Are I-joists cheaper than lumber?
However, the low cost of producing fabricated wood products has made I-beams nearly as cheap as dimensional lumber. Also, engineered joists can be made to nearly any length – 2x10s only go up to 16'. You can find 20' or even 24' lengths, but be prepared to pay.
Are I-joists cheaper?
We generally supply I-joists to the larger housebuilders, due to their lower costs compared to Posi-joists. Engineered I-joists are predominantly used for floors but in some instances, can also be used to create flat roofs for both residential and commercial buildings.
How far can Ai 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.

What can I use instead of I-joist?
You can go the traditional floor framing method with dimensional lumber, otherwise known as 2×10's or 2×12's. Or, you can use a manufactured floor truss, which is typically made up of 2×3 or 2×4 members and are designed and built by your local truss plant.
What is stronger LVL or I-joist?
The LVL keeps the I-joists in place and gives additional support for the floor. Like the I-joists, the LVL will not bow, crown, or split. The composition of the wood is much stronger than traditional lumber, and therefore can be relied on more.
What are the strongest floor joists?
Since knots and other defects weaken wood, higher grades of lumber (designated as clear, select, or #1) are considered stronger than lower grades. Higher grades of lumber, however, are also much more expensive. Lumber graded as #2 is the most common choice for floor joists and other framing lumber.
What is better I-joist or floor truss?
Floor trusses can span farther between bearing points than I-joists, allowing for larger open rooms. This also reduces the need and cost for extra bearing posts, beams, and footings. Floor trusses have built-in openings, which can be used to install HVAC ductwork, plumbing lines, and electrical wiring.
Are I-joists better than lumber?
Aside from providing longer spans, I-joist and TRIFORCE® floor systems are superior in strength and precision to solid sawn lumber. They are stiffer, lighter and more easily maneuverable. They also provide a bigger nailing surface to attach the floor membrane than the commonly used 2 x 10.
How much weight can an I-joist hold?
That means the joists can support a minimum of 40 pounds per square foot live load. Though, by consulting the 50 pounds per square foot live load/10 pounds per square foot dead load table, you can see the joists' span would need to be reduced to 11 feet 11 inches to support heavier weight safely.
How much does a wooden I beam cost?
Wood support beams cost $5 to $30 per linear foot on average, with some exotic wood species ranging between $30 and $90 per foot. Wood I-beam prices mainly depend on the type of wood and beam size.
Why do I need a deeper joist?
A deeper joist can be beneficial when the engineered i-joist is needed to span further lengths without intermediate supports such as walls. Quantity: how many pieces are required for floor space or project in general. This will be based on the spacing of the joists (centres).
Is it cheaper to use I joists?
In some instances, it is cheaper to use a deeper joist. Depth: this is simply the depth of joist required.
What is TJI joist?
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.
Can TJI joists be cut?
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
