In response to the folks who asked me to send them information about the tin ceilings...I have no affiliation with the company other than the fact we both are in the same town (Nevada). I have installed several of their tin ceilings and have found them to be very helpful. You can contact them directly at W F Norman Company, 220 North Cedar, Nevada, MO 64772. Tel is 417-667-5552. Ask for Mark. They've got a catalogue and will be glad to answer your questions.
