Open-cell foam should be avoided in below grade or in flotation applications where it could absorb water leading to decreased thermal performance. Open-cell SPF has an R-value around 3.5 per inch and typically uses water as the blowing agent. Closed-cell SPF has an R-value of around 6.0 per inch and uses high R-value blowing agents. Closed-cell foam compared has higher strength, higher R-value, and has greater resistance to the leakage of air or water vapor.

Heat is transferred by conduction, convection, and radiation. A large fire is an example of all three. The ground for several feet underneath the fire gets hot. This is conduction. Another example is to heat one end of a metal bar. Soon the other end is also hot. The second heat transfer source is convection. Convection occurs because when a liquid or gas gets hot, it tends to rise above the rest of the body. Think of the smoke and flames rising above the fire. The third source of heat transfer is radiation. The fire’s heat you feel on your face is infrared radiation. Even though you are away from the fire, you can feel that heat. A thermos is made to minimize the transfer from all three sources.
