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.

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 stronger than timber?
Are I joists stronger than timber? I joists are specifically designed to offer strength in areas that dimensional lumber is incapable of. They can span greater distances, and are considered to be 50% stiffer than dimensional timber under traditional frame spacing.
