Deck 19: Products Manufactured From Wood

Question 1

Explain in general what plywood panel construction is and how it is constructed.

Answer 1

Plywood, manufactured for nearly a century, is one of the most widely used wood products. The manufacturing process uses a lathe to peel thin veneer from water saturated logs. Plywood panels are made by bonding together the thin layers, or plies, of wood. The grain in each ply layer is arranged perpendicular to the grain of the next layer. Panels always have an odd number of plys, such as three, five, or seven. Each ply may be a single thickness veneer or two veneers glued together.

Question 2

Define Class 3 hardboard.

Answer 2

Class 3 is service-tempered. Service-tempered class is impregnated with siccative material and stabilized by heat and additives. Its properties are substantially better than Service Grade.

Question 3

Define Class 1 hardboard.

Answer 3

Class 1 is tempered hardboard. It is impregnated with siccative material and stabilized by heat and special additives to impart substantially improved properties of stiffness, strength, hardness, and resistance to water and abrasion, as compared with the Standard Class.

Question 4

____ panels are used where panels may be subjected to occasional moisture after they are in service.

A) Exposure 1
B) Exposure 2
C) Exterior
D) Interior

Question 5

What are glulams? Briefly describe their characteristics.

Question 6

____ is a structural engineered wood that utilizes wood from species of wood that are not large or strong enough to be useful in solid lumber products, uses 12 in. long strands that are cut from logs, dried, and immersed in resin before being pressed into solid billets, and strands are aligned parallel to each other to take advantage of the natural strength of the wood.

A) Plywood-lumber beams
B) Laminated stand lumber
C) Laminated veneer lumber
D) Parallel strand lumber

Question 7

C) Softboard
D) Waferboard

Question 8

____ is an engineered wood product produced by bonding thin wood sheets together into a large billet, where the grain runs parallel to the long direction.
