These drawings and comments are for general information only, and EIMA specifically disclaims any design or construction intent or responsibility. THERE ARE NO WARRANTIES, EXPRESS OR IMPLIED, ISSUED OR MADE BY EIMA IN CONNECTION WITH THESE DRAWINGS AND COMMENTS OR REGARDING THE USE OF EIFS. These drawings are not intended and should not be used as a substitute for the EIFS system manufacturer's specifications and recommended construction practices and/or for professional building design services. The specification, design and construction of all EIFS must comply with local building codes and standards, applicable compliance reports and the individual manufacturer's system requirements. These requirements differ materially. Only the EIFS manufacturer or design professional can furnish specifications, details, drawings, and construction practices to be followed for actual construction and use of an EIFS product and for compliance with applicable local building codes and construction practices. The successful installation and performance of EIFS cladding is dependent upon the proper design and construction of the adjacent materials and systems of the structure. For these reasons, only a licensed and qualified design professional can create and issue specifications, drawings and details for actual or prospective construction or renovation using EIFS. These drawings and comments apply only to new construction beginning in 2000, and are not intended for inspections, retrofit or repair. These drawings are not intended as an exclusive method for achieving desired performance. Alternative configurations may achieve equal or better performance. These drawings and comments apply only to complete EIFS products as specifically defined in the current edition of EIMA Classification Paper.

Guide to EIFS Construction EPS BOARD LAYOUT Fig. 1 EPS BOARD LAYOUT The Expanded Polystyrene Board (EPS) is placed on the wall in a running-bond pattern. The first row is generally half width to minimize EPS board joints from lining up with sheathing joints. To decrease base coat stress at corners of wall openings, EPS boards are “L” cut. Insulation Board “L” Cut At Corners of Wall Penetrations Insulation Board Applied In a Running Bond Pattern Interlock Edges of Insulation Board At Corners Starter Row of Insulation Board Used to Offset Insulation Board Joints From Sheathing Board Joints...

Guide to EIFS Construction WINDOW - NAILING FIN, CONCEALED SILL PAN Refer to the window manufacturer’s guidelines for specific installation requirements. Framing Substrate Insulation Board Adhesively Or Mechanically Attached To Wall Some finned windows are considered “self-flashed”. However, a careful examination should be made of the joinery between the head, jamb and sill fins to ensure continuous protection against air and water passage. Any breach in the window’s outer cladding should be resolved with additional flashing and/or sealant. Consult the window manufacturer for installation...
