Engineered wood
Engineered wood products replace steel and concrete in construction.
Engineered wood, also called mass timber, composite wood, man-made wood, or manufactured board, is a range of derivative wood products manufactured by binding or fixing strands, particles, fibers, veneers, or boards of wood together with adhesives or other methods of fixation to form composite material. These products are engineered to precise design specifications, tested to meet national or international standards, and provide uniformity and predictability in structural performance. They are used in applications from home construction to commercial buildings to industrial products, and can replace steel and concrete assemblies in many building projects.

Lore & Background
Engineered wood products are made from the same hardwoods and softwoods used to manufacture lumber. Sawmill scraps and wood waste can be used for products composed of wood particles or fibers, while whole logs are typically used for veneers such as plywood, medium-density fibreboard (MDF), or particle board. Some products, like oriented strand board (OSB), can use trees from the poplar family, a common but non-structural species. Similar engineered products can be made from bamboo or other lignin-containing materials such as rye straw, wheat straw, rice straw, hemp stalks, kenaf stalks, or sugar cane residue, containing no actual wood but vegetable fibers.
Reader's Guide
Engineered wood has become significant in modern construction due to its ability to provide uniform, predictable structural performance while using resources efficiently. The panels vary in size, ranging upwards of 64 by 8 feet, and cross-laminated timber can be of any thickness from a few inches to 16 inches or more. These products are machine graded to be evaluated and categorized for mechanical strength and suitability for specific applications.
Did You Know?
- Engineered wood panels can range upwards of 64 by 8 feet (19.5 by 2.4 m).
- Flat-pack furniture is typically made out of man-made wood due to its low manufacturing costs and low weight.
- Some engineered wood products, like OSB, can use trees from the poplar family, a common but non-structural species.
Frequently Asked Questions
What is Engineered wood?
Engineered wood is a broad family of composite wood products created by bonding wood strands, particles, fibers, veneers, or boards together with adhesives or mechanical fixation. It is also commonly referred to as mass timber, manufactured board, or man-made wood.
What are the main types of Engineered wood?
The category spans plywood, oriented strand board (OSB), fiberboard, particle board, structural composite lumber (including LVL, PSL, and LSL), I-joists, and mass timber panels. Each type is tailored to a specific structural or finishing role.
Why do builders choose Engineered wood over steel or concrete?
Engineered wood products are designed to meet precise structural specifications and are tested against national or international standards, giving them uniform and predictable load-bearing performance. They offer a lighter, often more sustainable alternative that can replace steel and concrete across residential, commercial, and industrial projects.
How is Engineered wood different from a solid timber beam?
Rather than relying on the natural variability of a single log, engineered wood is fabricated to exact design tolerances so every panel or member performs consistently. This engineered uniformity makes it easier to spec, inspect, and trust in critical structural applications.
Where exactly is Engineered wood used in the real world?
You will find it in everything from residential framing (I-joists, OSB sheathing) to multi-story commercial buildings (cross-laminated mass timber) and industrial components. Its versatility lets a single material family serve both structural and finish-grade roles across the construction spectrum.
