Wood Products
Wood products are formed by bonding wood strands, veneers, lumber, and waste materials like wood shreds for structural and nonstructural applications.
Glue-laminated wood is obtained by combining numerous smaller pieces of dimensional lumber with glue.
Cross-laminated timbers are structural panels made from solid lumber, where the grain direction of the wood pieces alternates between each layer.
Nail-laminated timber is made from dimensional lumber pieces laid side by side and fastened with nails or screws.
In contrast, dowel-laminated timber follows a similar procedure but uses seasoned wooden dowels instead of metal fasteners.
Laminated strand lumber is produced using longer adhesive-coated, shredded wood strands that are given a rectangular shape and heat-cured under pressure.
Oriented strand lumber, on the other hand, is made from shorter strands following a similar process.
This process also produces parallel-strand lumber when applied to thin veneer strips arranged in a uniform parallel fashion.
Laminated veneer lumber is obtained by bonding thin sheets of wood veneer, each as wide as the final product's depth, together to form thicker, more robust structural members.
Wood products encompass a broad range of materials crafted from wood strands, veneers, lumber, and even waste wood-like shreds, designed for both structural and nonstructural purposes. Various specialized wood products have been developed to enhance strength, durability, and versatility in building applications.
Glue-laminated wood, often referred to as glulam, combines multiple smaller pieces of dimensional lumber using adhesives to form a single, larger piece. Cross-laminated timber consists of structural panels made from solid lumber with layers arranged so that the grain direction alternates, enhancing the panel's strength and stability.
Nail-laminated timber is created by placing dimensional lumber side by side and fastening the pieces together with nails or screws. Dowel-laminated timber uses a similar construction but replaces metal fasteners with seasoned wooden dowels, which avoids the thermal bridging associated with metal.
Laminated strand lumber and oriented strand lumber are both made by bonding longer or shorter wood strands, respectively, coated in adhesive and then heat-cured under pressure to form strong, uniform panels. Parallel-strand lumber involves thin veneer strips arranged in parallel before being bonded and cured.
Laminated veneer lumber is manufactured by gluing together multiple layers of wood veneer in the same direction to create a thick, strong member used in various structural applications.
These innovative wood products provide enhanced performance and sustainability in modern construction projects.
