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.

Relatively inexpensive
Would RecommendDid not use for insulation. But great for any project that requires cutting full size plywood. Easy with track saw or circular saw. Use on flat surface to lay down with plywood on top. Held together well with a quarter inch cut deeper than plywood.

The foamiest foam around!
