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.

Ordered online and got damaged goods

I placed an order for 30 panels online and went to pick them up after receiving a message that they were ready. When I got there, they were not ready so I had to wait nearly 30 minutes for them to find them and bring them up to the loading area. After everything was loaded, I noticed that a batch was damaged by the forklift and told the employer about it. You can clearly see the damage by the forklift on the side of the boards. I was told that those were all they had and they could not change th...

Pickup was disorganized.

The product is fine. Easy to cut, and put in between the ribs of the shed. The pickup was not well organized. They were not ready for me, even though that the order was submitted about 4 days erlier. It took several people to determine that the material had not been pulled (even though the computer told me that it was ready and waiting). I loaded the panels in the back parking lot of the store, alone. Somehow, I don't think that the staff completed the sale, when I was there. Several week...

The instructions are on youtube.

I liked the ease of use. I cut it into several pieces to make a box to cover my generator. I then added sound proofing foam panels to the inside of the box to reduce the noise. It lowered the Db by 10 Db which is pretty huge when you're camping in the woods.

Bait and switch

Would Not Recommend

Wanted the r tech in the photo and description got poly pro instead. Their descriptions do not match one specifys its vapor barrier capabilities while the other says it has none.

Very fragile around the edges

The foam itself, which is exposed around all four sides, crumbles at the slightest touch. This makes both transport and installation more difficult and messy than it needs to be. Otherwise, this is a fine product which performs exactly as advertised and at a reasonable price point.
