Wood paneling on inside roof between the roof bows and in-between the log posts on the inside walls, serves two main purposes: 1-Paneling offers a super professional, finished look. 2-Plus, if a load shifts or falls, these wood panels protect the outer alum skin from damage. A few years ago we started adding an alum panel kick plate along the bottom of the inside walls as well… just in case your crews want to get their kicks-on.
