Engineered Lumber vs Dimensional Lumber: What to Know

Engineered lumber (LVL, PSL, and I-joists) is stronger, straighter, and spans farther than traditional dimensional lumber, making it ideal for long clear spans, load-bearing beams, and open-concept layouts. Dimensional lumber is still cost-effective for standard walls and framing. RS Development Group specifies the right material for each part of your project — call (774) 512-3176.

What is engineered lumber?

Engineered lumber is manufactured from wood veneers or strands bonded under pressure — LVL (laminated veneer lumber), PSL (parallel strand lumber), and engineered I-joists. Because it’s made to precise specifications, it’s stronger and far more dimensionally stable than sawn lumber, with fewer knots, warps, and callbacks.

When should you use it?

• Long, clear spans without support posts (great rooms, open kitchens).
• Load-bearing beams when removing a wall for an open-concept remodel.
• Floor systems where you want stiff, quiet, bounce-free floors.
• Anywhere strength and straightness justify the higher material cost.

Is it worth the extra cost?

For the right applications, absolutely — it enables designs dimensional lumber can’t achieve and reduces callbacks from warping and settling. As framing specialists, we use each material where it makes sense, so you get performance where it counts and value where you don’t need the upgrade.
