Polyisocyanurate ("polyiso") and polyurethane are very similar, closed-cell foam insulation materials. Because both materials offer high R-values (R 5.6 to R 8) per inch of thickness, you can use a thinner foam board to achieve the required thermal resistance. This can be an advantage if you have space limitations.
Effective Insulation. Resistance to heat transfer is measured as R value. The higher the R value, the less heat is lost per unit of time. For example, a wall with an R value of 20 will lose half as much heat per hour as a wall with an R value of 10. In a house framed with 2x4s, the wall is 3.5" thick.
