Are there different types of Expanded Polystyrene (EPS)?
EPS is list­ed basi­cal­ly under four prop­er­ty clas­si­fi­ca­tions – Type I, II, III and IV. The char­ac­ter­is­tics are based on the den­si­ty of the mold­ed foam which defines the prod­uct type. Fox Blocks ICFs are man­u­fac­tured as a Type II EPS with a den­si­ty of approx­i­mate­ly 1.5 pounds per cubic foot.
