`
`Wood is good. It is the earth's natural, energy ellicient and renewable
`building material.
`
`Engineered wood is a better use of wood. It uses less wood to make
`more wood products.
`
`That's why using APA trademarked plywood, oriented strand board and APA 1-1WS
`glued laminated timbers is the right thing to do.
`
`A few facts about \A'oo(I.
`We're not running out of trees. One-third of the United States land base --
`731 million acres - is covered by forests. About two-thirds of that 731 million sores is
`suitable for repeated planting and harvesting of timber But only about half of the land
`suitable for growing timber is open to logging. Most of that harvestable acreage also is
`open to other uses, such as camping, hiking, hunting, etc.
`
`We're growing more wood every day. American landowners plant more than
`t wo billion trees every year. In addition, millions of trees seed naturally. The forest
`products industry, which comprises about 15 percent of forestland ownership, is
`responsible for 41 percent of replanted forest acreage. That works out to more than one
`billion trees a year, or about three million trees planted every clay. This high rate of
`replanting accounts for the fact that each year, 27 percent more timber is grown
`than is harvested.
`
`Manufacturing wood products is
`energy efficient. Wood products made
`up 47 percent of all industrial raw
`materials manufactured in the United
`States, yet consumed only 4 percent of
`the energy needed to manufacture all
`industrial raw materials, according
`to a 1987 study.

`produces 1.07 tons of oxygen and absorbs 1.47 tons of carbon dioxide.

`
`Edge Sealing
`Application of a coating (e.g., sealant,
`paint) to tile edges of a wood structural
`panel to reduce its water absorption.
`Edge seal before painting the panel
`surface if panel edges will he exposed
`to repeated wetting and drying.
`
`Edge Spacing
`See PANEL SPACING.
`
`Edge Support
`Support, such as panel clips or Illinher
`blocking, installed between framing
`members at wood structural panel edges
`to traiister loads fiom one panel to the
`other across the joint. Panels with
`tongue arid-groove edges can be used in
`litany applications without additional
`edge support.
`
`Edge Treatntei
`Edge finishing method, such as handing
`with wood or plastic, or filling with
`put ty or spackle.
`
`EDGE TREATMENTS
`
`B utt edging. Keep edges square;
`use matching strip of solid wood.
`
`Butt edging. Keep edges square;
`use matching strip of solid wood.
`
`"Mitered" butt edging. Use glue
`and brads to fasten strips.
`
`Edge. Void
`A panel defect in which the edge or end
`of an inner ply has split or broken away
`d uring manufacture, leaving a gap in the
`edge of the plywood panel.
`
`Einhossed
`A panel surface treatment. Heal and
`pressure against a master pattern
`i mpress a variety of textured effects
`i nto panel surfaces, which remain
`smooth and pailitahle.
`
`End Grain
`The end of a piece of wood exposed
`\viten the wood fibers are cut across
`the grain. All wood structural panel
`edges are eruct grain, and should be
`finished accordingly.
`
`End Spacing
`See PANEL SPACING.
`
`Engineered 21" Framing
`A building system using wood structural
`panels over lumber flaming spaced
`24 inches on center in walls, floors
`awl roof. The system's series of in-line
`flames trusses, studs and joists —
`provide cost effective materials utiliza
`t ioil and simpler, faster construction.
`ft is recognized by major model
`codes and the HI IA.
`
`Expansion
`Moisture absorption causes wood to
`expand. Spacing between panel edges
`and ends is recomtneficled to allow for
`any possible panel swelling. See
`PANEL SPACING.
`
`Exposure Durability Classification
`Exposure ratings for APA wood
`structural parcels designated in APA
`trademarks as Exterior, Exposure 1 ,
`Exposure 2, or Interior.
`
`Exterior panels have a fully waterproof
`bond and are designed for applications
`subject to permanent exposure to the
`weather or to moisture.
`
`Exposure 1 panels have a fully water
`proof bond and are designed for appli-
`cations where long construction delays
`may be expected prior to providing
`protection, or where high moisture
`conditions may he encountered in
`service. Exposure 1. panels are made
`with the saute exterior adhesives used in
`Exterior panels. However, because other
`compositional factors may affect howl
`performance, only Exterior panels
`should be used for permanent
`exposure to the weather.

`Face
`The highest-grade side of any veneer-
`faced panel that has outer plies of differ-
`ent veneer grades. Also, either side of a
`pmei w1,,, grading jades draw no
`distinction between facips. For example,
`the face of an A-C panel is the side with
`the A-grade outer ply. Both sides of an
`A A or B-B panel are referred 10 as faces.
`
`Face CIll'CRing
`Partial separation Of wood fibers parallel
`I() grain in the wood or veneer surfaces
`of panels caused chiefly by the strains
`of weathering and seasoning.
`See CHECKING.
`
`Face
`Direction of the grain of the outer ply
`(face) of e veneer-faced panel in relation
`to its supports. A panel's greatest stiff
`ness and strength is parallel to the face
`grain. Therefore, in construction, run
`the face grain or long dimension of the
`panel across supports for greatest stiff-
`ness and strength.
`
`Fascia
`Wood or plywood trim used along the
`cave ou the gable (lid of a structure.
`
`Fiberglass Reinforced Plastic (EPP)
`A tough, nmscuff plywood coating
`made of glass fibers combined with
`resins. These coated panels (composite)
`are used in truck and trailer bodies,
`containers and concrete forms. Seamless
`panels /0 feet long and longer can be
`produced as trailer sidewalls or roofs.
`
`Filler
`A material for filling nail holes, checks,
`chicks or other blemishes in surfaces
`of wood before application of paint,
`varnish or other finishes.
`
`Exposure 2 panels (identified as
`Interior with intermediate glue under
`PS 1) are intended for protected con-
`struction applications wlicre only mod-
`erate delays in providing protection
`from moisture may be expected.
`
`Interior panels or panels which lack
`further glueline information in their
`trademarks are manufactured \vith inte-
`rior glue and are intended for interior
`applications only.

`Finishes
`Stains, paints or sealers wflich protect,
`color or enhance the natural beauty of
`Wood structural panels.
`
`Exterior finishes primarily protect
`siding and maintain its appearance.
`They minimize the vveitlierilig aclion
`w hich roughens and erodes the surface
`of unfinished wood. Different finishes
`give varying degrees of protection so the
`type, quality, quantity and application
`m ust be considered to achieve the
`desired performance. All exterior panel
`edges should be sealed if the panels will
`be painted or stained. Sealing while
`panels are stacked is easiest. Exterior
`finishes recommended for wood strum
`tonal panels include semi- ransparent
`stain, solid-color stain and acrylic:
`latex paint.
`
`Interior finishes: Preparation is
`minimal. Overlaid (MD0 and I WO)
`plywood needs no preparation; sanded
`and textured grades require only touch-
`sanding. Recommended interior finishes
`include oil On paint, latex paint,
`stain and sealer.

`Fin, killed Systems

`are performed by agencies such as
`Underwriters Laboratories, Inc. A
