Product Description

14" RFPI-40 I-Joists are supplied through our Boise, Idaho lumberyard for framing jobs throughout the Treasure Valley. Designed with wide 2-5/16" flanges, this 14" series delivers extra lateral stability during installation and a wider subfloor fastening target. Engineered wood layers bonded with structural resins ensure that every joist remains stable, avoiding the warping common in deep dimensional lumber. This series serves as a direct equivalent to Weyerhaeuser TJI-230 and Boise Cascade BCI-6500.

Specifications
  • Brand: Roseburg Forest Products
  • Depth: 14"
  • Flange Width: 2-5/16"
  • Series: RFPI-40
  • Material: Engineered wood with solid OSB web sections
Common Uses
  • High-performance clear-span residential floor platform layouts requiring high vertical load transfer capacity.
  • Deep roof framing purlins and flat roof rafters carrying heavy wind or equipment loads.
  • Perimeter joist tracking and closure framing matching 14" deep structural systems.
Contractor & Builder Notes
  • Standard Hangers: Face mount IUS2.37/14 top flange ITS2.37/14.
  • Stable Wide Target: The 2-5/16" wide flange speeds up panel placement and prevents edge fasteners from blowing out.
  • Excellent Rigidity: Wide flange profile reduces twisting during installation, keeping framing crews moving safely.
  • Web Stiffeners: Ensure specified wood web stiffeners are attached tightly at heavy bearing walls per layout plans.
