Rimboard

Features and benefits:

Rimboard Flooring
  • Resists twisting, cupping, cracking and warping
  • Available in depths of 912", 1178", 14", 16" and 24"
  • 16' lengths reduce the number of joints and offer easy handling and installation
  • Each board is edge coated and the units are paper wrapped for protection against the elements
  • Units are minor bundled
  • Engineered to have the structural stength to transfer both vertical and lateral loads
  • Designed and manufactured for use as a perimeter board for floor and roof joists in residential and light commercial construction
  • Smooth stable nailing surface
  • No core voids and will not delaminate
  • Norbord's RIMBOARD has edgewise bending properties and can be used to span openings of 4' or less
  • Norbord RIMBOARD is also produced in other thicknesses. Please contact us for details.
  • Manufactured in accordance with ICC - ES AC124, Acceptance Criteria for Wood based Rim Board Products and APA Rimboard Plus
  • RIMBOARD is also available with FSC or SFI CoC certification.
    Forest Certificates are available in the “Forest Certification” section.

RIMBOARD from Norbord is a certified "Green Approved Product" for the National Green Building Standard

Installation

Installation A full 1-18" edge surface allows for quick installation with virtually no risk of splitting. Installation of RIMBOARDs requires 8d common or ring-shank nails.*

  • I-Joist - drive 1 nail into the top flange and 1 into the bottom flange
  • Plate - toe-nail RIMBOARD at 6" on centre to wall plates
  • Floor Deck - space fasteners at 6" on centre
  • Ledger - use 12 " lag screws and ensure they completely penetrate RIMBOARD. Please refer to building code requirements for number and placement of lag screws.
  • Starter Joist - when RIMBOARDs are used as starter joists to maintain the vertical loading, there are several installation options, such as blocking (maximum 24" o.c.), double up the RIMBOARDs, or place an I-JOIST adjacent to the RIMBOARD. Please consult your designer for the appropriate option and details for your application
    RIMBOARD is designed to span openings of 4' or less.
  • A larger nail size may be required by some I-JOIST manufacturers.

  • The tabulated values are applicable to Rim Boards when subjected to the normal load duration (10 years) and permitted to be adjusted for other load durations in accordance with the applicable code except for edgewise modulus of elasticity and compressive stress perpendicular to grain.
  • Allowable edgewise bending stress is applicable only to a span of 4 feet or less. The adjustment for volume effect is already included. For applications requiring a longer span over an opening, use glulam, I-joists, or SCL headers.
  • Allowable edgewise apparent modulus of elasticity.
  • Allowable edgewise shear stress, which is permitted to be increased to 270 psi for mat-formed panels such as OSB.
  • Allowable compressive stress perpendicular to grain based on 0.04-in. deformation.
