The accel-E™ Steel Thermal Efficient Panel (S.T.E.P.) wall system has been Certified for Indoor Air Quality by the GREENGUARD Environmental Institute. In order to be GREENGUARD Indoor Air Quality Certified®, the EPS insulating material in the S.T.E.P. panels was screened for more than 10,000 different volatile organic compounds, and found to emit the fewest possible chemicals into the indoor environment. By using products bearing the GREENGUARD Certification mark, architects, designers and specifiers can be assured these products have been independently verified to meet some of the most rigorous chemical emissions standards in the world

The GREENGUARD Environmental Institute (GEI), a non-profit American National Standards Institute (ANSI) Authorized Standards Developer, oversees the GREENGUARD Certification Program[SM].
