops at different stores.

We bought two different brands because neither had all the sizes we needed and one brand was actually twice the price of this one. The name brands were well known, they weren’t store brands and we really didn’t expect to find much of a difference.

After after a month of constantly having to retape the plastic a couple times a week I ripped it all off and started over with this brand. We didn’t have an issue the rest of the winter.

The directions for this kit do not tell you to cut the material in half. The plastic is cheap so if you do know to cut the sheet in half it frays easily along the incisions. The tape is cheap and hard to work with, and the sheet and tape are both only exactly enough to fit the window so if you make a small mistake working with the cheap materials you’re out of luck.

Thank goodness I had some better tape from another kit around to fix the mistakes I made. Do not purchase this item, it’s not a good value and you’re better off paying more for a kit that’s easier to use and higher quality.

basically this is 2 sided tape and thin plastic. i followed the directions and, at first, it looked like the answer for my drafty windows. the next evening though the plastic started coming loose from the tape.

the next day even more came loose. so i grabbed some box tape and patched almost the whole window. if you live in an area where wind isn’t prevalent then this may do the trick. but any kind of wind will probably produce the same result i got.

Have very old windows in my very old house. Could feel cold air in room while heater was running. Put up on all windows in room now don’t feel any cold air. Very easy to put up also. No problems at all.

This is great stuff but a little tricky to install. I found it easiest to first lay down the tape,top sides and bottom. Don’t take off the backing yet! Then I rolled the lining out the approximate width of my window, give yourself a wee bit extra and cut it.

I used a big rubber band lengthwise around the roll to keep it from unraveling but not creasing it. Take the top tape backing off and lay down the lining on it as evenly as you can edge to edge. Then take tape backing off left side and only halfway down the right and attach the lining as snug as you can side to side.

Attach it all the way down the left and halfway down the right Now take the tape backing off the bottom and lay down the rest of the right side. Finish off across the bottom. The blowdryer trick really does work and gets it tight as a drum.

A few inches away on high and keep it moving. I managed to get all 6 of my 3×5 windows sealed up and I’ve gained 5° of warmth at least with the same thermostat settings or lower. Another tip, clean the inside of your windows beforehand and you’ll hardly notice the difference.

We bought a 200 year-old house, and over time will be replacing many of the windows. We live in the Northeast (currently 2F, was -5F this morning!), and it gets COLD here in the winter! The old windows are beautiful, but drafty, even with their storms.

I saw this product, its reasonable price, and thought, “Why not?” We covered 8 upstairs windows (2 bedrooms, a bath, and a hallway), one dining room window, and a guest room window. The drafts are GONE and we went from 66-67F in the upstairs bedrooms (with the thermostat set to 72F downstairs to try to get enough heat into those bedrooms) to 70-71F upstairs, without the chilly drafts =).

That was in sub-zero temps outside. These window covers are obviously keeping the cold air out and the warm air in! We can reduce the thermostat a bit and the furnace won’t run so much. I think these things just paid for themselves – exponentially! Not to mention that the bedrooms are MUCH more comfortable.

Ease of installation: Easy, if a bit tedious when doing multiple windows. Well worth the time and minimal effort. How they look: I was skeptical about what these window films would look like; other reviewers said they were absolutely crystal clear, and I didn’t believe it.

But they are – absolutely clear. Very impressed, see photos attached. With curtains up, you cannot see that there are films over the windows. Except for the part where the curtains aren’t blowing in the drafty breeze, ha! I’m buying two more of the 5 window kits today – will be covering some more windows and will have spare materials on hand in case children poke through (not stressed about that, though, because this product is so reasonably priced).

Would I recommend this product? ABSOLUTELY!.

I have used for several years and it has typically served its purpose- but the last 3 years now I have hated and regretted buying everytime! I have noticed a poorer quality and dirty look to it! -I bought this year crossing my fingers (again! thinking oh, maybe I just got a “bad” box last year), my windows are spotless before covering, but once again it looks like my windows are filthy, cloudy-like; or like I smoke throughout my house 24/7- I don’t! And it doesnt wash off! I am switching to a differant brand next year.

3 strikes- I am done!! If you want to be able to see clearly out of your windows- do NOT buy this brand, find another.

Very disappointed in the quality of the plastic provided for the window covering. Product was obviously old as the plastic was dried out and very brittle. Any attempts to get it to stick to the provided tape were met with cracks and breakage.

Very cheap. Complete waste of money and time. Would not recommend. Stick to 3M.

First, one size is 25 foot the other says 110 foot, but it’s 110 inches. The product works well once you install it properly. Prep the surface well for the tape to stick. The biggest problem comes when you want to remove it.

The tape and it’s adhesive are very very difficult to remove. I tried the recommended warm soapy water to no avail. It ended coming off with Goo-Gone and hours and hours of work. I even tried acetone and it didn’t remove the tape adhesive as well as GooGone.

I purchased this product last year as well as this year and on both occasions the tape has pulled away from molding and lost its tautness. The tape had to be taken off with the product “goo gone” and took the paint off my moldings! I spent over $40.

00 on this product both times I’ve used it and the better part of a day putting it on just to have this mess to deal with. I will be ripping it off and returning it for a full refund AND will not give it the benefit of the doubt a third time.

I like these window plastic covers. They are super effective. My only issue was the tape did not stick to the paint on my walls. So I had to tape it directly to the window frame which is just slightly less efficient.

I am still satisfied and I couldn’t get any other tape to stick to my painted walls. So ot must be something about the paint I have.

Very good buy. Would buy again. Served my purpose very well. Thank you

Oh yaa this is going to keep the house warm. But right now it’s hot cause it’s to soon. Saves money especially if your in a old house. Drafty no more.

If I could give this product a negative star rating, it would be -5 stars. Stick with 3M Branded window insulation film. The small cost increase is well worth avoiding the poor quality of this product, mainly the double-sided adhesive tape! My local home improvement store stopped selling 3M.

so I used Frost King for the first time. It didn’t work as well as I had hoped so I tried to take it off. The adhesive tape would not come off completely and left a tacky residue behind that I still have not been able to remove with even the strongest industrial solvents.

It has been a HUGE inconvenience that I’m still battling. I will NEVER purchase ANY Frost King products EVER again.

If done correctly. be careful not to over heat the film. it is a nice and tight fit. clear as glass for any indoor window in your home. I do highly recomend this product. Easy to do. take your time. you will do it right the second time.

order today and get it installed. I thank the 3 M Industries and Frost King for the creation and production of this product. Thank you Max Warehouse for the distribution of this product.

I tried other brands in the past but found the Duck brand tape and plastic film to be of better quality than the others, and, I have been using it for years. Unfortunately, the plastic in the package that I purchased last year had a cloudy film on it.

I used it anyway because our windows without the plastic are terribly drafty and the plastic makes our home so much more comfortable. Unfortunately, the plastic film in the box I just purchased, is also cloudy.

I will be returning it to Walmart. Hopefully, it was just a bad batch and this years box is left over from last years Walmart stock. I will try another package but will be looking for a different brand, if I cant find clean.

I just installed this window in my `76 Ford Van as a replacement for a very old (likely 1977 vintage) slider window with aluminum frame. I like this CR Laurence window because it literally was the same size as the slider installed in my van.

The construction of the new window is rock solid and the seals are nice and snug. The window action is snug which is what you want on a vehicle so there are no rattles. I really like the quality of the build – the outside of the window is about as close to flush as you can get for a flange mount window.

You can mount it with either side up for the sliding action so you can have the window opening with screen to the left or to the right – you’re choice! Lastly the screen was immaculately installed – absolutely perfectly tight with no tears or excess material hanging off the side.

Also, the glass is pre-tinted with a nice, medium tint that will match the tint of your vehicle easily. Just like a privacy tint, not too light but not too dark. That and the framing being black makes this window look amazing.

The other side of my van has a duplicate window but I had to prioritize and try this one out for the slider door. When I get time and some cash I’ll buy a second one to bolt onto the driver’s side of my van for sure!.

It was just what I wanted and works great. The screws were kind of soft and stripped the head easily. Luckily I had extra better quality screws

I installed this window quickly with included trim ring and screws. I used butyl tape or foam tape to fill the gap between the trim ring and the body. It fits perfectly — an excellent window.

I have used this for the last 2 winters. I have 2 cats and a dog and this has lasted the whole winter even with the cats scratching at it and the dog pressing his nose on it. I’m able to cover all 3 of the big windows in my old home apartment with just one box.

I once used the regular kind when this was sold out and I had to replace it within a week. There’s a bit of a learning curve with it but simple once you get the hang of it. I put the tape around the frame first, roughly measure out the plastic, then use a pair of tweezers to pull the backing off the tape.

Do this one section at a time. Peel the top, place the plastic, peel a side, plastic, other side, plastic, finish with the bottom. If you don’t press the plastic hard onto the tape right away you can adjust the plastic on the tape.

This Duck Brand Max Strength Heavy duty window kit was exactly what I needed to save my plants! Our mandatory stay at home orders allowed me to finally have the patio garden that I dreamed of. (Silver lining?) When the weather turned colder I was so sad that I had to say goodbye to my plant friends.

until I realized that I could keep some of them on my beautiful bay window. However it was so drafty until I used this product! It is so easy to install and with the addition to my heat lamp, my tomato, basil and mint plants have continued to thrive.

The window kit included a roll of semi thick pliable plastic that is easy to measure and cut. The double sided tape is the perfect size for my window frame and it was easy to peel the backing off. After plastic is attached to the tape and trimmed to size, I already felt a difference, but when I used the hair dryer to shrink the plastic the difference was amazing! The appearance through the window was pretty clear as well.

I can not attest to the ease of removal because, well, it’s still cold. It doesn’t look too difficult though.

Arrived just on time, very good quality and fits perfectly.

well made. arrived undamaged.

IšverstiShow in original languageAnsicht ist das Fenster sehr gut und verdient fünf Sterne. Leider hat man versäumt das Fenster auf die verschiedenen Materialstärken der Wände und Dämmung anzupassen.

Leider gibt es auch keine kompletten Montagesätze. So bleibt einem nur viel zeitaufwendiges fummeln und tricksen übrig. Zwei Sterne Abzug deshalb.

Shipping jest very first take less a week to deliver it to my home. My two order is 6 dash Quality is very good just transfer hardware from old ones. Very good communication. Happy with this purchase.

Thank you.

Good Quality product, good self help how to online tools, 30 minutes to swap out a Sashe, extra set of hands helpful. new vs 1976 model, new seems to have upgraded design for sealer surface materials making hardware sealer trim swap much less painful.

Great store but Anderson window replacements are ridiculously expensive. Not the stores fault. All of mine have leaked or touched in the middle in cold weather. They are only 25 years old.
