XJ 85 I-Joists

Pre-Cut I-Joists

Indeed, the XJ 85 I-Joists from Georgia-Pacific are a popular product.  Builder magazine rated the product #2 on its Readers’ List of Favorite Products from 2008.  Not surprisingly, the precut XJ 85 I-Joists boast a number of attractive features.  The most obvious is how they are able to incorporate holes for ductwork without sacrificing stiffness and overall quality.

By allowing the ductwork to be run through the XJ 85 I-Joist, it can be kept out of the attic and within conditioned space.  This is important because it helps prevent any added heating or cooling load.  When ductwork is run through conditioned spaces, less energy is required to maintain the home at a desired temperature.  Less energy means there is a cost savings to the homeowner.

The XJ 85 I-Joists were designed to provide for a reduced installation cost.  The product is available in pre-fabricated lengths with pre-cut holes.  However, the joists are able to be trimmed on-site, as well.  The lightweight construction also contributes to its low installation cost.  The cost reduction is realized through less labor and callback costs.

The XJ 85 I-Joists are available in a series of products ranging from six to twenty-six feet long in two-foot increments.  In using engineered wood, homeowners can take pride in the fact that the use of this product is ecologically friendly.  Using engineered wood reduces the consumption of timber.
