What Are Engineered Floor Trusses?

Engineered floor trusses are structural components that engineers use to support floors in multi-level buildings when standard lumber is either undesirable or unfeasible. Engineered floor trusses usually span longer distances than standard flooring solutions and provide greater structural resilience.

Floor installation contractors use engineered floor trusses to build strong floors while leaving enough space in the building's floor cavity to install ventilation ducts, heating and cooling systems, and electrical fixtures. The primary benefit of using floor trusses is increased strength using smaller amounts of construction materials, leaving greater voids for fixtures to be installed in.

Some engineered floor trusses are adjustable, allowing floor installation contractors to build specialized solutions for angled walls. Engineered floor trusses may also feature strut webbing that eliminates the need to cut holes in the existing floor cavity, freeing up more space. Another costly structural element that engineered floor trusses eliminate the need for are compression blocks. Compression blocks are only necessary when the floor is designed to perform under the heaviest of load conditions. Additionally, certain engineered floor trusses can be trimmed and shaped at the construction site, eliminating lead times needed for carpenters to build customized floor trusses out of lumber and deliver them to the site.
