For proper installation of Exterior Insulation Finish Systems (EIFS), what must be followed?

For the proper installation of Exterior Insulation Finish Systems (EIFS), following the manufacturer instructions is essential. Manufacturer guidelines provide specific technical details, recommendations, and standards that ensure the EIFS is installed correctly to function as intended. These instructions often include information about the types of materials to be used, application techniques, temperature and humidity conditions for installation, and necessary preparation of surfaces. Adhering to these specifications helps prevent issues such as moisture intrusion, which could lead to mold growth or structural damage over time.

While local health codes, builders' instructions, and drywall installer's instructions may contain relevant information, they do not specifically address the unique requirements essential for EIFS installation. Local codes are crucial for overall compliance with regulations, but they are typically broader and may not cover the specificities needed for EIFS. Similarly, builders' and drywall installers' instructions may focus on general building practices rather than the detailed requirements that are specially tailored to EIFS systems. Therefore, relying on manufacturer instructions is the correct approach to ensure proper installation and performance of the system.
