Scope*1.1 This practice covers the minimum requirements andprocedures for field or prefabricated applic
3、ation of Class PBExterior Insulation and Finish Systems (EIFS) and EIFS withDrainage. Class PB EIFS are systems applied over insulationboard, in which the base coat ranges from not less than116 in.(1.6 mm) to14 in. (6.4 mm) in dry thickness, depending uponthe number of nonmetallic reinforcing mesh l
4、ayers encapsu-lated in the base coat (see Specification E 2568). The base coatis then covered with a finish coat of varying thickness in avariety of textures and colors. EIFS with Drainage provides amechanism to drain incidental moisture1.2 The values stated in inch-pound units are to be regardedas
