I have just purchased yellow pine tongue-and-groove lumber for the interior of my home. As I moved the wood in 16' lengths into to house to acclimate, I noticed the extreme heaviness of each piece. They are about 7/8" in thickness. My total accent wall is 9' by 14'. The wall is an outside wall (brick exterior). Does anyone have any advice on whether the total weight I am adding to this wall could be a potential hazard?
