What Customers Are Saying
The PolyPro Foam Boards provide effective insulation that is easy to install and suitable for DIY projects. Customers appreciated the 2-inch thickness, foil facing, and ease of cutting and shaping the boards. The insulation helped improve temperature and comfort levels in various spaces. However, some customers reported issues with damaged or defective boards, high prices, and excessive cleanup due to Styrofoam shedding. The R-value was also lower than competing products, and the boards may not be suitable for certain applications. Overall, the product is a decent insulation option, but customers should carefully consider their specific requirements before purchasing.

Would Not RecommendEasy for the DIYer to use. Using this foam board insulation in the walls with foil side towards outside of workshop. Studs are open on the inside of the workshop. Will cover with OSB once insulation all installed. Cuts easily with a jigsaw and fine-toothed blade. Tried circular saw and table saw with fine toothed blades, but not as easy to use. Foam board has enough "give" to allow slightly over-sized (1/8") pieces to be forced in between studs and then they will not move. TQ

Somewhat silly review ahead
Would RecommendOkay, I purchased 14 of these about two weeks ago to insulate my well house. To be honest, I ordered 3 too many. FYI, what I picked up has a completely different name, so don't expect the product to look exactly as pictured on Lowes.com. Mine say, "PolyPro" on them. What you're getting is truly 2" thick, 4' x 8' Styrofoam panels with silver Mylar on one side. It can be cut with most anything, but clean cuts are easiest with a table or circular saw. Whatever you use, it's going to make a mess. Y...

Lowe's carries both R-tech and PolyPro under the same item number, make sure to call and make sure it is R-tech before scheduling delivery.

Insulation for garage doors
Would RecommendThe product is good and worked fine for insulating my garage doors. However in the middle of the stack, there was one panel that has been cut about a foot from one in and then taped back together and shipped to me.
