Although Eifs coating systems have been around for decades, the methods continue to improve. Originally developed in Europe,  EIFS, Exterior Insulation and Finish Systems, has evolved into a perfect insulating, moisture resistant, and durable cladding for any structure.

An important supplier-partner of ProCoat Systems of Denver is STO Corp, the global leader in Continuous Insulation Systems. These companies provide EIFS component materials including air and moisture barriers, backup wall systems, and StoTherm® ci continuous insulation systems to enhance energy efficiency.

The key to EIFS  construction is the sequencing of several layers of different materials strategically incorporated in a specific order. Each layer has a definite purpose that includes resisting energy loss, inhibiting and carrying away moisture, and adding strength and durability to the wall. The exterior layer is a specially designed acrylic stucco-like finish.

EIFS is a non-load bearing wall structure designed to reduce energy loss for commercial and residential structures.

Layers of EIFS

From the inside out, a finished EIFS layering system consists of a reinforcing mesh and an inner gypsum board layer attached with an adhesive to a plywood substrate of the building wall. Adhesives should be used instead of metal fasteners at each step since metal is an efficient energy conductor.

• A reinforcing mesh is applied to the substrate.
• Drainage plane to eliminate moisture that may penetrate to this level is next.The gap is created by applying house wrap, felt, or trowel application.
• An insulation board is placed securely over the reinforcing mesh. The thickness of the insulation board can vary from ¾” to 4-inches depending upon the degree of energy retention desired.
• A prescribed base coat is applied over the insulation board to act as a moisture barrier. This material provides the outer moisture barrier to the system.
• Press mesh material into the base coat so that it is invisible within the base coat material. Once the base coat and mesh have dried, a primer coat may be added to increase protection.
• A durable, acrylic-based, crack resistant exterior coating is applied. While the finished exterior layer has the appearance of stucco, it is designed to last longer, be moisture resistant while providing a beautiful and classic outer appearance.
