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.
Adhere sealants to the base coat,not the finish coat.Use sealant type acceptable to the EIFS producer and sealant
producer. Use sealant primer, if required by the EIFS producerand sealant producer. Use closed cell type backer rod.
Objects are not to be fastened to the EIFS. Fastenobjects through the EIFS into a structural material in the
substrate. Provide spacers within the EIFS insulation layer toprevent crushing the EIFS when mounting hardware is tightened. Seal all fastener holes through the EIFS, using sealant,gaskets， or other suitable material.
Shield the EIFS from heat producing devices thatcould damage the EIFS, such as transformers,flues, chimneys,lights，pipes containing high temperature liquids, hot air vents,etc.
Provide working sealant filled expansion joints be-tween prefabricated EIFS panels,at floor lines in wood framebuildings, where expansion joints occur in the substrate, wherethe substrate type changes，and where significant movementoccurs behind the EIFS.
Detail the attachment of the EIFS, and the supportingsubstrate system to withstand applicable wind loads for theproject.
Evaluate the use of a particular EIFS on a buildingrequired to be of noncombustible construction in terms of codecompliance for insulation type, insulation thickness, insulationdensity,acceptable substrate，EIFS attachment method,andEIFS coating types.
Provide detail drawings of the construction conditionsthat are present on the specific building.The list below is notall-inclusive, but it gives representative examples of conditionsto be aware of and to provide for.Terminations of the EIFS, such as: at the top, bottom,and side (ends) of EIFS wall assemblies; and at roofs，roofrakes，eaves，parapets，end-of-EIFS-clad wall conditions,openings，and bottoms of EIFS walls near grade,decks，andwalkways. Openings through the EIFS,such as: at windows,doors,louvers,vents,and large pipes or ducts.ASTM E2511 pdf download.
