There are a few different kinds of foam board insulation diyers should know about.

Expanded polystyrene foam board insulation waterproof.

Kingspan insulation r 3 common. Each type is used in a variety of applications and under conditions where resistance to water and moisture is critical. Expanded polystyrene also referred to as eps white board and bead board has the lowest r value of the three rigid foam board insulation types but is the most economical and versatile it can be used anywhere insulation is needed. It performs well as insulation for garages pole barns basements and crawl spaces.
