Designation:E251109Standard Guide forDetailing of EIFS-Clad Wall Assemblies1This standard is issued under the fixed designation E2511;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This guide describes the types of project-specific con-struction conditions that need to be communicated by means ofdrawings(“details”)for the purpose of constructing ExteriorInsulation and Finish System(EIFS)-clad wall assemblies.EIFS manufacturers provide basic details for the installation oftheir materials and interface with adjacent materials.Thesedetails are generic and,in many cases,do not apply to specificproject conditions.1.2 This guide addresses only the EIFS itself and theinterface between the EIFS and the materials immediatelyadjacent to the EIFS;it does not address all parts of the wallassembly.1.3 Not all possible construction detail conditions are ad-dressed by this guide.Identify and provide details for allconstruction conditions that exist on a specific building.1.4 This guide is intended to supplement but not supersedeinformation from the EIFS manufacturer about how theirspecific product should be detailed,nor to supersede technicalproduct acceptance reports or the code requirements of regu-latory authorities.1.5 The values stated in inch-pound units are to be regardedas standard.No other units of measurement are included in thisstandard.1.6 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2E631 Terminology of Building ConstructionsE2110 Terminology for Exterior Insulation and Finish Sys-tems(EIFS)3.Terminology3.1 For general terminology regarding EIFS and building ingeneral,see Terminology E2110(for EIFS terms)and Termi-nology E631(for buildings in general).3.2 Definitions of Terms Specific to This Standard:3.2.1 detail,na graphic representation of the manner inwhich building materials are to be constructed as an assembly.4.Significance and Use4.1 This guide is for use by individuals and entities involvedwith the design and specification of EIFS details for a specificbuilding.4.2 This guide can be applied to both EIFS-clad barrierwall assembly and EIFS-clad wall with drainage.4.3 This guide can be applied to new and existing EIFSbuildings,prefabricated versus on-site installed EIFS,andresidential and commercial EIFS buildings.4.4 This guide is not meant to replace the types of informa-tion normally present in text format in a projects specifica-tions.4.5 This guide is not applicable to EIFS materials used innon EIFS applications,such as a topcoat for other basematerials like traditional Portland cement plaster(stucco)andconcrete.5.Form of Details5.1 Draw details using a drafting style,and at a scale,whichmakes clear the design of the final construction,including thereinforcing mesh,adhesive layers,and location of the finish.5.2 If necessary,include the sequence by which the assem-bly is constructed in the details,such as by means of a 3-Dstep-by-step sequence of drawings,or some indication of theorder in which the detail is assembled.5.3 Present details in drafting styles(2-D or 3-D,such asisometric,oblique,perspective,etc.)that are consistent withthe need to appropriately convey how the various parts of theconstruction fit together.1This guide is under the jurisdiction of ASTM Committee E06 on Performanceof Buildings and is the direct responsibility of Subcommittee E06.58 on ExteriorInsulation and Finish Systems(EIFS).Current edition approved April 1,2009.Published April 2009.DOI:10.1520/E2511-09.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 6.Detailing Principles6.1 The following principles apply when designing details.6.1.1 Terminate the perimeter of the EIFS by wrapping thebase coat around the edge of the insulation,either by bondingit to the substrate behind the insulation(called backwrapping),or bonding it to the edge of the opening or edge(if an openingor edge is present),or by using trim that is approved by theEIFS producer for use with their EIFS products.6.1.2 Adhere sealants to the base coat,not the finish coat.Use sealant type acceptable to the EIFS producer and sealantproducer.Use sealant primer,if required by the EIFS producerand sealant producer.Use closed cell type backer rod.6.1.3 Obje
