DOW products has lots of information on their site about different foam board products here. I also recommend you read a recent article about Open Cell Vs Closed Cell Foam products to understand the differences between the two product types. Expanded Polystyrene Foam. Expanded polystyrene foam (EPS) is the cheapest and least used foam board product on the market.
This product typically has an R value of 3. Expanded polystyrene insulation is similar to the foam used for packing “peanuts” and it’s typically used for insulated concrete forms also knows as ICF’s. It is also sometimes used on commercial buildings for roof and wall panel insulation which is typically sandwiched between light gauge metal. Cost = Cheapest of the foam insulation boards.

Polyurethane and polyisocyanurate are both closed- cell foams. They contain low- conductivity gases in the cells (usually one of the HCFC or CFC gases.) The higher R- Values (R 7. This can lead to a couple of disadvantages including: off gassing of HCFC or CFC gases, and reduced R Value over time as the gas escapes.
