Laminated wood is stronger because each thin veneer piece is glued in alternating directions. Thus making it stronger & resistant to warping. Laminate wood is stronger because it consists of layers, each layer is glued together tightly meaning it is very compact and strong.
How far can you span I joists?
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.
How far can a double 2×12 span?

15 feet and 10 inches
A 2×12 with an E of 800,000 psi and Fb of 790 psi also works, since it can span 15 feet and 10 inches. Given a design span of 15 feet 1 inch and a 16 inch joist spacing, first determine which size lumber will work.
How do you calculate beam span?
Calculating the span of a beam requires using various factors that you need to first determine for a structure where the beam is being used.

What are glulam timbers and how they are used?
Glue-laminated timber (glulam) is a structural engineered wood product commonly used for beams and columns in residential and commercial applications. It is a highly visible form of mass timber in contemporary projects, with long spans framing signature designs left exposed to take advantage of wood’s natural aesthetic.
What size lumber for ceiling joists?
The size of the ceiling joist also is accounted for in joist spacing. Although 2-inch by 6-inch lumber is used most often in ceiling construction to support 5-foot by 8-foot sheetrock — the material commonly used for ceilings — other sizes of lumber may be used, such as 2-inch by 4-inch and 2-inch by 8-inch lumber.
