Finishing Glued Laminated Timbers

Structural glued laminated timbers (glulam) are manufactured from individual wood members (laminations or lams) that are bonded together with wet-use adhesives to form a finished member. These individual lams are typically solid-sawn lumber but the outermost laminations of bending members may sometimes be composed of laminated veneer lumber (LVL).

This publication is designed for: glulam manufacturers, builders, contractors

This publication discusses various considerations for glulam manufactured entirely from solid-sawn lumber.

Key sections include:

• Appearance classifications

  • Relation to structural performance

  • Applications of different appearance classifications

• Finishing considerations

  • Types of finish

  • Finishing glulam that may be subject to moisture
