Unit 7 — Engineered Wood Products Performance rated panels include plywood, oriented strand board, and composite panels.

Unit 7 — Engineered Wood Products Strength and stiffness properties are affected by wood

Unit 7 — Engineered Wood Products Strength and stiffness properties are affected by wood species.

Unit 7 — Engineered Wood Products Cross-lamination provides dimensional stability to plywood panels.

Unit 7 — Engineered Wood Products Cross-lamination provides dimensional stability to plywood panels.

Unit 7 — Engineered Wood Products The manufacture of plywood begins with peeling veneer

Unit 7 — Engineered Wood Products The manufacture of plywood begins with peeling veneer strips from peeler logs. The veneer strips are then cross-laminated to produce plywood panels.

Unit 7 — Engineered Wood Products Veneers of higher grade are used on the faces and backs of panels that will be exposed.

Unit 7 — Engineered Wood Products Medium density overlay plywood is used for siding

Unit 7 — Engineered Wood Products Medium density overlay plywood is used for siding and other exterior applications, and provides a smooth, toothed surface for a paint base.

Unit 7 — Engineered Wood Products Plyform is a performance rated plywood panel that

Unit 7 — Engineered Wood Products Plyform is a performance rated plywood panel that provides a smooth and durable concreteforming surface.

Unit 7 — Engineered Wood Products Fiberglass-reinforcedplastic plywood panels consist of fiber-reinforced overlays bonded

Unit 7 — Engineered Wood Products Fiberglass-reinforcedplastic plywood panels consist of fiber-reinforced overlays bonded to a plywood panel.

Unit 7 — Engineered Wood Products Oriented strand board is a structural wood panel

Unit 7 — Engineered Wood Products Oriented strand board is a structural wood panel commonly used for wall sheathing.

Unit 7 — Engineered Wood Products The manufacture of oriented strand board (OSB) begins

Unit 7 — Engineered Wood Products The manufacture of oriented strand board (OSB) begins with soaking and debarking logs before they are shredded. Wood strands up to 6″ long are formed into layers and crosslaminated to provide OSB with its strength and dimensional stability.

Unit 7 — Engineered Wood Products Composite panels have veneer faces with wood fiber

Unit 7 — Engineered Wood Products Composite panels have veneer faces with wood fiber crossbands and core.

Unit 7 — Engineered Wood Products Performance rated panels are identified by trademarks. Additional trademarks and descriptions are shown in the Appendix.

Unit 7 — Engineered Wood Products Hardwood plywood is commonly used for interior finish

Unit 7 — Engineered Wood Products Hardwood plywood is commonly used for interior finish applications.

Unit 7 — Engineered Wood Products Hardwood plywood panel grades are based on natural

Unit 7 — Engineered Wood Products Hardwood plywood panel grades are based on natural growth characteristics, including color variations, burls, and pin knots, and the number of repairs in the panel face and back.

Unit 7 — Engineered Wood Products Medium density fiberboard is used for a variety

Unit 7 — Engineered Wood Products Medium density fiberboard is used for a variety of exterior and interior applications including siding. Note the spacer block being used to uniformly space the courses of siding.

Unit 7 — Engineered Wood Products Hardboard is a nonstructural panel product that has

Unit 7 — Engineered Wood Products Hardboard is a nonstructural panel product that has no grain pattern and has a uniform density, thickness, and appearance.

Unit 7 — Engineered Wood Products Particleboard is a nonstructural reconstituted panel consisting of

Unit 7 — Engineered Wood Products Particleboard is a nonstructural reconstituted panel consisting of particles that are bonded together using a synthetic resin or binder. A plastic laminate is applied to the particleboard for certain applications.

Unit 7 — Engineered Wood Products Glulam timbers are commonly used for beams in commercial and residential construction.

Unit 7 — Engineered Wood Products Glulam timbers can be formed to produce curves

Unit 7 — Engineered Wood Products Glulam timbers can be formed to produce curves or arches.

Unit 7 — Engineered Wood Products Laminated veneer lumber (LVL) is composed of layered

Unit 7 — Engineered Wood Products Laminated veneer lumber (LVL) is composed of layered veneers and waterproof adhesive and is commonly used for beams. Note the wood I-joists attached to the LVL beam.

Unit 7 — Engineered Wood Products Parallel strand lumber (PSL) is used for beams,

Unit 7 — Engineered Wood Products Parallel strand lumber (PSL) is used for beams, headers, and loadbearing columns. PSL is used for the main beam and supporting column in this application.

Unit 7 — Engineered Wood Products Wood I-joists are composed of oriented strand board

Unit 7 — Engineered Wood Products Wood I-joists are composed of oriented strand board or plywood webs with dimension lumber or laminated veneer lumber flanges.

Unit 7 — Engineered Wood Products Rim boards tie together wood I-joists and fill

Unit 7 — Engineered Wood Products Rim boards tie together wood I-joists and fill the space between the top plate and bottom plate of two wall sections.

Unit 7 — Engineered Wood Products The ends of short pieces of lumber are

Unit 7 — Engineered Wood Products The ends of short pieces of lumber are milled to produce fingers. The short pieces are then attached to each other to form finger-jointed lumber, which is used for structural applications such as studs, plates, joists, and rafters.

Unit 7 — Engineered Wood Products Finger-jointed lumber is divided into two end-use applications.

Unit 7 — Engineered Wood Products Finger-jointed lumber is divided into two end-use applications. Fingerjointed lumber acceptable for all structural applications is stamped with “CERT. EXT. JNTS. ” while finger-jointed lumber acceptable only for vertical applications is stamped with “VERTICAL USE ONLY” or “STUD USE ONLY. ”
