PWT Focused on EWP
IWP is proud to partner with PWT, offering a wide range of Engineered Wood Products.  As one of the largest EWP manufacturers in the US, PWT is committed to  products that make a difference.  PWT I-Joists are more versatile than open web floor trusses and more uniform and dimensionally stable than lumber.

I-Joists can be trimmed on the job site, and wider flanges ensure that the floors you build are sturdy and stable.

Benefits include:

  • Quick Installation: Weighs less than traditional lumber.
  • Cost-Effectiveness: Long lengths allow ceilings and floors to be designed with fewer pieces.
  • Peace of Mind: Less likely to split, shrink, twist, warp or bow.
  • Durable Design: Larger nailing area and increased stability.
  • Sustainability: Wood sourced through programs certified under the Sustainable Forestry Initiative(r) and PEFC International Standards for Chain of Custody.
  • Warranty: PWI Joists are warranted to be free from manufacturing errors or defects in workmanship.. See complete warranty details for more information.

*PWT Series features design values equal to or greater than the LP product it is replacing. PWT I-Joist series ending in “S” indicates a solid sawn flange. PWT I-Joist series ending in “L” indicates an LVL flange.
