Adjustable Window Insulation Kit 47inX63in(120X160cm) for Winter Keep Cold Out,cuttable Transparent Film 180㎛ Thickness,Easy to Open for Ventilation,Reusable Plastic Window wrap

Used to upgrade insulation qualities of my enclosed single glazed lani. Home Depot's shrink kit that looks very a similar product is 0.019mm. Mellroom is 0.18mm thick. Did you see the trick? HD's has a 19 while Mellrom has only has an 18. But HD's has a '0' infront of their 19. That makes Mellroom's vinyl 9.47 times THICKER than HD's vinyl.Mellroom's vinyl is thick and for me created a better barrier to stop air movement and better insulation qualities. Plus, far more resistance to damage and tearing when I remove the vinyl with its velcro attached from the window to roll up for the summer. The adhesive velcro attaches OK to cold alumimum frames, but it could be upgraded to heavy duty adhesive for use on aluminum.Pro: Overall a great improvement, an easy to install product and economic insulator for the money.Cons: Amazon put a limit of 1 per customer which they then lifted, but only had a 1 small size in stock when I needed 5. So not having enough in stock at Amazon in the winter is a con.

Very easy to install but if I need to open them the Velcro is stronger than the sticky part so it pulls off if the window frame. I'm ok with that as long as they're keeping the cold out.

Great product. Had an evaporative air cooler removed a couple years ago and they left a vent that was covered on the roof but still allowed cold air inside. Kept feeling a draft in my living room over the couch. Tried a few other items but those were too big so returned. This fit the bill. No more draft. I expect it will also keep the hot draft and any bugs from getting in also.

+Thick plastic tears less easy+Hook and loop is easy to fix and reuse for next year-Adhesive failed and had to fix with double sided tape-Thick plastic is heavy and pulls itself down when adhesive fails

Last winter, my spare room was so cold there was frost between the storms and the windows. This year, I installed Mellroom window insulation. It took about 10 minutes per window and was very simple. The outside temperature was nearly zero when I stuck the tape on the window frame and it's holding just fine. I also like the fact that this window insulation is reusable. The Mellroom insulation kit is so much better, the plastic is so much thicker, and the installation was so much less complicated than any product I've used before. If you have curtains on tension rods like I do, you can install the insulation over them. Easy-peasy.

Very disappointed, was super excited about this product. Installed in in 2 windows, seemed to stay ok. Ordered more, for the rest of my windows & waited a while to install as it stayed warm. Then it got cold so installed them in the rest of windows, they seemed to stick good upon installation. By morning every single window had peeled off the wall. I tried to restock them, they seemed to stick back to the wall; but by the time I got back from work they had all come off again. And off course I tried to return them and the y were no longer eligible. Very disappointed. Spend a lot of money & useless... going to possibly have to nail them in to the wall:(

This is excellent! I've tried using the thing one-time use ones before, but not only are they a pain to stay on but they don't seem to last long before they rip.This is so much better! It's a lot thicker, so it's not going to tear or rip. The adhesive works.I was a little leery because I have cats, and they have often ruined the thinner film. That wasn't an issue with this because it's thicker.The only downside, however, is that because it is thicker, it's not as clear as the one time use stuff. I also found it was difficult to get it perfectly flat, so you can see it from distance. I suspect if you had another person helping you and had a little more patience that you'd be able to get it tighter. That didn't really bother me so...Very happy with this, and it cost maybe twice what I'd have paid for a single use one. I suspect I'll get many reuses out of this.

Ease of cutting: Easy to cutSize: Ample size. Plenty of extra material to work withTape quality and seal: Epic failure. If you're around to press on the tape now and again, it works. If you go a few days in between pressing on the seal, it will pop off the wall. The adhesive on the tape needs to be stickier.Based on the tape quality and the lack of a good seal that doesn't have to be tended to, the value for the money is sub par.
