These are the major sales appeals of two new U.S.G. Solid Partition systems; the latest in the New Per spectives series of drywall advances for commercial construction. Developed to divide high-cost commer cial and industrial space with minimum reduction of usable floor area, the USG 2-in. Solid and Double Solid Gypsum Drywall Partitions appeal strongly to architects and building owners (see chart below). Earlier occupancy is also assured by economical drywall construction which eliminates moisture prob lems encountered with other partitions. Simplicity of design and ability to receive any decoration are ad vantages that make both USG Solid Partitions easily adaptable to any decor. Conventional joint treatment is used to finish both partitions. The USG 2-in. Solid Partition is an incombustible, non-load-bearing wall which provides an average 36 db sound transmission loss rating and 1 ^ or two-hour fire rating, depending upon type of facing. The par tition is constructed in place by laminating face layers continued USG 2-IN. SOLID PARTITION 1 AS FIRST STEP in erection, custom metal runners ' are attached to ceiling and door. 2 l-IN. COREBOARD is cut to fit door frame before being installed in floor and ceiling runners. 3 CORE SPACER CUP centers coreboard in runners to insure accurate alignment of vertical tongue-and-groove edges. 4 PERF-A-TAPE JOINT COMPOUND is applied to back of Sheetrock face layers prior to lamination to coreboard. 5 WAUBOARD SCRAPS may be temporarily nailed at third points along vertical joints to insure proper alignment and adhesion of face layers. Nail holes are covered in taping. 6 MORE SPACE MEANS MORE INCOME: Diagonal line shows square feet of floor space gained per 100 lin. ft. of USG 2-in. Solid Partition over other partitions. Multiply this figure by number of 100 lineal feet units in a job to determine total gain in usable floor space. Multiply total gain by monthly rental per square foot to determine increase in monthly rental received.
