Engineered Flooring Systems

The residential TJITM manufactured byTrus JoistTM is becoming the standard in floor construction. Yes, those engineered I-joists are quickly becoming the norm. While 2X10s and 2X12s are still specified and used in residential construction and remodeling jobs, they are not what contractors use most of the time, anymore.

When the construction industry figured out they were getting their money's worth every time they purchased this new engineered lumber, they kept using it. They were getting the same size lumber in every piece they bought and they knew they would be able to build a better structure.

Contractors like the wider nailing surface, (typical TJI chord width is 13¼" while 2x10s vary from 11¼" to 11½" in width). Contractors also love the long lengths: TJIs are stocked by retail lumber dealers up to 60' 0" long and they consistently order 28', 32', 42' and 48' lengths. This feature gives them the ability to put down one joist across all the bearing beams or walls versus handling numerous pieces of 2X material. The continuous span feature of the TJIs also stiffens the floor system due to the one-piece continuous span construction practice.

The best feature an engineered I-joist brings to the contractor's building practice is no shrinkage once the product is installed. Trus Joist uses this feature to pass on their "Silent Floor" warranty to each homeowner who has the Trus Joist product in his or her home. Normal dimensional lumber shrinks and this shrinkage causes loose nail connections between the floor joists and the plywood subfloor, which, in turn, causes squeaks and floor pops.

The Engineered I-Joist industry is here to stay as more and more builders and remodelers switch their jobs to the more consistent, longer, and stable engineered I-joist.
