I know this product is for home construction but I have used this product for every Vacation Bible School project we have at my church. It cuts like butter, allows me to build depth why hot gluing pieces together and paints wonderfully. Plus the children love what I can create! Who knew Lowe’s was an art store as well. LOL

Sound Enclosure
Would RecommendI bought this to make a sound enclosure for my loud inverter generator. It cut the noise in half, very satisfied with the product and it was easy to work with.

Foam to Insulate Garage Doors
Would RecommendI purchased the foam to cut into sections and fit it in my garage doors for insulation. It has a rating of R5. I was able to wedge it in there and not use any glue or tape. So far it seems to be cooling it a bit.

You can get better material to use other than this
The material is rigid and breaks really easy. After cutting it to the length you need, you have lots of small particles of foam flaking off and making a mess.
