Framing Lumber and Engineered Wood Guide

Dimensional lumber, LVL beams, I-joists and trusses explained, with where each one is used in a house.

A house frame uses several kinds of wood. Dimensional lumber such as two by four studs and two by ten joists is the basic building block. Laminated veneer lumber, or LVL, makes strong beams. I-joists make long, flat floors, and trusses make efficient roofs.

Each material has strengths. Engineered products are straighter and stronger for their size, while dimensional lumber is flexible and easy to work. Engineers and plans specify sizes, and we install them exactly as drawn.

Questions

Framing Lumber FAQ

Can I substitute a smaller beam?

No. Beam sizes come from engineering, and changes must be approved.

Why are engineered beams used?

They carry more load in less depth and stay straight.

Does lumber need to be treated?

Wood in contact with ground or concrete needs treatment or protection.
