Certification Period and Installation Date/Period of Manufacture

Full disclosure - I am the Technical Information & Public Affairs Manager for GREENGUARD Environmental Institute. Lauren - contact SCS and ask them if they have a copy of the old certificate. If the product was certified they should be able to get you a pdf of the certificate. As GREENGUARD does, SCS may also have it listed somewhere on the product listing in their product guide how long the product has been certified - we call it the certification period, but they may call it something different. If that doesn't work, then I'm sure if you contact Steelcase directly they would have the independent test lab report that covers that period of time that would prove that the product passes the criteria.
