Framing the Floor System

An engineered floor system with TJIs start the framing for the 2019 FHB House.

By Jason Black

We use an engineered floor system when we frame our houses. We want to provide the highest quality product for our customers, and building a silent floor with no bounce to it is one of the ways we do that. The Weyerhaeuser TruJoists we use to frame the floors are dimensionally stable and their depths are consistent. That makes for a flat, stiff floor system. The TJIs are easier for the guys on the crew to handle on site, and easier to drill for the plumbers and electricians, so we gain job-site efficiency as well.

Timberstrand LSLs span openings in the floor plan like this stairwell.

TJIs are lighter than equivalent dimensional lumber joists and easier for a carpenter to move around the site.

TrusJoist rim board is nailed in place to lock the joists in place.

Ready for subfloor. One advantage of the TJIs is that the joists are dimensionally stable and of consistent depth. This means a flatter base for the subfloor.
