We ended up with more insulation than we needed to build our shop/greenhouse. We have at least four full rolls of R-25 or R-15 which are five feet across. They have been barn stored for 2 years. Also a number of broken rolls which we bagged. They have been under tarps and out of the elements.
They are free for anyone who can use them. You will need your own truck to pick them up. The bigger rolls are heavy. You will need to load them yourself.
