Use Floor Trusses to Save Time & Money!

When it comes to installing the structural support for floors, several options are available. Until recently, dimensional wood joists have been the go-to solution. That has changed, however, as two superior options have become widely available. Both I-joists and floor trusses offer distinct advantages over traditional wood joists. Lee Lumber stocks both trusses and I-joists from leading manufacturers in an effort to meet the myriad needs of its Chicago customers.

Truss Benefits

Floor trusses, unlike joists, are manufactured off-site according to the exact requirements of a specific project. Open-web floor trusses have a greater capability for carrying loads and can span greater lengths than traditional dimensional lumber. They also provide open areas for wiring, plumbing, and ductwork and thus do not have to be modified in the field. Floor trusses are both easier and faster to install than joists or I-joists.

Unlike joists, trusses should not be altered in any way once fabricated because they are designed to precisely match the loadbearing needs of a particular floor. All floor trusses are reviewed by a structural engineer to ensure that they meet both code requirements and a job site requirements.

I-Joist Benefits

Whereas trusses cannot be altered in any way, I-joists can be cut and altered in specific ways to allow for changes in plans that occur after the fact. Because I-joists are not custom fabricated for every job, there is no need to wait for design and production to be completed prior to shipping. For the most part, lumber yards can stock these items for immediate purchase. Though I-joists can span greater distances than traditional dimensional lumber, they are not quite as versatile as floor trusses. Learn More About I-Joist Floor Systems Here.
