Insulation Worked Well!
This was an awesome product and great for keeping the 100F plus heat out of the house! We used it in a bay window and it cooled down the room tremendously by keeping the heat outside! I’d definitely recommend it for that easy DIY project of insulating your house or apartment with very little effort. All I needed was a good pair of scissors and a tape measure. It was easy to measure, cut and install! It’s worth the price in saving on utilities for your home. I’d recommend getting some because it’s easy to install and take down if needed!

It works!keeps almost all cold out and all heat in.blocks all wind.10/10
This stuff is amazing!!!!10/10 was super easy to wrap my trailer with cuts easy but very strong.keeps out all wind and most cold better then anything else I’ve tried..(I’ve tried double thick plastic on inside and out…)and this is 10x better and easier.and it goes a long way I measured and everything and it went close to double what I had expected so you also get more then your think.if you live where there’s winter this stuff is a no brainer do yourself a favor get it and thank me later

Wonderful chicken coop insulator
Used to insulate chicken coops during cooler weather here in South Carolina and it worked great! Much thicker than other brands, is not flimsy, worth the extra bit of money for the thickness. Definitely recommend.

Very helpful. We really like it. It does what it's supposed to do.
This has worked great this entire summer. We shall see what it looks like next summer. But it has been extremely helpful keeping the heat out of my travel trailer ✨✨✨✨

Love it- insulated my garage - easy to cut and implement!
I used this to insulate my garage and it is awesome! It is easy to cut and made a big difference in our garage- I also used “great stuff” to seal all the holes and replaced the frame outside. Came just in time for the snow storm !! Easy to cut and great quality - you have foil on both sides with foam in the middle ! And it looks great ! Got the aluminum foil. You can also get double sided tape to tape it to the garage door so you have some space between the garage door and insulation . Would highly recommend it. I will be using it in our outer shed a bit later !

Really happy with this insulation!
I have a garage fridge that shuts off sometimes in the winter. I bought this insulation to cover the fridge and protect it from the cold. I’m very happy with the quality! I read reviews with other similar insulation and people complained about them being delivered with fold creases, being too thin, and being shorted with the measurements. This was delivered in a roll so there were no creases and it was measured perfectly. It was also a nice thickness and easy to work with. My fridge is not super large and there wouldn’t have been quite enough to put any on the front since I did cover the back (minus the small circulation area at the bottom). I didn’t want it to be on the front of the fridge anyway though. This isn’t a perfect solution for the garage fridge shutting off in the cold because I still needed to install a little thermostat heater thing, but this helped a lot. It’s also less bulky and instrusive than some of the premade fridge covers.

Great stuff!
This truly is amazing stuff! I had tried another type of room darkening film last year and it was worthless. So I was hesitant to buy this, but I got it, put it on the slider that the sun beats on in the evenings and RAISES house temps sooo high, even with an AC! It gets 115° to 120° here. IT REALLY WORKS!!! Keeps the kitchen and den at a decent temperature.... so glad I found it. Real easy to apply also. I'm a 67 yr old woman alone. You do need a tape, but not much. I got gorilla tape and it did the job! I'll be able to take it down at the end of summer & put it up again next year.
