Exposed Pyrobar Gypsum Block Wall

Guess what, more Pyrobar. Apparently a popular construction material a few decades ago, Pyrobar gypsum blocks are shown here as the main substrate behind partially removed wall finish materials. Samples of the Pyrobar and its mortar were lab-anlayzed and determined not to contain asbestos in this facility. However, smudges of black-colored glue adhering the wall finishings onto the Pyrobar were found to be ACM.
