Coworker told me about the time he heard an explosion in the middle of the night, went to check it out and it was their tiles exploding. He told me that apparently they had been laid with a non flexible adhesive and once the weather changed significantly (or maybe it was cold air con blowing on hot tiles can't fully recall) the expansion and contraction or thermal shock just caused some of the them to start exploding. Had to get the whole floor ripped out and relaid.
