LVL vs Glulam for Headers: 2026 Complete Comparison (2026)
LVL (Laminated Veneer Lumber) and Glulam (Glue-Laminated Timber) are both engineered wood beams, but they serve different roles in construction. LVL is the workhorse hidden inside walls, while Glulam shines as an exposed architectural element. This comparison covers strength, cost, appearance, and practical applications to help you specify the right beam.

Key Takeaways
- LVL (Laminated Veneer Lumber) and Glulam (Glue-Laminated Timber) are both engineered wood beams, but they serve different roles in construction.
- LVL is the workhorse hidden inside walls, while Glulam shines as an exposed architectural element.
- This comparison covers strength, cost, appearance, and practical applications to help you specify the right beam.
- LVL is the right choice for the vast majority of hidden headers and beams — it is cheaper, more consistent, and fits standard wall framing.
- Glulam is the choice when aesthetics matter, the beam will be exposed, or when curved or very large sections are needed.
| Property | LVL | Glulam |
|---|---|---|
| Construction | Thin veneers glued parallel | Dimensional lumber laminated |
| Typical Use | Hidden headers and beams | Exposed beams, arches |
| Appearance | Industrial — not meant to show | Attractive — designed for exposure |
| Standard Widths | 1.75 in multiples | 3.125, 5.125, 6.75 in |
| Strength Consistency | Very consistent | Good — varies by grade |
| Avg Cost (Per Ft, Similar Capacity) | $4–8/ft | $8–15/ft |
LVL
Pros
- Highly consistent, predictable strength properties. More affordable than Glulam for hidden applications. Available in thin widths that fit standard wall cavities. Easy to source at any lumberyard.
Cons
- Unattractive — not suitable for exposed applications. Limited to straight configurations — no curves or arches. Thinner sections may require doubling or tripling. Must be protected from moisture.
Glulam
Pros
- Beautiful appearance suitable for exposed installations. Available in curved and arched configurations. Wider sections for heavy loads and longer spans. Can be stained or finished to match any decor.
Cons
- More expensive than LVL for equivalent strength. Heavier and bulkier than LVL. Longer lead times for custom sizes. Overkill for hidden header applications.
Best Use Cases
Choose LVL for any hidden beam or header inside walls where cost efficiency and consistent strength matter most. Choose Glulam when the beam will be visible in the finished space, when curved shapes are needed, or when wider sections are required for heavy loads or long spans.
Verdict
LVL is the right choice for the vast majority of hidden headers and beams — it is cheaper, more consistent, and fits standard wall framing. Glulam is the choice when aesthetics matter, the beam will be exposed, or when curved or very large sections are needed. They solve different problems and should not be viewed as direct substitutes.
