Frequently Asked Questions

Helpful answers to frequently asked questions about our company and products.

What is rim board?

Engineered wood rim board is a structural component that works with floor or roof framing members. EWP rim board is manufactured to match the depth of wood I-Joists and LVL. A rim joist is a structural member that runs perpendicular to and is connected to the ends of floor or roof joists. The terms rim board and rim joist are often used interchangeably.

Engineered wood rim board products should be used with engineered wood joists. Solid sawn rim boards may shrink at a different rate than engineered wood products resulting in dimensional incompatibility. See WIJMA rim board position statement.

Warning: Drilling, sawing, sanding or machining wood products generates wood dust, a substance known to the state of California to cause cancer. Avoid inhaling wood dust or use a dust mask or safeguards for personal protection. California Health and Safety Code Section 24249.6.
