Choosing the right EWP for your projects: TJI joists, a type of I-joist manufactured by Weyerhaeuser, are engineered lumber that offers numerous advantages for your building projects. Made from precisely oriented wood strands and bonded with adhesives, they form strong I-shaped beams.

• Strength and Consistency: Engineered for consistent strength, TJI joists allow for longer spans and greater weight capacity compared to traditional solid wood.
  
  
• Efficient Installation: Lightweight and pre-cut in various sizes, TJI joists minimize on-site cutting, saving time and labor costs.
  
  
• Versatility: Available in long lengths, they offer more flexibility for open floor plan designs.
  
  
• Dimensional Stability: The engineered composition resists warping, twisting, and shrinking, resulting in floors with less squeaking.
  
  
• Less Waste: Pre-cut sizes minimize onsite cutting, reducing wood waste.
  
  

These I-shaped beams offer exceptional strength and stiffness for both floor and roof framing applications. They act as beams to support the weight above them, such as walls, ceilings, and floors. TJI joists are ideal for a variety of residential and commercial projects, including:

• Floor framing in houses, apartments, and townhomes.
  
  
• Roof framing for buildings with flat or low-pitched roofs.
  
  
• Open floor plan designs with large, open spaces.
  
  
• Basements and crawl spaces for added support.
  
  
• Decks and balconies.
  
  

The span capabilities of TJI joists depend on specific size, type, and spacing. Span tables from Weyerhaeuser or your local lumber supplier will indicate the maximum allowable span for different joist sizes and load conditions. While both TJI joists and floor trusses are used for floor framing, there are key differences:

• Construction: TJI joists are I-shaped beams, while floor trusses have a web-like structure with top and bottom chords.
  
  
• Strength and Span: TJI joists generally offer greater strength and can span longer distances.
  
  
• Applications: TJI joists are more versatile for both floors and roofs, while floor trusses are typically limited to floor applications.
  
  

TJI vs I-joists: TJI is a brand name for I-joists manufactured by Weyerhaeuser. So, all TJI joists are I-joists, but not all I-joists are TJIs. Other manufacturers produce similar I-joist products.
