What is E.I.F.S.?
EIFS is Exterior Insulation and Finishing Systems, also known as Synthetic Stucco. It was first invented by a company called Sto Corp. and introduced to Europe in 1963. During the energy crisis of the 1970s, it was introduced into North America, since EIFS was considered an important cladding for energy conservation. Today, EIFS is the fastest growing residential wall cladding system, surpassing brick in many residential markets as the cladding system of choice.
Why is it so popular?
Few, if any other materials, have such a wide range of benefits such as superior energy efficiency, and an almost unlimited design flexibility. It also has excellent resistance to dirt, mildew and mold. A simple hosing down is all that’s necessary should the surface ever become soiled.
Is it suitable for our climate?
The application of EIFS is like wrapping the exterior of a home in an energy-efficient thermal blanket. By insulating outside the structure EIFS reduces air infiltration by as much as 55% compared to standard brick or wood construction, stabilizes the interior environment and reduces energy consumption. It also adds to the R-value of a home. The R-factor for EIFS is 3.8/inch compared with brick, for example, which is 0.20/inch. When combined with standard wall cavity insulation, this extra layer can boost wall insulation from R-11 to R-16 or more.
