FAQ

EIFS is also known as the exterior insulation and finish system. It is a multi-layered construction material used to provide insulation and a decorative finish to the exterior of buildings. The installation process typically involves the following steps:
1. Preparation. The existing wall surface is cleaned and prepared for EIFS installation, including the removal of any debris, old coatings, or damaged materials.
2. Insulation Board Installation. A layer of rigid insulation boards is affixed to the exterior wall using adhesive or mechanical fasteners. This helps improve the building’s energy efficiency.
3. Base Coat Application. A base coat, which is a cementitious mixture, is applied over the insulation boards. It serves as a protective layer and provides a smooth surface for the finish coat.
4. Mesh Reinforcement. A fiberglass mesh is embedded in the wet base coat to enhance the system’s strength and durability.
5. Finish Coat Application. The final layer, known as the finish coat, is applied. This layer is available in a variety of colors and textures, giving EIFS its aesthetic appeal.
6. Detailing and Finishing. The edges and corners are detailed, and any architectural features are incorporated into the system. This step ensures a seamless and attractive appearance.
7. Curing and Maintenance. The EIFS system is allowed to cure, and regular maintenance is recommended to preserve its appearance and performance.
EIFS installation should be carried out by trained professionals to ensure a successful and long-lasting application.
EIFS offers an exterior finish akin to traditional stucco or textured plaster. It added the benefits of insulation, design versatility, and lighter weight. Also, it can replicate various textures. For example, stucco, stone, or brick, while improving energy efficiency.
