This publication is designed for: architects, builders, contractors, designers
While lumber has been the traditional product used for rim boards, it is generally not compatible with the depth of the new generation of wood I-joists used in floor construction. APA Performance Rated Rim Board can be manufactured using plywood, oriented strand board (OSB) glulam or structural composite lumber (SCL).
This publication contains a guide to selecting and specifying APA Performance Rated Rim Board.
