PRODUCT BULLETIN 1968-1 A.I.A. File No. 12-B/12-B-2 H B 0 1U U3 / Exterior protection of buildings has been a United States Gypsum specialty ever since the company began manufactur ing roofing products, in 1933. USG asphalt roofing offers the protection of rated fire resistance plus the two other character istics most important to architects--beauty, expressed in harmonious, lasting colors, and durability, promising mini mum maintenance for years to come. Value and dependability are built into these products through the unique U.S.G. quality control standards. Asphalt shingles, for example, are made from top-grade felt that is asphaltsaturated to resist aging and coated with a special stabilized asphalt. Color-fast granules are embedded in the heavy bodied coating to form a weather-protective shield. A second coating covers the back of the shingle--all carefully controlled to conform to rigid specifications. These manufacturing safe guards are backed by regular testing and constant product improvement at the U.S.G. Research Center, largest and best equipped in the industry. The wide diversity of types, styles and colors makes it possible to satisfy almost every asphalt roofing requirement. U.S.G. offers differing product lines, tailored to market preferences, in three large geographic areas: Northeast (states north and east of North Carolina, Kentucky and Ohio)--2-tab Class A and 300-lb. triple coverage asphalt shingles; also 3-tab shingles, both conventional and self sealing, in 300-lb., 265-lb. and 235-240-lb. weights. Upper Midwest (Iowa, Minnesota, North Dakota, South Dakota, Nebraska, Wisconsin, northern Illinois, northern Michigan, eastern Montana)--3-tab asphalt shingles in 300-lb., 265-lb. and 235-lb. weights and seLf-sealing type; also double coverage interlocking shingles. West (California, Oregon, Washington, Idaho, Utah, Nevada, Arizona, western Montana, Hawaii)--20, 15 and 10-year bonded built-up roof assemblies; 3-tab asphalt shingles in 300-lb. and 235-lb. weights and self-sealing type. USG asphalt roofing is made to work together, economically and compatibly, with other USG exterior materials--poured gypsum concrete roof decks, precast gypsum roof plank, wood fiberboard roof insulation, and wood fiberboard in sulating roof deck (West only). The benefit of dealing with a single manufacturer is extended further by incorporating into the job such additional USG exterior products as gypsum or insulating sheathing, exterior stucco, mineral siding, mason's lime, aluminum louvers, and paint products. types and functions Firecode Class "A" Shingles--just introduced in North east region, massive twin-tab shingles with highest UL fire rating, applying to three different grades. They also carry UL Wind-Resistant rating because of self-sealing feature--12 spots of high-strength adhesive placed across each shingle to bond firmly to previous course. Available in choice of weights: A-15, 220 lbs.; A-20, 240 lbs.; A-25, 295 lbs. All offer economies and superior performance versus many competitive shingles as a result of new manufac turing process. Asbestos and mineral fibers are blended into thick asphalt coating. Offered in color line of solids and blends specially designed for architectural applications. Sealco Self-Sealing Strip Shingles--wherever the re quirement is for maximum wind protection or for application to low-pitched roofs, Sealco self-sealing shingles offer many advantages over ordinary shingles. Sealco comes with 12 spots of high-strength adhesive placed across each shingle, automatically bonding the tabs to the nailed-down portion of the previous course. This self-sealing action takes place at normal roof temperatures, not limited to extremes of summer heat. Sealco carries the U.L. Wind-Resistant label. The placement of Sealco sealant spots at intervals across the shingle helps the roof to breathe, and prevents.trapping of condensation beneath the tabs. Unlike ordinary shingles, no hand sealing is needed on the lower ^pitches down to 2/12. Rugged, fire-resistant Sealco shingles are available in a wide range of beautiful solid and blended colors. Fortified-300 Strip Shingles--one of the finest custom shingles ever made--ideal for churches, institutions, public buildings as well UNITED STATES GYPSUM page 1 STATES i10G8- -1 & i H asphaltic ^ bit umi nous as custom-built homes. Almost 30% heavier than standard strip shingles, designed to give maximum rugged wear wherever supreme roof quality is desired. This fire-resistant 300-lb. shingle is built from extra-heavy felt, given a super-thick asphalt coating and a deep layer of selected granules. The result is a rich, massive appearance with deep shadow lines created by the shingle's extra thickness. Fortified-300 offers long-run economy because of its built-in durability to resist high winds, sun, rain and snow. Available in popular blended colors, textures and standard surfaces; also with the SEAJLCO self-sealing feature(above)in some areas. USG 235-lb. Square Butt Strip Shingles--the all-time favorite in roofing shingles of standard weight and design, offering superior quality at economical cost. These classic 12' three-tab shingles blend well with both traditional and contemporary styles of architecture, harmonizing with the texture and tone of exterior walls. Square Butts (identified as Cascade Shingles in West) are available in the widest range of rich-toned colors of any USG shingle--in solid, blended and pastel shades. Rock-hard mineral granules give them a lasting full-color brilliance. For the extra protection and longer life of a triple-coverage roof, USG Square Butts may be applied with a 4-in. exposure in place of the standard 5-in. exposure--done by using built-in alignment guides and increasing quantity by 25%. 2-Tab SEALCO Strip Shingles (available in Northeast only)--huge 18' tabs. 50% wider than in 3-tab roofing, accentuate horizontal roof lines desired in contemporary de sign. Sealco self-sealing features provide maximum wind protection, permit use on low-pitched roofs. Carries U.L. Wind-Resistant label. USG Giant Strip Shingles (available in Northeast and Upper Midwest)--265-lb. super-thick shingles for custom appearance and long service. Conventional three-tab design, in range of solid, blended and pastel colors; also available with the Sealco self-sealing feature in some areas. llll Specialty Shingles, available in areas of market demand, include lock shingles for high-wind areas--double coverage and standard Grip-Lock, standard-weight Imperial-Lock, and lighter weight Arro-Lock shingles. Others are 10' Thatch and Starcraft shingles for distinctive appearance, individual Dutch Lap and Angle Lap shingles, and Hexagon shingles for re-roofing and utility needs.

Good Application Practices--when failure of asphalt roofing occurs early in service, the cause is usually poor application or incorrect use of materials. These points should be checked: (1) Rigidity of deck. If not rigid, movements may affect the lay of the roofing. Wood roof deck boards should be properly seasoned 1 x6's or exterior grade plywood. (2) Ventilation. Condensation can cause warping and buck ling of shingles. This is avoided by proper ventilation-- minimum of 1 sq. ft. of free area for every 300 sq. ft. of attic area is recommended. Balanced system should be used, with 50% of louver capacity on or near the roof ridge and remain ing 50% divided equally between overhangs. (3) Choice of Shingles. Generally the heavier the shingle, the greater its durability. Self-sealing shingles--such as Firecode and Sealco brands by U.S.G.--are recommended for roof pitches of 4/12 or more. For application on roof slopes down to 2/12, special instructions are available. (4) Nailing. Nails of proper size, length and location should be used for each application (see Specifications). (5) Accessories. Flashing, valleys, rakes, ridges, hips and eaves must be watertight, gutters and downspouts adequately sized for maximum drainage loads. page 2 B8010 0373 f c i t c L USG Asphalt Roofing Products C c c!
