its insulation board

holds its shape, easy to cut, and great for making halloween decorations

pricey but worth it

New construction home and we did not put vents in our crawlspace so using foam bosrd to pass insoection. I bought 40 sheets and could have a better product to work with. Grab a straight edge and score it with a utility knife and snap it like drywall. House stays 70 and crawl space stays around 60 with the insulated walls.

depends which branding you get
