Do ICFs promote mold or mildew growth?
EPS is an inert, organ­ic mate­r­i­al. It pro­vides no nutri­tive val­ue to plants, ani­mals or micro-organ­isms. It will not rot and is high­ly resis­tant to mold and mildew.
Is EPS the same as XPS?
No, these insu­la­tion prod­ucts are quite dif­fer­ent. EPS is closed cell expand­ed poly­styrene, while XPS is a closed cell extrud­ed poly­styrene. The prop­er­ties, appli­ca­tions and costs of each are quite dif­fer­ent. The major­i­ty of ICFs are man­u­fac­tured with EPS.
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.
