T&G | Shiplap Planks
Ship Lapped Planks are best suited to cover existing drywall or wall board. Being only 3/8" thick, they weigh 25% less then tongue and groove planks that are 1/2" thick. Elite Wide Planks are sometimes substituted for Beaded planks for wainscoting. They look great on walls, the sides of staircases and on ceilings.
