We've Moved! Welcome to Our New St. Pete Headquarters on 49th Street Big news from the Florida Vapor Barrier family—we've officially moved into our new headquarters! After years of serving Florida's mobile home communities from our Largo location, we've outgrown our space. We're excited to announce that Florida Vapor Barrier now operates from a much larger facility on 49th Street in St. Petersburg. And trust us, you can't miss it. We're in the giant blue building.
