Hereof, Are engineered floor joists stronger?

Engineered floor joists are joists that use engineered wood in conjunction with standard lumber to comprise a more lightweight yet stronger joist than just using traditional lumber. ... They can span longer distances than other joists but cannot be cut or trimmed once fabricated.

Moreover, What is the best type of floor joist?. Lumber Grade

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.

Besides, What are the advantages of using engineered lumber over solid lumber?

Using engineered lumber can shave time and labor costs off the installation process, as these products are typically lighter than natural lumber. Not only that, but due to their greater strength and stability, they can be spaced farther apart during installation, reducing overall installed cost per square foot.

What is one disadvantage of using engineered I-joists instead of dimensional lumber for a floor?

Engineered lumber often does not perform as well when exposed to fire or water. The thinner material that comprises the web of the I-joist can be relatively easily damaged or burned through by fire. The OSB web of the I-joists can be swelled by absorption of excessive moisture causing weakening of the web.
