Thermal insulators work by trapping bubbles or pockets of gas inside a foam structure. When these cells of gas are filled with moisture, there are significant losses in insulating efficiency. The thermal conductivity of water (at 10 &C) is 0.5 kcal m 1 h 1 &C 1 and that of ice (at 0 &C) is 2 kcal m 1 h 1 &C 1 (about four times the value of water).
