Rim Board ®
APA Performance Rated Rim Board is a specially designed component that is engineered to work in concert with wood I-joists to deliver a complete engineered wood framing solution.
An Integral System Component
APA Performance Rated Rim Board fills the space between the sill plate and the bottom wall plate, or between the top plate and bottom plate in multi-floor construction. In addition to filling the void, Rim Board is an integral structural component that transfers both lateral and vertical forces. To function properly, the Rim Board must match the depth of framing members, and conventional solid sawn lumber typically does not match the new generation of wood I-joists.

Quality, Consistency and Reliability
APA Performance Rated Rim Boards can be manufactured using plywood, OSB, glulam or LVL. Depending on the product used, building material suppliers can deliver APA Performance Rated Rim Boards in lengths up to 24 feet. These engineered wood Rim Boards have greater dimensional stability, higher strength, increased structural reliability, more consistent quality and a lower tendancy to check or split than sawn lumber.
