The Exceptional Properties and Benefits of I-Joist

  • Invented in 1969, the I-joist is an engineered wood product that has great strength in relation to its
           size and weight. The biggest notable difference from dimensional lumber is that the I-joist carries
           heavy loads with less lumber than a dimensional solid wood joist.

  • As of 2005, approximately 50% of all wood light framed floors used I-joists.

  • I-joists were designed to help eliminate typical problems that come with using solid lumber as joists. The advantage of I-joists is they will not bow, crown, twist,
           cup, check or split as would a dimensional piece of lumber. I-joists' dimensional soundness and little to
           no shrinkage helps eliminate squeaky floors.
