Giải thích
Approved fireblocking includes 2-inch nominal lumber cut to fit, two thicknesses of 1-inch lumber, wood structural panels, gypsum board, and certain mineral or approved materials. Loose sawdust and thin polyethylene are combustible or ineffective, and unsupported batts alone are not accepted general fireblocking except where specifically permitted.
