Exterior Insulation and Finish Systems (EIFS) have transformed the construction industry by offering an energy efficient, cost effective and visually appealing alternative to conventional building methods. A vital element that contributes to the robustness and longevity of EIFS is the utilization of fiberglass mesh. When it comes to high traffic areas and ground floors, we recommend employing a 20oz heavy mesh for added reinforcement. This comprehensive guide explores the intricate aspects of the Exterior Insulation and Finish system wall assembly, with a specific focus on the significance of heavy mesh.
The Significance of Heavy Mesh in an EIFS Wall Assembly:
Incorporating heavy mesh into EIFS wall assembly holds immense importance for various reasons. Primarily, it bolsters the system’s strength and durability, rendering it more resistant to impacts and potential damage. This attribute proves especially critical in areas experiencing heavy foot traffic or ground level sites where impact risks are elevated. Additionally, the presence of heavy mesh acts as an additional layer of reinforcement beneath the standard mesh, elevating overall integrity within the Exterior Insulation and Finish System wall assembly structure.
EIFS Wall Assembly: A Step-by-Step Guide
Here is a detailed step by step guide on how to assemble an EIFS wall;
The liquid moisture barrier Flashing System: This system acts as the first line of defense against air, moisture and weather. It is installed at all wall openings to ensure protection.
- The liquid moisture barrier Air/Water Resistive Barrier Coating: This coating serves as a barrier against air and water, providing an additional layer of protection.
- Adhesive/Drainage Medium: This layer plays a crucial role in adhering the insulation to the wall while facilitating effective moisture drainage.
- Pre Based Starter Board: Acting as the foundation for insulation, this board provides stability and drainage for the entire system.
- EPS Continuous Insulation: The insulation layer ensures thermal resistance by minimizing heat transfer and enhancing energy efficiency.
- Base Coat: The base coat is where a heavy mesh is embedded within the system, providing structural reinforcement.
- Reinforcing Mesh: Standard mesh is installed over the base coat and heavy mesh to offer additional strength and support.
- Finish: The final layer not only enhances the appearance of the wall but also adds another level of protection against external elements.
Frequently Asked Questions
Question: Why is it recommended to use heavy mesh in ground floors and high traffic areas?
Answer: The addition of heavy mesh in an EIFS wall assembly boosts its strength and durability, making it more resistant to damage from impacts. This is especially crucial in areas with high foot traffic and on ground floors where the risk of impact is greater.
Question: What does the base coat do in an EIFS wall assembly?
Answer: The base coat is responsible for housing the heavy mesh. It is applied before and after the mesh, securely embedding it into the system and providing an extra layer of protection.
Qnswer: How does an EIFS wall assembly contribute to energy efficiency?
Answer: The EPS continuous insulation layer within an EIFS wall assembly plays a key role in enhancing energy efficiency by reducing heat transfer through thermal resistance.
In conclusion, incorporating heavy mesh into an EIFS wall assembly significantly enhances its durability and strength, making it a suitable choice for high traffic areas and ground floors. By comprehending the functions of each component within the Exterior Insulation and Finish system wall assembly, professionals can ensure optimal performance and longevity of the system.

Project in Pontiac Michigan
Here is a project we completed that we used heavy mesh around the dock bay doors. This area is a high traffic area with many deleivers every day so it made a lot of sense to repair this area using heavy mesh to make it many times stronger then it was to help prevent future damages.
