many smaller pieces of dimension lumber.
I-Joists correct answers These wood products are used for framing of both roofs and floors and
consist of a top and bottom flange made from solid lumber, LVL, or LSL, and webs made from
plywood or OSB.
Laminated Strand Lumber (LSL) correct answers Made from shredded wood strands, coated
