This episode of the Fire Sprinkler Podcast is my conversation with Ray Fremont Jr. about General Airs new Vapor Shield technology. Vapor Shield is like a security blanket for your sprinkler piping that lines the piping with a 1 molecule deep barrier to protect the piping from corrosion. We discuss the history, industry it came from, and other applications for this, as well as discussing the rumours throughout the industry about it.
