    (Specifier Note: The purpose of this guide specification is to assist the specifier in cor-rectly specifying a specialty graphic interlayer for laminated glass products. The spe-cifier needs to edit the guide specifications to fit the needs of the specific project. Con-tact a SentryGlas? Expressions? Licensee Representative to assist in making the appro-

    priate interlayer selections; contact a glazing fabricator for additional assistance in se-lection of glazing products. Throughout the guide specification, there are Specifier Notes to assist in the editing of the file. The term Architect is used throughout these guide specifications, as a guide and may be edited to read “Design Professional”,” En-

    gineer”, “Owner” or other appropriate designation as required for specific project.

    Laminated glass consists of two or more lites of glass bonded together with an interlayer of polyvinyl butyral (PVB) sheet, which is bonded to glass lites under heat and pressure

    ? TMin an autoclave. SentryGlasExpressions interlayers are clear PVB sheets printed us-

    ing high-resolution ink jet printers with specially formulated ink. A soft white or translu-cent white interlayer backing can be specified to create additional translucency in the laminate.

    References have been made within the text of the specification to MasterFormat 2004 Section numbers and titles, specifier need to coordinate this numbers and titles with sections included for the specific project. Brackets [ ]; “AND/OR”; and “OR” have been used to indicate when a selection is required.

     Fabricators (laminators) purchase interlayers from which various laminated glass prod-

    ucts are produced. Laminated glass can be incorporated into insulating glass units for improved thermal and acoustical properties, contact a glass fabricator for assistance.

    The focus of this guide specification is on the interlayer. Section needs to be coordi-nated with the laminated glass manufacturer, the project requirements and other product information for accuracy.)

    (Specifier Note: Coordination with a licensed manufacturer of SentryGlas? Expressions?

    ? is critical in utilizing SentryGlasExpressions? for a project. Contact a licensee early in the design process. Image files are best scaled at 1:10 for easy handling; however, other scaling factors are acceptable. For high-quality printing, raster image files generally should be 150-200 pixels per inch at final production size. Electronic files sizes should be generally e not more than 250 MB, but greater than 50 MB. Acceptable formats include PC- or Macintosh-based Photoshop, Illustrator, and most other common

    ? image originating programs. Digital printing onto SentryGlasExpressions? interlayer is

    performed using large format ink jet equipment capable of achieving print resolution of up to 1,440 dots per inch.)

    ? c. Image: Graphic image has been coordinated with the SentryGlas
