During the past 10 years there has been a housing boom for which we may never see again. Part of this increased demand for housing has lead architects and builders to find new ways of cladding the exterior of homes. Unfortunately, one of the products used was Exterior Insulation Finish Systems (EIFS). EIFS is a non-load bearing exterior wall cladding designed to be attached to wall sheathing with an adhesive or mechanical fastener. The system typically used in residential construction is categorized as non-drainable or barrier type system. The system consists of four components: 1. Panels of expanded polystyrene foam insulation glued, screwed, or nailed to the substrate. 2. A base coat that is troweled over the foam insulation panels. 3. A glass fiber reinforcing mesh that is laid over the polystyrene insulation panels and fully embedded in the base coat. 4. A finish coat that is troweled over the base coat and the reinforcing mesh. EIFS Problems
The inherent problem with the system is that once water penetrates the surface of the cladding, the system has no way of weeping or letting the water return to the exterior of the house. Without a mechanism for allowing the water to return to the exterior of the house, the water remains in contact with the sheathing and structural members of the house and eventually will cause rotting due to excessive moisture levels. Weeks Engineering Construction & Consulting, LLC structural engineers can provide solutions for EIFS clad houses. These may include damage assessment reports, maintenance guidelines, and removal of EIFS. We are fully insured with Workman's Compensation Insurance and General Liability Insurance. EIFS ContractorQ.
