RigidRim Rimboard

Overview Properties Design Guides Software Tools Sustainability

RigidRimRoseburg RigidRim RimboardRoseburg RigidRim® Rimboard is used for perimeter framing and load transfer. To manufacture our EWP products, we use fast growing, under utilized, and less expensive wood species; therefore, large old growth trees are preserved. As a component of the Roseburg Framing system®, Rigidrim® OSB and LVL rimboard allows contractors to quickly frame the perimeter of their floor system and is one of the most cost effective methods to properly transfer vertical and horizontal loads around the I-joist and directly into the supporting walls.

Roseburg’s RigidRim is dimensionally stable and resists shrinking and warping. It also provides a smooth nailing surface for the attachment of exterior sheathing, siding and ledgers.

When And Where You Need It

Roseburg RigidRim® Rimboard is available throughout North America at some of the largest and most respected wholesale distributors and pro-yards. We encourage you to contact one today to get more information on Roseburg's RigidRim® Rimboard.

All RigidRim rimboard products are manufactured in accordance with ANSI/APA PRR 410 Standard for Performance-Rated Engineered Wood Rim Boards which meets or exceeds the requirements given in the ICC-ES Acceptance Criteria for Wood-Based Rim Board Products, AC 124.  Furthermore, the 1.3E LVL and 1-1/4” Ainsworth Durastrand® rimboard products have ICC-ES code reports (ESR-1210 and ESR-1053 respectively).  See Table 1 below for RigidRim rimboard design properties.  All RigidRim rimboard products have been tested in the edgewise bending orientation and therefore may be designed for applications to support loads over window and door openings.  See Table 2 below for allowable design properties for edgewise bending.  See Table 3 below for allowable uniform loads for specified spans (see APA publication W345 Performance Rated Rim Boards® for additional information).

Design Properties

RigidRim Design Properties



This 60 page Roseburg EWP Design Guide contains information on Roseburg's RFP-KeyBeam®, RFP-KeyColumn®, RFP-KeyPlan® & Smartframer software. It also has design information for RFPI Joist, I-Joist details, RigidRim Rimboard, RigidLam LVL Headers, Beams and Studs and I-Joist & LVL framing connectors.

The various charts and tables in this guide are based on accepted, typical residential loading conditions, on center spacing, deflection criteria and/or spans. This published information allows the end-user to identify and install properly sized Roseburg engineered wood products without the need for specific design or engineering calculations.



For applications with longer spans, wider spacing, and higher loads, Roseburg manufactures RFPI® 700 and RFPI® 900 -- with depths of 18", 20", 22" and 24". This 20-page Roseburg Design Guide contains design properties, allowable load tables, framing and connection details, web-hole specifications and everything you need to work with our deep I-joist products.
