All patterns of Motjf'd Acoustone. except Linea, are 12'xl2' units; Vtff thick: with square edges only. Linea pattern is available in 12*x241' units only; V* thick; with square edges only. light reflection ... Motjf'd Acoustone painted white has a light reflection coefficient of71%, as tested by A.M.A. Laboratories. DESIGNS.. .The standard patterns illustrated in this folder provide the designer with a wide range of beautiful and unusual decorative effects. Custom designs can also be produced to meet individual requirements. METHODS OF INSTALLATION . . . MOTIF'D ACOUSTOKE may be adhesively attached to an existing ceiling or to a suspended gypsum board base. Motjf'd Acoustone in 12'xl2' units may also be mechanically suspended on the Concealed Z-Spline System. Motif'd Acoustone in 12*x24' units (Linea only) may be me chanically suspended on the E-Z-S System. function and utility SOUND ABSORPTION ... The adhesive applic. cion is desig nated as the "No. 1 mounting," and the suspended acoustical units on the Z-Spline System are designated as the "No. 7 mounting." (See Technical Data for sound absorption values.) colors...The face side of Motif'd Acoustone is painted at the factory with a full-finish coat of either white or ivory paint. Other standard pastel colors shown on the current USG Texoute* Standard Color Selector are obtainable on special order. washability* .. Factory-painted Motjf'd Acoustone may be washed with a damp sponge; or cleaned with a v: cuum cleaner, chemical rubber sponge (used dry) or wallpaper cleaner of either putty or paste type. Accidental spotting or soiling can usually be removed by this method before over-all redecoration is necessary. PAINTABILITY... Motjf'd Acoustone mineral acoustical tile may be brush- or spray-painted many rimes without Joss of sound absorption at 300 cycles per second, or in the Noise Reduction Coefficient. Oil. casein, resin emulsion or spirit-thinned paints may be used with normal painting procedures. Latex paints are not recommended. .TheRESISTANCE TO SOILING AND "BREATH I NO**. . painted finish of Motif'd Acoustone resists soiling, and limits objectionable air travel ("breathing") through the face of the tile.
