Understanding EDL: Engineered dimensional lumber is manufactured by bonding wood strands or veneers with exterior-grade structural adhesives under intense heat and pressure. This controlled process ensures predictable shear strength and eliminates natural defects like knots and wane, resulting in minimal warping or twisting. EDL allows contractors to frame wider openings, support heavier floor loads, and build tall walls that remain perfectly plumb.

Popular engineered wood products for your structural framing needs:

• Glulam (Glued Laminated Timber): Beams manufactured by laminating dimensional lumber lengthwise. Ideal for long roof spans, vaulted ceilings, and heavy load-bearing structural ridge beams.
  
  
• LVL (Laminated Veneer Lumber): Constructed from thin wood veneers, offering exceptional strength and dimensional stability. LVL is the industry standard for garage door headers, window lintels, and carrying beams.
  
  
• LSL (Laminated Strand Lumber): Formed from wood strands bonded with adhesives. LSL is highly stable and cost-effective, commonly used for ultra-straight wall studs, sill plates, and headers.
  
  TimberStrand LSL Rim Board is a specialized engineered product designed for the perimeter of floor framing systems. It provides exceptional vertical load transfer and dimensional consistency.
  
  Popular applications for TimberStrand LSL Rim Board include:
  
  
  • Residential and commercial floor framing
    
    
  • Lateral load transfer in roof systems
    
    
  • Tall wall framing applications
    
    
  • Beam and header supports
    
    
  • Rim boards for structural decks and porches
    
  
  
• I-joists: Pre-fabricated floor joists featuring solid wood or LVL flanges and an OSB web. They provide a lightweight, rigid floor system capable of spanning further than traditional dimensional lumber.
  
  

Professional installation tip: When framing floor systems, it is critical to match the exact depth of your LSL rim board with your I-joists to prevent subfloor deflection and ensure continuous load paths to the foundation.
