1、Designation: E2568 17Standard Specification forPB Exterior Insulation and Finish Systems1This standard is issued under the fixed designation E2568; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number

2、 in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers PB Exterior Insulation andFinish Systems (EIFS) defined as an exterior, non-bearing wallcovering providing a weathe

3、r-resistant exterior wall envelopeon walls required to be combustible or noncombustible, fire-resistance-rated or nonfire-resistance-rated. Further, PB EIFSis a system described as being applied over expanded polysty-rene or polyisocyanurate insulation board, an adhesive ormechanical attachment of t
