That’s a new word for me. No, my memory is black painted and sealed concrete or possibly granite or some stone.
As for ventilation, one of the windows on the 4th floor completely blew out of the wall, frame and all, due to win. It landed right on a girls desk. Thank God the girl got up to turn in an assignment or she could easily have been killed by the 84 inch window.
Engineer/custodian came up and reinstalled the window. All the kids were weary of that window.
