Useful
Would RecommendIt was so miserably cold outside that I got this to line an outdoor cat shelter. It's easy to cut, bend and fold into shape and must've warmed up the shelter nicely as a cat moved in the next night.

Price is questionable
Would Recommendeasy to work with though its pretty amazing what bubble wrap infused with a thermal blanket cost these days. The R value is way out in left field its much lower than that. I used it on a new wall i built for the outside in a very old mobile home hallway that was always cold in the winter and hot in the summer and to add some noise blocking from a neighbors dog. Lets hope it does what it says and also blocks out more of the hours of barking from a dog.
Easy
