Thanks again for the response and the photo. I was expecting the more inexpensive compressed fiber-board stuff. I'm replacing old flooring in my house, and I want to avoid anything like what you described. Sorry you had to deal with that. I worked with some formaldehyde containing (out gassing) material once. It was not fun. After I started developing nose bleeds we got that crap out of our lab and started using masks around it.
