Expanded Polystyrene (EPS)

SIP Panels, as tested by the U.S. Department of Energy, have been proven to outperform conventional frame construction by at least 66% for energy efficiency. SIP Panels are 2-1/2 times stronger than conventional framing, cut the framing process down to approximately 1/3rd the time, and offer superior noise and weather isolation over traditional framing methods.

Expanded polystyrene differs from a similar product, called extruded polystyrene, in important ways. Extruded polystyrene is made using chlorofluorocarbons (CFCs), which are considered to be harmful to the balance of ozone in the earth's atmosphere. Expanded polystyrene is made without these compounds, making it more benign to the environment. Both products, however, can be recycled like all plastics.

EPS used for the manufacturing of structural insulated panels are strong, energy efficient, environmentally friendly and cost effective. The manufacture of EPS foam uses less energy than that used in the manufacture of competing alternatives.
