Span Chart
L/480 is the design criteria we recommend for the best performing floor
Features and Benefits:
-LVL Flange for superior strength and a squeak-free floor
-Capable of spans up to 32'
-Pre-notched holes for mechanicals
-Multiple depths and series for any application
-In-house design and engineering
-Long Spans
I-Joists can span up to a whopping 32' without support, giving custom home builders the ability to create open floor plans that customers demand
-LVL Flange
An LVL flange is critical for a high performing floor because it prevents squeaky floors in two ways. 1) the LVL flange holds fasteners better, preventing loose nails that cause squeaks, and 2) it will not shrink over time with the moisture change which is another common cause of squeaks
-Engineered for Consistency
All TJI Joists will be perfectly straight and will not twist, warp, or cup
-Allow for spacing for HVAC, Electrical, and Plumbing
Large holes can be cut in the webbing of TJI Joists, allowing for mechanicals to be easily run and installed. Joists can also be spaced wider than traditional solid sawn joists which allows for quicker and easier installation
-Fast and Easy Install
All TJI Joists are designed using patented software that designs a floor taylor-made for every home. This software creates a layout and specifies where every single framing member goes. When the material arrives on the jobsite, there is minimal cutting, and carpenters know exactly where every joist goes.

I have an addition that is to be built for a homeowner who wants I-joists. I&#;ve gotten MUCH conflicting info between my Lumberyard and the Big box stores as to the right size joist.
The big boxes are spec&#;ing Boise Cascade I-joists. The homeowner says they want to feel the floor as solid as possible with as little hint of deflection as possible.
The structure in question here is 20ft 6&#; long x 28ft wide. I plan to space I-joists 12 o.c across the width of 28ft for a total of 26 I-joists. I&#;m using 11 7/8&#; I josits. The span that they must span is of course 26ft 6&#; (this span includes the foundation wall, outside to outside).
The owner plans for carpet on the floor, maybe wood. A possible large typical aquarium, typical furniture and chairs (this is a Sunroom). The upstairs floor, which mirrrors the first, will be a master BR consisting of typical BR furnishings like a nice heavy bed set.
I&#;ve been told I can get away with a BCI 90 which is a 3.5&#; top/bot cord of the joist. I also been told I can do it with a BCI MINIMALLY, or that I can use a BCI . One places says I&#;m told by the others wrongly. One place says I MUST use a 3.5&#; cord. Other places say I must use web stiffeners.
Any opinions out there on who is right? One place claims the mfgr says I must use 3.5&#;. I don&#;t know who to believe. The price difference is almost double between BCI and BCI 90.
If at first you don&#;t succeed, try using a hammer next time&#;everything needs some extra persuasion from time to time. -ME
