I seen it used in new milk barns out here with great results, easy to clean, light weight, easy installation, durable, comes in various thicknesses, ......but not cheap.Trusscore is so easy to install, I would only need to stop my grow about an hour to do the ceiling. Conventional walls can get wet and grow mold and mildew if I slip on my environment, not so with FRP sheets or Trusscore. Easy as sin to pick up and bring home and all the way around easier for my carcass. I fist seen it used in a licenced outfit and I was sold. Stuff is tuff and doesn't need paint. I'm happy with my space but feel like it's time to move along from my prohibition setup.
