Features

Polystyrene foam is a sturdy but lightweight foam that’s very popular for personal projects like arts and crafts, as well as for commercial uses like geotechnical filler in construction. Surprisingly strong, EPS’s unique closed‐cell structure offers excellent resistance against moisture and water vapor, and will not rot, mold, or mildew. Available in sheets, EPS has a superior R-value which makes it an outstanding insulation product in homes and hot tub covers.
