Choosing Framing Lumber

What are the different grades of 2x4 lumber?

Lumber that's 2 to 4 inches thick, 6 inches and wider. Graded as Select Structural, 1, 2, or 3.

What is better #1 or #2 lumber?

Typically wood that is two or more inches thick is graded only for strength, denoted by #1, #2 and so on. And because stronger lumber has fewer and smaller knots, it's typically more attractive.

What's the strongest 2x4 wood?

Doug-Fir. Douglas-fir, popularly known as Doug-fir, is undoubtedly the best and most common structural lumber. It is most architects' and engineers' go-to lumber species and this is not just because of its remarkable dimensional stability. It is also among the strongest and most durable softwood lumbers.

Are studs hardwood or softwood?

Hardwoods are oftentimes denser than softwoods. For this reason, they'll be used for flooring, construction, decks, and high-quality furniture. Softwoods aren't always dense, but they do have a wide range of applications. For instance, softwood is used for framing lumber, such as studs, joists, and beams.

Why is pressure treated wood cheaper than framing lumber?

An obvious advantage of untreated lumber is its price; it's much cheaper than treated lumber. Since CCA-treated lumber was taken off the market, new treatment techniques use high levels of copper, which is more expensive. As a result, the cost of treated wood has risen considerably [source: Morrison].

Are 2x4 pressure treated?

All lumber, from the common 2x4 to specialty marine plywood, is either pressure treated or not. Pressure treated wood does last longer without rotting and resists insect damage, but it's not right for every purpose either.

Should I put insulation in stud wall?

FAQs. Should stud walls be insulated? Yes, insulating a stud wall helps reduce sound transfer and improve the fire safety properties of the room and building. It will improve thermal performance where required too.

How thick should a stud wall be?
