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.

Cooled off my garage door
Would RecommendCuts and breaks easy with utility knife, but makes one huge mess of Styrofoam ballies. If it were not for ehe extensive cleanup, I'd give ut a five.

Really changed the comfort level.
Would RecommendI insulated my entire metal garage with this and it made a huge difference in the comfort level. I can work all day and it doesn't get near as hot as it used to. In fact: It's quite comfortable with only a fan going.

Too Expensive
Would Not Recommend$30/ board is way too expensive. You’re better off using interior waterproofing and insulation if your basement is water proofed on the exterior already. Can’t believe we pay over $600 for foam boards in 2025.
Great insulation
Would RecommendEasy to work with, a little pain cutting this without making a mess, worked really well insulating my garage double wide door.
