143: Why is foam such a great building material?

Foam is an incredible thermal insulator. For the price and size, it's about the best insulation material you can get. But many people are concerned about the chemicals and process used to manufacture polystyrene.

I spoke with Curtis VanDyke from RL Adams Plastics about what they're doing to make foam 'green' and therefore make it an even greater building material.
