EIFS Commercial vs Residential
Commercial and Residential applications are two different animals – EIFS Commercial vs Residential
Applying EIFS to a Commercial building is totally different than applying EIFS to a house. One of the big differences between a building, and a house, when it comes to applying EIFS, is the roof. The roof of a house is completely different from a building. A residential roof line is much more complicated than a flat roof of a typical building. It is common for a roof to terminate right into the side of a wall, which creates a problem for water drainage. Normally the water from the roof runs down the flashing and off the roof into the gutter. This is a good system, until a layer of 1 1/2″ foam is applied to the substrate (OSB) of the house. With the EIFS on the house the water runs down the flashing, and right behind the foam creating major issues. This problem is cured by installing a kick out flashing, which kicks the water past the EIFS, and into the gutter. The roof is probably the most obvious difference, but also the windows and doors are different. Another major difference from a commercial project to a residential project it the contractor. Large corporations build commercial buildings and have a team of architects and engineers that spec and design the project, where as, in a residential project this is usually done on a much smaller scale. Residential projects are open to design, and construction short comings due to the lack of specific industry expertise. This issue travels down to the applicator as well. A large commercial builder has a host of EIFS applicators to choose from that have proven track records, where a local residential builder may not see EIFS often and do not have the access to quality applicators.
Make sure when you hire a contractor to build your EIFS home that they have a proven track record of building and designing with EIFS, and that the applicators that he uses are certified.
