This document outlines key quality control points for builders and installation contractors using EIFS cladding for residential construction.

The purpose of the document is to establish a Quality Plan for the construction process that results in long-term performance of EIFS-clad dwellings. The construction process involves selecting an EIF system that can perform as intended, verifying that the building incorporates a properly installed substrate, weather barrier, flashing, and sealant and is suitable for EIFS installation. The EIFS installation process includes installation of the insulating board, reinforced base coat, and finish coat.

The aim is to prevent construction defects, ensure compliance with manufacturer’s requirements, and reduce variation.

The following items are important factors to consider before selecting and installing EIFS:

  • The EIF system must meet applicable regulatory requirements.
  • The EIF system must be accepted by underwriters of builders risk insurance.
  • The EIF system must be capable of performing for the intended application and meet the performance attributes described herein.
  • EIFS materials from one manufacturer’s system must not be substituted for materials from another manufacturer’s system.
  • Building designs must not exceed limitations specified by the EIFS manufacturer.
  • Workmanship requirements must be clearly defined.
  • Craftspersons must be trained and qualified to perform the work.
  • EIFS contractors must be approved by the EIFS manufacturer for the system to be installed.
  • The installation contract must define the responsibilities of both the builder and trade contractors and outline the sequencing of work.
  • Purchased trade contractor services, products, and materials must conform to specified requirements of the EIFS manufacturer.
  • Selection and installation of building materials, such as flashing, weather barriers, windows, and EIFS must be integrated in accordance with the manufacturers' specifications.
  • The EIFS contractor must have an approved crew leader on the jobsite during installation.
  • The EIFS contractor must conduct a job readiness inspection before installation and issue corrective actions to the builder when nonconformances are identified.
