Cross-Laminated Timber (CLT) is a mass timber product made by gluing together layers of kiln-dried solid wood, usually spruce, pine, or fir—with each layer laid perpendicular to the one below. This cross-lamination enhances strength, stability, and load distribution in both directions.

How CLT Is Made

• Lumber Selection: Kiln-dried, defect-free softwood (e.g., spruce, fir).
• Layering: 3, 5, 7, or more layers stacked at 90° angles.
• Adhesive Bonding: Structural glue secures layers under high pressure.
• Panel Sizes: Custom sizes prefabricated for walls, floors, or roofs.

Common Applications

1. Floors, walls, and roofs
2. Load-bearing and shear walls
3. Prefabricated modules and mass timber buildings
4. Mid-rise and high-rise wood construction

Benefits of CLT

• Structural Strength: High load-bearing capacity and stiffness
• Dimensional Stability: Resists warping, shrinking, and swelling
• Fast Construction: Prefab panels reduce on-site build time
• Sustainability: Made from renewable wood, stores carbon
• Fire Resistance: Chars predictably, maintaining structural integrity
• Acoustic & Seismic Performance: Performs well in noise isolation and earthquakes
• Aesthetic Appeal: Can be left exposed for a clean, natural look
