What is the difference between closed cell foam insulation and open cell foam insulation?
Closed-cell foam insulation differs from open cell foam insulation in the fact that closed-cell foam insulation has tiny foams cells that are closed and packed together. They are filled with gas that helps the foam rise. Open cell foam does not have this characteristic.
Glass or plastic what keeps water colder?
Metal - very good conductor of heat. Not a good insulator at all (Don't wrap cans in aluminum foil.) Glass - A little better resistor of heat energy transfer but still not great. Plastic - Depending on the exact material, plastic is probably your best bet. Especially if it's a foam of some sort; the air bubbles in the foam create barriers that heat energy has to cross to be able to escape.

Is firefighter foam better than water?
yes, because many modern fires contain chemicals and other elements that burn hotter, and are often not affected by water. foam works better because it is specifically designed to put out fires that are either not affected by water, or become more intense when water is added, much like grease fires that arise when cooking.
