The rated wall option is the result of a new fire separation requirement in the 2012 North Carolina Residential Building Code, which is outlined in full HERE.
Under the new code, any home constructed less than 5 feet from the property line is required to have a 1-hour rated wall, with openings on no more than 25% percent of the surface.
