What is Modified Expanded Polystyrene (EPS)?
The expandable Polystyrene resin used in ThermaSteel panels is modified by the supplier of the raw material to resist flame spread and is in full compliance with the ICC building codes and has received HUD approval. The use of EPS as rigid thermal insulation gives the ThermaSteel panel the following advantages: • R-Values are consistent and stable due to the closed cellular structure, which contains stabilized air. • Components are rigid and lightweight. • Contains no CFC’s or HCFC’s. There is no off gassing. • Contains no formaldehyde • Resists fungus, decay and moisture gain • Will not rot – highly resistant to mildew • Environmentally safe. • Lessens risks of cancer and of respiratory and skin irritations from certain other types of insulation. • No food value for termites and other common wood eaters.
