Engineered Wood Products

Modern mass timber buildings are constructed of engineered wood products, often manufactured from multiple layers of sawn lumber, attached to form a solid panel, beam, or column.

Types of CLT

Cross-Laminated Timber
Dowel-Laminated Timber
Glued-Laminated Timber
Laminated Strand Lumber
Laminated Veneer Lumber
Nail-Laminated Timber

Unique CLT Considerations

Construction

CLT panels are constructed of wood, a moisture sensitive material, that is slow to dry if wetted due to its hygric mass.

Wetting

Wetting for prolonged periods can result in dimensional changes, moisture damage, and microbial growth

Drying

As a result, keeping CLT products dry during construction and throughout the building’s service life is critical

Exposure

The speed at which CLT panels may be erected also creates unique field challenges where CLT panels are exposed to the elements for periods of time while awaiting cover.
