LP® SolidStart® I-Joists

LP® SolidStart® I-Joists are more versatile than open web floor trusses, and more uniform and dimensionally stable than lumber. They can be trimmed on-site, and long lengths allow ceilings and floors to be designed with fewer pieces, saving installation time. Build sturdy, stable floors with wider flanges. Benefits include:

  • Quick Installation: Weighs less than traditional lumber.
  • Cost-Effectiveness: Long lengths allow ceilings and floors to be designed with fewer pieces.
  • Sustainability: Wood sourced through programs certified under the Sustainable Forestry Initiative®.

HOW IT’S MADE:

LP® SolidStart® I-Joists feature an advanced design and tough build for superior performance:

  • Combines laminated veneer lumber (LVL) or finger-jointed sawn wood flanges with a web of oriented strand board (OSB) to produce an I-shaped structural member.
  • Both materials work together to resist deflection, bending stresses and shear.
  • LVL and MSR lumber flanges up to 3-1/2˝ wide for greater stability.
