How far can an I-joist span?
Span refers to the length of the I-joist. The L/480 table with a 40 per square foot live load and a 20 per square foot dead load with a depth of 11 7/8 inches will give you spans according to joint weight. With these factors, the lightest joist will have a maximum span of 17 feet, 8 inches.
Do I joists need blocking?
Blocking panels are required at each end of floor joists not otherwise restrained from overturning by a band joist or rim board. Blocking panels are required between floor joists supporting load-bearing walls running perpendicular to the joists.
Do I-joists need bridging?
Bridging is sometimes required in floors or roofs when solid-sawn lumber joists are used. This addition provides lateral support to twisted joists to help maintain a vertical orientation. It also facilitates load sharing.
Do I-joists need support?
I-joists should be braced and nailed as they are being installed. Use correct joist hangers, blocking panels, rim boards and cross-bridging at joist ends. I-joist temporary bracing must be 1 x 4-inch minimum, at least 8 feet long and spaced no more than 8 feet on center.

How do I block an I-joist?
To make the blocks, I cut sections of I-joist 1½ inches smaller than the space between the joists, then nail a scrap of ¾-inch subfloor material to each end of the block [1]. This creates two large nailing fins. Calvin Cutts works from a ladder to install the blocks.
Is bridging or blocking better?
We think that metal bridging is much easier to install and accomplishes the same thing as solid blocking. Also, solid blocking seems more likely to cause squeaks because of all the extra joints and nails required for installation.

Cutting and Installing I-Joist Rafters
It’s always the prep work that takes time. WACTC construction-trades students spent a couple hours calculating the common rafters and making templates. After they headed back to school, I cut sample rafters and tried them out on the roof. The angles were perfect, and the length just needed to be trimmed down by 1/8 in.

What is an I joist roof?
I-joists make for a strong, flat roof, but you have to pay attention to the connections at the ridge and eaves. While many builders have incorporated I-joist floor systems into their standard construction, roof framing with wood I-joists remains somewhat of a mystery. Roofs tend to be more complicated than floors, ...
How to support joists on a ridge beam?
But whether you use a ridge beam or a bearing wall, there are two ways to support the joists at the upper end: with hangers or a beveled bearing plate (see ""). The important point to remember is that no birdsmouth cuts are allowed at the high end of the I-joist.
Do you need to engineer a connection between the floor and ceiling joists?
The loads are primarily gravity loads, which push down, not out, on the bearing walls. So there is no need to engineer a connection between the floor or ceiling joists — if there are any — and the rafter ends.
Can I use wood I joists on a roof?
Roofs tend to be more complicated than floors, so it’s natural that builders accustomed to stick framing might be cautious about using wood-I’s instead of solid-sawn rafters.
Do you need a bearing post under a ridge board?
There is no need for bearing posts under the ridge board, which is nonstructural. The roof loads are carried to the top plates of the bearing walls, where the floor joists, acting in tension, keep the rafter ends from spreading out. What you have here is essentially a truss, built on site.
