Difficulty: EasyLumber and Engineered Wood

Match each engineered wood product on the left with its defining manufacturing and structural characteristic on the right.

  • PlywoodThin sheets of wood veneer bonded together with grain directions alternating at right angles
  • Oriented Strand Board (OSB)Layered rectangular wood flakes cross-oriented and pressed with waterproof adhesive
  • Medium-Density Fiberboard (MDF)Fine wood fibers mixed with resin and wax, pressed into dense panels with no visible grain
  • Glued Laminated Timber (Glulam)Multiple solid lumber laminations bonded together to create heavy load-bearing structural beams

Answer

Plywood matches with cross-laminated wood veneers; Oriented Strand Board (OSB) matches with cross-oriented rectangular wood flakes; Medium-Density Fiberboard (MDF) matches with fine wood fibers pressed into grain-free dense panels; Glued Laminated Timber (Glulam) matches with multiple solid lumber laminations bonded into structural beams.
Each engineered wood product is correctly paired based on its primary components: Plywood consists of alternating veneer plies; OSB consists of compressed, cross-oriented strands; MDF is made from refined wood fibers pressed into smooth boards; Glulam is built from multiple solid dimensional lumber boards glued into heavy beams.

Step-by-Step Solution

1
Identify the base material and grain structure of Plywood.
Plywood uses peeled rotary veneers glued in alternating perpendicular directions.
Alternating the veneer grain grain reduces wood movement and distributes strength across both width and length.
2
Identify the composition of Oriented Strand Board (OSB).
OSB is composed of distinct cross-oriented wood strands bonded with waterproof resin.
The layered strand orientation gives OSB engineered structural properties comparable to plywood for subflooring and roof decking.
3
Identify the manufacturing characteristics of Medium-Density Fiberboard (MDF).
MDF is made from fine pulverized wood fibers combined with binders and pressed into smooth, uniform panels.
The lack of knots or grain makes MDF ideal for machining and painting in cabinetry and trim work.
4
Identify the structural role and makeup of Glulam.
Glulam utilizes full-dimension solid lumber pieces laminated together.
Bonding dimension lumber allows the production of long, heavy-duty structural beams and columns capable of spanning wide openings.
