Foam Insulation board
Would RecommendIt does a nice job and is easy to work with. It was easy to cut to size with a pocket knife. Purchased to put on all four sides of a bee hive to help insulate them during the extremely low temperatures. I’ll let you know in the spring if it helped them live thru the winter.

Great product for basement insulation
Would RecommendWe purchased this to fill in a stud bay, where waterlines will be coming up from our Rockwall, old farmhouse, crawlspace, it is very easy to cut with a razor and the desired insulation we needed. We also used it for insulating our basement, great product.

Product was not the issue
Would Not RecommendIf you let Lowes pick your product, expect it to be in terrible condition and not the best pieces on the shelf. Do not use online ordering for things that need to be hand picked by you.
