Double Bubble Reflective Foil Insulation (24 inch X 10 Ft Roll) Industrial Strength, Commercial Grade, No Tear, Radiant Barrier Wrap for Weatherproofing Attics, Windows, Garages, RV's, Ducts & More! .

I broke down & bought an air conditioner this summer. I didn't want to struggle taking it out for the winter so I bought a cover. I needed to provide some kind of insulation to keep the wind from coming thru the fins on the sides. This product is great! Easy to use and handle. It cuts with scissors and utility knives. I put it on the outside. It's flexible & light so I could bend it into the corners for complete coverage. Duct tape adhered well to it. I was able to easily cover any places wind might blow in, including the top, over the sash of the window. When I walked back into the room I could already feel the difference! No drafts! I also cut strips of it and duct taped it to the bottom of the screen door which is half glass, half metal. There's a huge opening under the door. Leaves come into the foyer and the cold wind blows in. Works great! It's flexible so it bends easily when I open and close the door and provides a perfect barrier. The door opens out onto the lawn (no concrete there) so with time the dirt had packed down creating a "smile shaped" hole under the dirt. This product was the perfect solution!

I went from feeding 1 homeless hungry cat to having her show up one day with 3 of the cutest tiny kittens. They were so sweet and polite. They weren't playing or scampering around, they were sitting next to momma looking at my door. When I opened the door to bring food out they didn't run, it was like mama cat told them what to do. I put the food down and said "ok go eat" and they did. 3 years later I still feed 1 of the babies and HER BABIES. AND I have some newcomers who need to eat. Anyhow... I bought some rubbermaid 50 gallon bins and used this insulation to make shelters for them. This is very easy to work with. It cuts easily with a scissors and I use duct tape to keep it on. I put warming mats inside but that's another story but I actually got the idea to do this from another review on Amazon so I figured I would pass this idea on for other animal lovers.

Used this to insulate our outdoor cat houses. attaching it to the walls with industrial Velcro, as opposed to an adhesive & popping an outdoor pet heating pad in the bottom. It was easily cut it with kitchen shears as it is very flexible, almost like a crunchy, reflective, bubble wrap. Though, I’d read on someone else’s review they’d used double-sided tape, I found that application insufficient for my needs and cold climate. Shipping was a bit slower than what we’ve gotten spoiled to. All around a great product. Could see its uses in an RV setting.

Kept hot air out and cold air out heater and AC doesn't have to work so hard also good for keeping light out

Used in a drafty single pane window, really made a difference but no light gets in, so it's great for a temporary winter protection and savings on heater electric bills, so it pays for itself. I'm already looking at this roll for a million uses, it is easy to cut and firm enough to push in tight places and still keep it's shape. You can use it anywhere you want, overall glad I got it.

I got this to insulate my outdoor cat’s nice little house, which is weatherproof (not resistant, weatherproof) and I use straw on the bottom underneath the layers of blankets for him. I put my hand inside when the temps were single digits, bitter cold. That little house was as warm as my house! The insulation is easy to cut and fit, and I used a roll of insulation tape which sticks completely so there’s no gaps for cold air and wind. This isn’t adhesive, btw but it’s not supposed to be. I covered the front of his house with towels to shed rain and an old shower curtain weighted down to keep our wind and rain. He’s got a covered, protected entrance that way. Plenty on one roll of insulation with leftovers. His house is roughly 17” x 16”. We are very, very happy!

As an anemic, I don’t know why I live where the air hurts my face but it is what it is. Delivery was fast, used it to cover my Air conditioner because I did not want to take the whole unit out. Easy to set up and I used duct tape to seal it. Used scissors to cut around the corners and it cut easily. Overall good quality, hopefully it blocks the cold air out.

I purchased this to go camping in my car. I cut the size needed for each window and put the product in the window at night. They kept it quiet, and actually warmer in the car. They fit right up in the window and used them over and over. It was easy to cut and store.
