I see there has been some discussion regarding the instillation of Hardwood Floors on a wall, but the questions that I have doesn't seem to be answered. Would the weight of engineered pre-finished hardwood be too heavy for the wall? Would a flooring such as pine or bamboo be better because it is a lighter material? I am planning on installing the hardwood T&G method, 16" on center 8'x10' studded wall, also thinking of installing mdf/plywood onto the wall before putting up the hardwood (horizontally) just for extra support and a true flat surface. Some thoughts and insight would be appreciated.
