Rosboro Glulam and X-Beam: What Builders Should Know
Rosboro glulam is glued laminated timber made in Oregon for beams, headers, and columns. Rosboro X-Beam is glulam manufactured in standard framing widths, so it fits flush with 2×4 and 2×6 walls without furring or built-up members. Impacco supplies Rosboro glulam and X-Beam and ships long members to Alaska and Hawaii.
What Is Glulam?
Glulam is made by bonding layers of dimensional lumber with structural adhesives. The result is a large, strong member that can span long distances and be left exposed for an architectural look.
Why X-Beam
- Framing widths that match standard walls
- One piece instead of built-up headers
- Clean appearance when left exposed
- Stock sizes that simplify ordering
Glulam vs. LVL
| Feature | Glulam (X-Beam) | LVL |
|---|---|---|
| Made from | Layers of lumber | Thin wood veneers |
| Appearance | Attractive when exposed | Usually hidden |
| Widths | Framing widths in one piece | Often plied together for width |
| Typical use | Headers, beams, exposed members | Headers, beams, rim boards |
Shipping Long Beams
Glulam beams can be long and heavy. We plan container or platform loading around beam lengths, support members fully, and wrap them to keep them dry. Learn more about container vs. platform loading.
