Book Overview

ANSI/EIMA 99A – 2017 embodies the minimum requirements for specifying and installing Exterior Insulation and Finish Systems (EIFS) and EIFS with Drainage. The generic materials, details, and design considerations for EIFS and EIFS with Drainage are described in this standard. For specifications, application instructions, and details specific to a particular EIF System, consult the EIFS manufacturer’s product literature. In addition, care has been taken to incorporate the reference documents that constitute provisions of this American National Standard. The Annex contained in this standard is considered part of the standard.

Key Features & Benefits

Product Checkbox
Comprehensive Coverage:
  •  Scope and Purpose

    The standard outlines the minimum requirements for specifying and installing EIFS and EIFS with drainage. It covers generic materials, details, and design considerations for these systems. However, for specifications, application instructions, and details specific to a particular EIFS, users are advised to consult the manufacturer’s product literature. The annex included in the standard is considered an integral part of the document. 

    2. EIFS Components and Systems

    • EIFS with Drainage: This system incorporates a means for moisture to exit the wall assembly, reducing the risk of water-related issues. It includes components such as insulation board, base coat, reinforcing mesh, finish coat, and a drainage plane.
    • EIFS without Drainage: Traditional EIFS systems that do not have a dedicated drainage path. These systems require meticulous installation to prevent moisture accumulation behind the cladding.

    3. Design and Installation Guidelines

    • Materials: Specifies the types and properties of materials used in EIFS, including insulation boards (e.g., expanded polystyrene), base coats, reinforcing meshes, and finish coats.
    • Attachment Methods: Details the methods for attaching insulation boards to substrates, ensuring secure and stable installations.
    • Drainage Considerations: For EIFS with drainage, outlines the design and installation of drainage planes to facilitate moisture movement and prevent water accumulation.
    • Interface with Other Building Components: Provides guidance on integrating EIFS with other building elements, such as windows, doors, and roof systems, to maintain continuity and performance.

    4. Performance Criteria

    • Thermal Performance: Ensures that EIFS systems provide adequate insulation to meet energy efficiency requirements.
    • Durability: Addresses the longevity of EIFS components under various environmental conditions, including resistance to weathering, impact, and thermal cycling.
    • Moisture Management: Emphasizes the importance of proper moisture control to prevent issues like mold growth and material degradation.
    • Fire Resistance: Specifies fire performance criteria, including compliance with standards such as ASTM E 119 and NFPA 285, to ensure safety in case of fire.

    5. Compliance and References

    The standard incorporates provisions from various reference documents, including ASTM standards and building codes, to ensure comprehensive coverage of relevant requirements. Users are encouraged to consult these references for detailed information on specific aspects of EIFS design and installation.

Practical Application:
  • Design & Specification

    • Architects and engineers use it to design wall assemblies, insulation thickness, drainage, and weather-resistive barriers.

    • Ensures systems meet performance, durability, and moisture-management requirements.

    2. Material Selection

    • Guides contractors and specifiers in choosing approved insulation, base coats, finish coats, mesh, sealants, and flashings.

    3. Installation

    • Provides step-by-step criteria for surface prep, mesh embedding, flashing, and sealing.

    • Ensures consistent, defect-free construction.

    4. Water Management & Drainage

    • Distinguishes barrier vs. drainage EIFS.

    • Guides weep systems, flashing, and drainage planes to prevent water intrusion, mold, and rot.

    5. Inspection & Quality Assurance

    • Used by inspectors and project managers to verify tolerances, finish quality, attachment, and proper sealing.

    6. Problem Prevention & Maintenance

    • Helps prevent common issues like cracking, delamination, thermal bridging, and moisture damage.

    • Supports evaluation and corrective actions for existing EIFS systems.

Product Checkbox
Licensing Exam Preparation:

Understanding System Requirements

  • Candidates learn wall assembly, insulation, drainage, and moisture-control rules.

  • Helps answer questions about barrier vs. drainage EIFS, flashing, and water management.

2. Material & Component Knowledge

  • Teaches which insulation, base coats, finish coats, reinforcing mesh, sealants, and flashings are acceptable.

  • Prepares for questions about material specifications and compatibility.

3. Installation & Construction Criteria

  • Step-by-step installation rules help candidates visualize proper construction procedures.

  • Supports answering scenario-based exam questions on installation, surface prep, or defect prevention.

4. Inspection & Quality Assurance

  • Provides knowledge for questions about tolerances, finish quality, proper attachment, and sealing.

5. Problem Prevention & Maintenance

  • Exam questions often test understanding of common EIFS problems, like delamination, cracking, or water intrusion, and how to prevent them.

Product Checkbox
Visual & Organizational Tools:

Sectioned Layout

  • Organized by topic: system types, materials, installation, drainage, inspections, and maintenance.

  • Numbered headings and subheadings allow quick navigation during study or on-site reference.

2. Tables & Charts

  • Summarizes:

    • Material properties and compatibility
