Here is an age old riddle about Insulation
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 did not 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 did not change, it is 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 it's insulating ability is somewhat irrelevant if you do not also control air infiltration
A. 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.
Now that you are gaining an appreciation for the benefits of foam, let's see how applying it in your home can make it so much more efficient? You have just seen how well 1/8" of foam insulates. And you have seen a dramatic example of how well 1/2" of foam can both insulate and airseal. But here is the good news. In your home, we propose foam from seven to eleven times thicker than the foam in a picnic chest. Imagine the efficiency you can achieve with that much foam, both to insulate it and to prevent excess air infiltration. The result? A home that will be more comfortable and efficient and affordable to operate. And a home well prepared to cope with the energy uncertainties we are certain to face in the years to come.
