Its not thermacole, its Armstrong ceiling. wall carpet material I am not sure how to define, I just went to my local wall carpet shop and selected what I found best fit for the room under my budget. Thickness is not more than half a CM. Nothing vibrates, no ceiling, door or equipment rack, only my recliner which I feel ..hi sam,nice ht build of yours,one question you have used thermocol for ceiling
