Home / Products / Cross laminated Timber

Cross-Laminated Timber (CLT) is a cutting-edge engineered wood product that's transforming how we build everything from homes to high-rise buildings. Think of it as super plywood on steroids—but made from solid lumber and designed for serious structural performance.

What Is CLT?
CLT is made by stacking layers of kiln-dried lumber boards perpendicularly (each layer rotated 90° from the previous) and bonding them with structural adhesives. This cross-lamination gives the panel strength in both directions, making it incredibly rigid and stable.
Typically made with 3, 5, or 7 layers.
Manufactured in large panels—up to 60 feet long and 10 feet wide.
Cut to precise dimensions using CNC machines, including openings for doors and windows.

Why CLT Is a Game-Changer?
High Strength-to-Weight Ratio: Strong enough for multi-story buildings, yet lighter than concrete or steel.

Fast Installation: Prefabricated panels reduce on-site labor and waste.
Thermal & Acoustic Performance: Excellent insulation and soundproofing properties.
Fire & Seismic. Resistance: Performs well under fire and earthquake conditions.
Sustainability: Made from renewable wood, with a lower carbon footprint than traditional materials.
Common Uses:
-Walls, floors, and roofs in residential and commercial buildings.
-Long-span structures like auditoriums and sports halls.
-Hybrid systems with glulam beams and CLT panels.
-Modular and prefabricated construction.
CLT is often compared to glulam, but here's the key difference: glulam laminates run in the same direction, while CLT layers are cross-oriented, giving it multi-directional strength. It's not just a material—it's a movement toward greener, faster, and smarter construction.
