Eifs Siding Problems

To compensate for this the mesh is coated with plastic and the alkaline environment is buffered chemically.

Eifs siding problems.

Inappropriate sealant may even lead to cohesive failure of the eifs finish coat. Sealant joints are a major source of problems with eifs cladding. Damage can be repaired but not easily. That s fine when no moisture is present behind the covering but moisture can become trapped behind the layers if it seeps in.

But eifs houses were still the focal point. Incorrect selection or application of sealants or missing sealants provides an easy path for water entry and premature deterioration. Windows doors electrical outlets roof flashings deck flashings below grade installation. What are the problems with eifs.

In march of 1999 the nahb national association of home builders research center listed the most common problems they found that were associated with water intrusion in eif systems as being. The problems with barrier eifs cladding all stem from water intrusion. The longer water penetrates the building envelope the greater the potential damage. Major eifs problems with water trapping have caused rot and decay of homes using this product.

The components principally affected are the interior and exterior gypsum sheathing the metal or wood studs and the fiberglass cavity insulation. Before the eifs industry knew what had happened the news media was reporting building defects in these eifs houses. Eifs is usually sprayed onto mesh that is mounted to styrofoam type of material. While the focus was on eifs clad houses it would soon be learned that the water intrusion problem occurred in all houses regardless of the cladding.

Constant exposure to moisture can lead to dry rot in wood when moisture has no place to go. The eifs layers bond together to form a covering that doesn t breathe. This mechanism of deterioration. Moisture accumulation in the wall cavity.

Eifs are vulnerable to damage due to the combination of a thin stucco coating over a soft base make. 85 of all remediation costs less than 1500 and is usually a maintenance issue. Impacts to the surface can result in cracks. However prolonged exposure of the lamina to moisture eventually leads to a loss of strength of the fiberglass mesh.

Using the soft styrofoam substrate allows the builder to use less of cement stucco material. Why eifs problems occur. These problems include moisture accumulation in the wall cavity subsequent wood damage and in more advanced cases mold growth and the infestation of pests such as carpenter ants or termites.
