We installed this insulation in a new metal building last fall. It was easy to work with and easy to install on the walls. The ceilings not so much just because of the need to work over your head etc. This fall we have torn down the ceiling insulation and paid to have spray foam put in the ceiling. We could not keep the building warm and when we did get it warm, we had dripping from condensation. I asked for help and they did let me know that somehow we did not have all the holes filled and air was getting in from the outside. I'm sure they were right, but we were not able to fix this problem. I would say over all we are very disappointed in this insulation. I read all the reviews and everyone was so positive so I felt I needed to add a real life fail. Hopefully they will keep this review on the site for future people to read.
