How do you frame a TJI floor?
What is the strongest floor joist? Since knots and other defects weaken wood, higher grades of lumber (designated as clear, select, or #1) are considered stronger than lower grades.

What are TJI joists made of?
TJI vs LVL
TJI joists have a top and bottom flange made of solid or finger-jointed wood with a perpendicular sheet of OSB or plywood (LVL) in between. LVL (laminated veneer lumber) looks more like a plank except it’s made up of layers of thin veneer glued, heated, and pressed together, like plywood but much thicker.
Is LVL stronger than wood? In addition to being flat and straight, engineered studs are strong. Laminated veneer lumber (LVL) studs can be two times stronger in compression and tension than standard framing lumber of the same dimension.
How much does a 20ft LVL cost?
The LVL beam thickness is usually between 1.75 and 7 inches. The price for beams that fit 10 feet of space will range from $3 to $5 per linear foot, while a 20-feet span will need a beam that costs $6 to $11 per linear foot.
What is a Microlam?

Can you drill holes in I-joists? You can drill the holes anywhere along the length of the joist (first photo). If you have manufactured I-joists, you can drill holes up to 1-1/2 in. diameter almost anywhere in the web area (the area between the flanges).

What is the bottom of an I-joist called? An I-joist has two main parts, the web and flange. The web is sandwiched between a top and bottom flange, creating the “I” shape.

What are the disadvantages of LVL?
Although its dimensional stability is better than solid wood, the product may result in some defect, such as warping, if it is not properly stored in the warehouse. Also, LVL requires high capital investment to have relatively low production cost.
Is GLULAM the same as LVL? A glulam beam looks like a stack of 2 x 4s (or larger lumber) glued together on their broadsides. This is in contrast to other engineered members, such as LVL (laminated veneer lumber) and Microlam beams, which look like very thick plywood, with very thin layers of wood glued together to form a thicker mass.
Will LVL beams sag? It is not unsafe because the LVLs will have to be seriously sagging before anything would happen. 5/8″ is just enough to disturb the finish and annoy you. You can either install a beam in the middle of the room or put in a better header.
