Why Insulate With Foam? This is the classic example of the insulating power of foam and a great illustration of the importance of air sealing the area you want to heat or cool.

The Foam Picnic Chest... |
Q. Which is More Important...Obtaining a Higher R-Value or Stopping Air Infiltration?
This is an extremely important question. Let's say, for example, that you put in the sodas and the ice in the foam picnic chest above, but didn't put the lid down tight. The ice would only last a few hours at best, and your drinks would probably be lukewarm (or hot) by mid-day on Saturday. What happened? The R-value didn't change...it's still an R-2! So why did the ice melt? Because you allowed air to leak into the picnic chest.
What should we learn from this example?
The efficiency of the picnic chest does depend on the insulating power of the foam (its R-value), but its insulating ability is somewhat irrelevant if you don't also control air infiltration.
The answer to the riddle, in our example is that CONTROLLING AIR INFILTRATION HAD MORE TO DO WITH KEEPING THE DRINKS COLD THAN THE R-VALUE DID!
What does all this have to do with your new house?
We think the same is true for your new home, and we believe that your experience with a foam picnic chest is the most convincing argument that you should insulate your new home with foam.
Why?
Because foam not only insulates extremely well, but it will also stop air infiltration far better than fiberglass products.
