TrimJoist’s strut web design completely eliminates the subcontractor's need to cut holes. Thus, the valuable floor cavity space is available for plumbing, electrical and duct work. No more drop down ceilings. Great in basement areas!
Unique TrimEnds allow the truss to be trimmed on the job site for an exact fit. Other trusses typically cannot be adjusted for site conditions that may not be exactly as expected. TrimJoist is also great for angled walls.
The TrimJoist features a 3.5-inch flange on both the top and bottom for simpler subfloor construction. A wider surface area allows more glue to resist the shearing action between the joist and subfloor. Also, more nails hit their mark thereby reducing the likelihood of squeaks.
With 23/32-inch thick OSB in the TrimEnd sections, you'll rarely ever need to use compression or "squash" blocks. Only under the heaviest of load conditions is additional blocking required.
The TrimJoist design spares the “old-growth” forests that are necessary to produce all traditional wide-board joists. In addition, its engineered strength allows for longer spans and greater on-center spacing. This not only reduces construction costs, but also can reduce the board footage of wood fiber required by up to 12% over traditional joists.
