It works

I have bought 4 of 48x100 rolls and 1 36x50 roll and will be ordering 1 more 48x100 to finish insulating a 40x8 HC shipping container. I used 2 layers of insulation all around, with a 2" air space between layers.I tried several different spray adhesives and tapes to secure it to the walls and cover air gaps. The winner was Gorrila tape. Works great... that knowledge takes the sting out of the price per roll.Most importantly, this stuff is awesome! I noticed a difference with the cold and the heat temps.I'm on my 6th order, so I have bought the product again!

Fast shipping

If you cut in long strips, ie. 8' or16 ' for a double wide door, there is not enough product to complete door. To complete door you must cut in the 48" legenth. Product doors fine

Great for the price

I used this product to insulate from the top of the basement walls to the sills. It was easy to cut and install. There has been a marked difference with no cold air entering the basement.

Makes a big difference

I have used this stuff in a variety of places in my house. It is very versatile for insulating.I put it in the space between the top of my basement walls and bottom of the main floor (inside). The furnace ran noticeably less the first winter (with fiberglass behind it).Because this comes in a roll, the closer to the middle, the more curled the product will be. Bending it in the opposite direction helps. Also, have a plan to secure it down as it will want to bend. Or, set something on top of it and lay it flat for a few days.The 20mm product is 3/4 inch thick and is best cut with a serrated knife or scissors.
