The IB Solid Sawn Wood I Joist Advantage

Builders want building products that make the process of building easier,faster and more profitable.

International Beams (IB) Solid Sawn Wood floor and roof framing I Joists give builders what they’re looking for.

Plus homeowners appreciate the stiff, sound floor IB I Joists provide.

There are many advantages to building with IB I-Joists. For one, traditional framing lumber (2 x 8 and 2 x 10) is prone to splitting, warping, shrinking, bowing and twisting, often resulting in floors that squeak and expensive callbacks.

IB engineered wood products, including its Solid Sawn Wood I-Joists are manufactured under climate controlled conditions resulting in dimensionally stable lumber with low moisture content which virtually eliminates these problems. Combine this advantage with those listed below and you'll quickly appreciate why IB I Joists are becoming the preferred engineered floor joists.

Advantages and Benefits

  • IB I Joists lightweight construction, ease of handling, strength and long spans result in lower overall labor and material costs compared to solid lumber.
  • Wide flanges provide a larger gluing and nailing surface for floor and roof sheathing.
  • Our software calculates the number and type of floor and roofing I Joists required for your job.
  • Traditional framing tools and fasteners make installation of IB engineered wood I beams fast and easy.
  • Compared to traditional framing lumber, IB I Joists span longer distances, allowing the joist spacing to be wider, so there are fewer pieces to handle and install.
  • IB I Joists are more uniform in strength, stiffer and straighter than regular framing lumber.
  • Openings can be strategically cut in the I Joist web to allow for wiring, duct work and plumbing.
  • FSC certified. LEED, Green Globes and National Building Standard Green Point credits are attainable.
  • Ecologically friendly. It's The Green Building Solution.™
  • Order exactly the number of roof or floor joists you need, thereby reducing cost and eliminating waste on the job site.

The full product line of IB I-Joists (9.5" to 24" depths and lengths up to 52') allow you to maximize the structural performance of floors and roofing, save time and money, yet deliver a higher quality floor or roof.

Engineered for high performance, manufactured to uniform dimensions and backed up by one of finest technical and sales teams in the industry, IB I Joists simply make designing and building with engineered wood easier, faster and more profitable.

Enhanced Performance

Enhanced Floor Performance

International Beams broad range of I-joists provide builders with flexibility in joist selection, spacing and construction detail. Although all values contained in the International Beams Design Manual meet or exceed code requirements, long-term floor performance (comfort) should be considered in all construction projects.

The following options will further increase the floor stiffness:
  • Using floor deflection of L/480 instead of the code minimum of L/360.
  • Gluing and nailing the sub-floor to the joists.
  • Attaching gypsum board to the bottom of the floor.
  • Decreasing the joist spacing by one increment based on allowable span.
  • Using full depth I-joist blocking panels at mid span between floor joists.
  • Using deeper joists.
  • Using a thicker sub-floor, i.e. 3/4" or 7/8".
  • Attaching strapping at 16" o/c.

Handling

Storage, Handling and Safety Guidelines

To assure optimum performance and safe handling, International Beams I-joists must be stored and applied properly. The following guidelines will help protect joists from damage in storage, during shipment, and on the construction site, and protect the installer from jobsite injury.

Storage and Handling

1. Store, stack and handle IB I-joists vertically and level only. 2. Do not store IB I- joists in direct contact with ground and or flatwise. 3. Protect IB I-joists from the weather, and use stickers to separate bundles. 4. When handling IB I-joists with a crane on the job site (“picking”), take a few simple precautions to prevent damage to the IB I-joists and injury to your work crew.
  • Pick IB I-joists in bundles as shipped by supplier.
  • Orient the bundles so that the webs of the IB I-joists are vertical.
  • Pick the bundles at the 5th points, using a spreader bar if necessary.
5. To further protect IB I-joists from dirt and weather, do not open bundles until time of installation. 6. Take care not to damage IB I- joists with forklifts or cranes. 7. Do not twist or apply loads to the IB I-joist when horizontal. 8. Never use or try to repair a damaged IB I-joist.

Safety Tips

A. IB I-joists are not stable until completely installed, and will not carry any load until fully braced and sheathed. B. Do not allow workers to walk on IB I-joists until joists are fully installed and braced, or serious injuries can result. C. Never stack building materials over unsheathed IB I-joists. Stack only over beams or walls.
