BOISE GLULAM ® Beam Product Guide WEBGLPROD 05/2013 . . . Just ask for BOISE GLULAM® beams 2 Glued laminated timbers from Boise Cascade Engineered Wood Products add functional beauty to any residential or commercial project. Just ask for BOISE GLULAM® beams. No discussion of engineered wood products is complete without mention of glued laminated timber. Glulams are sometimes forgotten in what has become an increasingly crowded field of newer products. Laminated timbers are often the most cost-effective and easy-toinstall alternative for beam applications to residential, commercial and light industrial construction. It is usually easy to determine whether to specify a balanced or unbalanced layup and whether to choose Industrial or Architectural appearance grade beams. The benefit to BOISE GLULAM ® beams is that they can be manu factured either with or without camber. Most stock beams are available with either a small amount of camber (5000' radius) or no camber, depending on market demands. BOISE GLULAM® beams are manufactured primarily from Douglas FirLarch and other softwood species and carry the APA trademark. Rough Sawn Glulam Just one of our custom beams CUSTOM BEAMS Custom beams are used when large cross-sections, longer lengths, curved and arched shapes, different appearances, or specific certifications are required. Custom widths: 3⅛", 3½", 5⅛", 5½", 6¾", 8¾", 10¾", 12¼", 14¼" Depths ranging from 6" to 57½" (depending upon the width) STOCK BEAMS For most residential applications, stock beams are the product of choice. BOISE GLULAM® stock beams are available through our trusted distributors, located strategically throughout the country. Our beams are manufactured in widths of 3⅛", 3½", 5⅛", 5½", 6¾", and 8¾", with depths ranging from 6" to 24" and lengths up to 66 feet, with or without camber. Stock beams are available in Architectural appearance grade except 3½" and 5½" which are Framing header grade only. Architectural Appearance is intended for exposed applications but can also be used for concealed beams, headers, columns, and rafters. Check with your local distributor for availability. BOISE GLULAM® custom beams are manufactured on a made-toorder basis. Please call to determine availability of BOISE GLULAM® custom beams.

Back Cover Boise Cascade EWP • BOISE GLULAM® Product Guide • 005/23/2013 BOISE GLULAM® Stock Beams BOISE GLULAM® Stock Beam and Column Sizes 5⅛" 5½" 8¾" 6¾" 3⅛" 3½" 6" to 24" 6" to 24" 7½" to 24" 9" to 24" Architectural and Industrial Appearance Beams Architectural and Industrial Appearance Beams 6" to 24" Header (Framing) Beams These beams are the beams of choice in applications where members are exposed to view, because they have a smooth, attractive finish. Stock beams are often supplied with this appearance so they may be exposed to view in the finished structure. Voids greater than ¾" are filled, three sides (excluding the top) are planed or sanded, and edges are eased on the bottom face of the member. INDUSTRIAL APPEARANCE BEAMS These beams are used in concealed applications or in other places where appearance is not of primary importance, such as such as commercial buildings, warehouses, and garages. Voids are not filled, and only the two wide surfaces are planed. HEADER BEAMS – FRAMING GRADE BOISE GLULAM® headers are commonly used for concealed applications such as doors and windows where appearance is not of importance. They come in two common widths, 3½" and 5½". Check with your local distributor for availability. COLUMNS Glulam columns are straight and dimensionally true, making framing an easy task. Because columns are available in long lengths, the members do not have to be spliced together, as is often necessary with sawn lumber. The columns can be exposed to view as a unique architectural feature of the framing system. BOISE GLULAM® columns have all four edges eased to match the widths of the Architectural glulams beams and have the same architectural appearance. All sides may be exposed to view. BALANCED AND UNBALANCED BEAM LAYUPS 6" to 24" Header (Framing) Beams ARCHITECTURAL APPEARANCE BEAMS The most critical areas of a glulam beam are the outside laminations. Thus, the strongest laminations are placed in these areas in either unbalanced or balanced layups. In unbalanced beams, typically known as V4s, the bottom lamination is stronger than all the other laminations. This allows for a more efficient use of timber resources. It is very important to install unbalanced BOISE GLULAM® beams with the top side up. (The word "top" is always printed on the corresponding side.) V4 glulams may be designed and installed in both single and multiple-span applications, and in relatively short cantilevers. Balanced glulam beams, or V8s, have the same high-strength laminations on both the top and bottom of the beam, creating a symmetric layup. A V8 glulam can be designed for multiple-span conditions and cantilevers. V8s can also be used for single spans, but V4s are most cost-effective for this type of application. V8 BOISE GLULAM® beams may be special ordered at an additional cost; check with your local distributor for availability. Boise Cascade EWP • BOISE GLULAM® Product Guide • 05/23/2013 3 3⅛" to 8¾" 6" to 9" Columns Columns APPARENT & TRUE MODULUS OF ELASTICITY A beam’s deflection is dependent upon the modulus of elasticity (MOE) and the beam’s cross-section. There are two components of deflection, deformation from bending and deformation from shear. An “apparent” MOE is typically published for wood structural products. The apparent MOE encompasses both deflection components. However a “true” MOE value is sometimes referenced, which only corresponds to the bending portion of deflection and thus is “shear-free”. A true MOE is approximately 5% higher than the apparent MOE (the difference does vary slightly depending upon span length and beam depth). For example, the true MOE of a 24F-V4/DF glulam is approximately 1,900,000 psi but the apparent and published MOE is 1,800,000 psi. The designer must add the shear deflection component to bending deflection when using the higher true MOE. LAYUP COMBINATIONS Balanced Vs Unbalanced Layup Example No. 2D No. 2 No. 2 T.L.

Beams may be manufactured with a 5000' radius camber on a special order basis. The industry has moved to a 5000-foot radius camber which has become the standard camber. Camber is specified mostly to reduce the aesthetic effect of long-span members. Camber can also be specified to reduce the amount of deflection or create roof drainage — for example, it may be used to limit water collection on near-flat roofs. For relatively long span lengths, deflection may control the design of glulam beams. Building codes limit deflection for floor and roof members with "L/over" limits. The "L" is simply the span length in inches. It can be divided by a number — for example, 360 for live load on floors — to determine the maximum amount of deflection a member can have for the corresponding span under full design loads. Thus, a greater amount of deflection is allowed for members with longer spans. The table to the below illustrates the camber at the center of the beam when specific lengths and radii are specified. Camber is the amount of curvature (reverse deflection) that is built into a glulam beam during the manufacturing process to offset a portion of the CAMBER CURVATURE IN INCHES Radius In Feet Beam Length 400 600 800 1000 1200 1400 1600 1800 2000 2200 2400 2600 2800 3000 3200 3500 5000 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 40 42 44 46 48 50 52 54 56 58 60 62 64 66 68 70 72 74 76 0 0 ⅛ ¼ ⅜ ½ ¾ 1 1¼ 1½ 1⅞ 2⅛ 2½ 3 3⅜ 3⅞ 4⅜ 4⅞ 5⅜ 6 6⅝ 7¼ 7⅞ 8⅝ 9⅜ 10⅛ 10⅞ 11¾ 12⅝ 13½ 14⅜ 15⅜ 16⅜ 17⅜ 18⅜ 19½ 20½ 21⅝ 0 0 ⅛ ⅛ ¼ ⅜ ½ ⅝ ¾ 1 1¼ 1½ 1¾ 2 2¼ 2½ 2⅞ 3¼ 3⅝ 4 4⅜ 4⅞ 5¼ 5¾ 6¼ 6¾ 7¼ 7⅞ 8⅜ 9 9⅝ 10¼ 10⅞ 11½ 12¼ 13 13¾ 14½ 0 0 ⅛ ⅛ ¼ ¼ ⅜ ½ ⅝ ¾ ⅞ 1⅛ 1¼ 1½ 1¾ 1⅞ 2⅛ 2⅜ 2¾ 3 3¼ 3⅝ 4 4⅜ 4¾ 5⅛ 5½ 5⅞ 6¼ 6¾ 7¼ 7⅝ 8⅛ 8⅝ 9¼ 9¾ 10¼ 10⅞ 0 0 0 ⅛ ⅛ ¼ ¼ ⅜ ½ ⅝ ¾ ⅞ 1 1⅛ 1⅜ 1½ 1¾ 2 2⅛ 2⅜ 2⅝ 2⅞ 3⅛ 3½ 3¾ 4 4⅜ 4¾ 5 5⅜ 5¾ 6⅛ 6½ 6⅞ 7⅜ 7¾ 8¼ 8⅝ 0 0 0 ⅛ ⅛ ⅛ ¼ ⅜ ⅜ ½ ⅝ ¾ ⅞ 1 1⅛ 1¼ 1½ 1⅝ 1¾ 2 2¼ 2⅜ 2⅝ 2⅞ 3⅛ 3⅜ 3⅝ 3⅞ 4¼ 4½ 4¾ 5⅛ 5½ 5¾ 6⅛ 6½ 6⅞ 7¼ 0 0 0 ⅛ ⅛ ⅛ ¼ ¼ ⅜ ⅜ ½ ⅝ ¾ ⅞ 1 1⅛ 1¼ 1⅜ 1½ 1¾ 1⅞ 2⅛ 2¼ 2½ 2⅝ 2⅞ 3⅛ 3⅜ 3⅝ 3⅞ 4⅛ 4⅜ 4⅝ 5 5¼ 5½ 5⅞ 6¼ 0 0 0 0 ⅛ ⅛ ⅛ ¼ ¼ ⅜ ½ ½ ⅝ ¾ ⅞ 1 1⅛ 1¼ 1⅜ 1½ 1⅝ 1⅞ 2 2⅛ 2⅜ 2½ 2¾ 3 3⅛ 3⅜ 3⅝ 3⅞ 4 4⅜ 4⅝ 4⅞ 5⅛ 5⅜ 0 0 0 0 ⅛ ⅛ ⅛ ¼ ¼ ⅛ ⅜ ½ ⅝ ⅝ ¾ ⅞ 1 1⅛ 1¼ 1⅜ 1½ 1⅝ 1¾ 1⅞ 2⅛ 2¼ 2⅜ 2⅝ 2¾ 3 3¼ 3⅜ 3⅝ 3⅞ 4⅛ 4⅜ 4⅝ 4⅞ 0 0 0 0 ⅛ ⅛ ⅛ ¼ ¼ ¼ ⅜ ⅜ ½ ⅝ ⅝ ¾ ⅞ 1 1⅛ 1¼ 1⅜ 1½ 1⅝ 1¾ 1⅞ 2 2⅛ 2⅜ 2½ 2¾ 2⅞ 3⅛ 3¼ 3½ 3⅝ 3⅞ 4⅛ 4 0 0 0 0 ⅛ ⅛ ⅛ ⅛ ¼ ¼ ⅜ ⅜ ½ ½ ⅝ ¾ ¾ ⅞ 1 1⅛ 1¼ 1⅜ 1½ 1⅝ 1¾ 1⅞ 2 2⅛ 2¼ 2½ 2⅝ 2¾ 3 3⅛ 3⅜ 3½ 3¾ 4 0 0 0 0 ⅛ ⅛ ⅛ ⅛ ¼ ¼ ¼ ⅜ ⅜ ½ ⅝ ⅝ ¾ ¾ ⅞ 1 1⅛ 1¼ 1⅜ 1½ 1⅝ 1¾ 1⅞ 2 2⅛ 2¼ 2⅜ 2½ 2¾ 2⅞ 3⅛ 3¼ 3⅜ 3⅝ 0 0 0 0 0 ⅛ ⅛ ⅛ ⅛ ¼ ¼ ⅜ ⅜ ½ ½ ⅝ ⅝ ¾ ⅞ ⅞ 1 1⅛ 1¼ 1⅜ 1½ 1½ 1⅝ 1¾ 2 2⅛ 2¼ 2⅜ 2½ 2⅝ 2⅞ 3 3⅛ 3⅜ 0 0 0 0 0 ⅛ ⅛ ⅛ ⅛ ¼ ¼ ¼ ⅜ ⅜ ½ ½ ⅝ ¾ ¾ ⅞ 1 1 1⅛ 1¼ 1⅜ 1½ 1½ 1⅝ 1¾ 1⅞ 2 2¼ 2⅜ 2½ 2⅝ 2¾ 2⅞ 3⅛ 0 0 0 0 0 ⅛ ⅛ ⅛ ⅛ ¼ ¼ ¼ ⅜ ⅜ ½ ½ ⅝ ⅝ ¾ ¾ ⅞ 1 1 1⅛ 1¼ 1⅜ 1½ 1⅝ 1⅝ 1¾ 1⅞ 2 2⅛ 2¼ 2½ 2⅝ 2¾ 2⅞ 0 0 0 0 0 ⅛ ⅛ ⅛ ⅛ ¼ ¼ ¼ ⅜ ⅜ ⅜ ½ ½ ⅝ ⅝ ¾ ⅞ ⅞ 1 1⅛ 1⅛ 1¼ 1⅜ 1½ 1⅝ 1¾ 1¾ 1⅞ 2 2⅛ 2¼ 2⅜ 2⅝ 2¾ 0 0 0 0 0 0 ⅛ ⅛ ⅛ ⅛ ¼ ¼ ¼ ⅜ ⅜ ½ ½ ½ ⅝ ⅝ ¾ ⅞ ⅞ 1 1⅛ 1⅛ 1¼ 1⅜ 1½ 1½ 1⅝ 1¾ 1⅞ 2 2⅛ 2¼ 2⅜ 2½ 0 0 0 0 0 0 0 0 ⅛ ⅛ ⅛ ⅛ ¼ ¼ ¼ ¼ ⅜ ⅜ ⅜ ½ ½ ½ ⅝ ⅝ ¾ ¾ ⅞ ⅞ 1 1 1⅛ 1¼ 1¼ 1⅜ 1½ 1⅝ 1⅝ 1¾ ANSI A190.1-2012 4.2.2 Tolerance for Camber or Straightness – The tolerances are applicable at the time of manufacture without allowances for dead load deflection. Up to 20 ft., the tolerance is plus or minus ¼ in.. Over 20 ft., increase tolerance ⅛ in. per each additional 20 ft. or fraction thereof, but not to exceed ¾ in. The tolerances are intended for use with straight or slightly cambered members and are not applicable to curved members such as arches. Boise Cascade EWP • BOISE GLULAM® Product Guide • 005/23/2013 Technical Items ADHESIVES 5 CHECKING BOISE GLULAM beams are manufactured with exterior-grade or wet-use adhesives that comply with all recognized national glulam standards. The purpose of exterior-grade adhesives is to ensure that the design values of the beams are not compromised when the beams are directly exposed to the weather during construction. Though wet-use adhesives are required when glulam beams exceed a moisture content of 16% for extended periods of time after installation, the beams still must be protected from exterior exposure. (For applications where moisture content may exceed 19%, see Preservative Treatment.) ® Checking occurs naturally in timber when wood fibers dry. As the outer fibers lose moisture and attempt to shrink, they are restrained by the fiber in the inner portion of the beam, which loses moisture at a much slower rate. Rapid drying increases the difference in moisture content between the inner and outer fibers and thus the chances for checking in the timber member. To minimize the potential for checking, BOISE GLULAM ® is produced from special grades of lumber specifically dried to less than 16% moisture content. Example of Checking (ANSI A190.1-2012 Standard for Wood Products Structural Glued Laminated Timber) See page 6 of this guide – "Exposed Applications for Glulam” HANDLING & STORAGE Water-resistant wrapping is often specified to protect beams from moisture, soiling, and surface scratches during transit and job-site storage. Because exposure to sunlight can discolor beams, opaque wrappings are recommended. Beams can be wrapped individually or by the bundle. In applications where appearance is especially important, individual wrapping should be left intact until installation to minimize exposure to job-site conditions. Beams are commonly loaded and unloaded with forklifts. For greater stability, the sides of the beams, rather than the bottoms, should rest on the forks. Supporting extremely long beams on their sides, however, can cause them to flex excessively, increasing the risk of damage. Use multiple forklifts to lift long beam members. A level, well-drained, covered storage site is recom mended. Keep beams off the ground, using lumber blocking, skids, or a rack system. Keep beams level. The wrapping on beams should be left in place to protect them from moisture, soiling, sunlight, and scratches. For long-term storage, cut slits in the bottom of the wrapping to allow ventilation and draining of any entrapped moisture. Proper ventilation and drainage will reduce the likelihood of water damage, staining, and the start of decay.

Contact Boise Cascade EWP Engineering for any further technical guidance. FIELD NOTCHING & DRILLING Glulam beams are generally designed for applications where they will be highly stressed under design loads. For this reason, field modifications such as notching, tapering, or drilling may only be made only after approval has been given by the project’s design professional of record and/or Boise Cascade Engineered Wood Products representative. For the proper location of smaller holes, please refer to page 9. Analysis of notches and tapered end cuts on BOISE GLULAM® beams may be performed by a qualified user of BC CALC®, Boise Cascade EWP's engineered wood sizing software. Technical Items 6 DIMENSIONAL TOLERANCES The tolerances permitted at the time of manufacture per ANSI Standard A190.1-2012 are as follows: Width – Plus or minus 1/16" of the specified width. Depth – Plus ⅛" per foot of depth. Minus 3 /16", or 1 /16" per foot of depth, whichever is larger. Length – Up to 20 feet – Plus or minus 1/16" Over 20 feet – Plus or minus 1/16" per 20 feet of length. Note that the above tolerances do not apply to rough sawn textured beams. Camber or Straightness – Tolerances are intended for use with straight or slightly cambered beams. The tolerances permitted at the time of manufacture, without allowance for dead load deflection, are as follows: Up to 20 feet – Plus or minus ¼". Over 20 feet – Add ⅛" per each additional 20 feet or fraction thereof, but not to exceed plus or minus ¾". Squareness – The tolerance of the cross section shall be within plus or minus ⅛" per foot of specified depth, unless a specially shaped beam is selected. EXPOSED APPLICATIONS FOR GLULAM BOISE GLULAM® beams are intended for applica tions where mold, decay, and/or insect attack are not concerns. For conditions where glulams are perma nently exposed to the weather, have direct ground or concrete contact, or are exposed to significant mois ture from condensation or other sources, preservative treatment is required as specified by applicable building codes. For information on different treat ments for specific applications, please consult a wood treater or treating association. Please note that when glulams are treated, design values may be affected. All field cuts – including notches, end cuts, and holes – should be performed before the glulam beam is treated. All fasteners used with treated glulam beams must be resistant to corrosion from moisture. Consumer Information Sheets that detail proper use and handling of products with the specified treatments should be obtained from the treater for proper use and handling of products with the specified treat ments. In addition, Material Safety Data Sheets (MSDS) and OSHA-required hazard labels provided with each preservative should be reviewed. Please note that when glulams are treated and installed in exterior applications, design values shall be adjusted per building code provisions. Durable species glulams such as Port Orford Cedar are readily available and provide alternative product for exposed applications. This may be a good option for your top appearance applications. See Durable Species Flyer for additional information on options Consult your local distributor for availability. FIRE RESISTANCE BOISE GLULAM® beams, like many other wood products, have advantageous fire-endurance properties. Unlike steel that loses a large percentage of its strength when exposed to typical temperatures during a fire, wood beams char on the surface. Charring forms a self-insulating surface layer when wood is exposed to flame or relatively high temperatures. The wood below this layer retains its structural properties during a fire. Most solid wood members, including BOISE GLULAM® beams, char at a rate of approximately 1½ inches per hour. BOISE GLULAM® may be special ordered to create a beam with a one-hour fire rating. In this beam specification, an additional high grade tension lamination replaces a core lamination in the manufacturing process. The project's design professional of record shall specify this type of fire-resistance requirement. Larger glulam beams may be utilized in heavy timber construction, and a fire-resistance classification where exposed beams are designed to maintain a specified strength level for a specified duration during a fire. For further information on heavy timber construction, please refer to Heavy Timber Construction - Wood Construction Data #5, American Wood Council. The adhesives used in BOISE GLULAM® beams do not reduce the fire-endurance properties of the wood material. When compared to wood, the adhesives have a higher ignition temperature and char in a very similar manner. When burned, the adhesives do not increase smoke toxicity. See Boise Cascade Fire Design & Installation Guide for further design and detailing information. For further information on fire-resistance design, please contact Boise Cascade EWP Engineering.

Effective column length is equal to actual column length. Allowable loads are based on one-piece column members used in dry service conditions. Allowable loads are based on an eccentricity value equal to 0.167 multiplied by the column thickness or width (worst case). Allowable loads are based on axial loading columns using the design provisions of the National Design Specification for Wood Construction (NDS), 2001 edition. For side or other combined bending and axial loads, use BC COLUMN software to analyze such conditions. See below for allowable design stresses. Load values are not shown for short lengths due to loads exceeding common connector capacities. Load values are not shown for longer lengths if the controlling slenderness ratio exceeds 50 (per NDS). It may be possible to exceed the limitations of the table by analyzing a specific application with the BC COLUMN software.
