Closed-cell foam

Revision as of 22:05, 26 April 2006

In Closed-Cell Foam, most of the cells or bubbles in the foam are not broken; they resemble inflated balloons or soccer balls, piled together in a compact configuration. This makes it strong or rigid because the bubbles are strong enough to take a lot of pressure, like the inflated tires that hold up an automobile. The cells are full of a special gas, selected to make the insulation value of the foam as high as possible. Closed-cell foam has varying degrees of hardness, depending its density.
