SEALTECH 3mm Reflective Insulation Roll - Premium Foam Core Radiant Barrier for Energy Conservation -Commercial Grade Soundproofing Thermal Shield for Indoor and Outdoor Use (48" X 25')

Haven't actually used it yet, but this is clearly a strong and well-made product and a definite step up from the air bubble type that is cheaper and similar in application but is neither as solid or as highly rated for sound or RV factor.

I used this for our two window air conditioners. It was very easy to cut to the right size, looks great, and seems to provide good insulation. It is a very good deal for the price, better than any other insulation roles I could find for window air conditioners. Definitely recommend this item.

This us wonderful insulation. I used it under floor tiles Works great.

It is keeping the house much warmer

Used to insulate outside cat house for feral cats… great product!

Used to double down on two feral cat houses...Thank you Walmart

It's what i wanted but didn't get it after a week later than the date said. they let me know on the date of arrival that it was going to be late. i could have been happy if they would have given me a discount but nothing

It is very thin and flimsy, wish I would have gotten the 10mm. I live in a mobile home with double pane windows, so I wanted it to put in between the two windows instead of trying to figure out how to attach to inside. I thought I could just cut to size and slide it up between the double panes, but so flimsy, had to get foam board and cut to size to keep in place. Then I used two pool noodles, one on each side to secure it in between the windows, one on each end of the thermal insulation. Those fit the width between the windows perfect. And holds it in place

great product. took forever to get delivered though

This product is fine, it was the wrong product for me. It came all folded over and I wanted to use it for skirting…. It had a lot of folds and didn't want to lay flat.
