The Dryvit System
Dryvit is one of the largest EIFS manufacturers in the world and they did an excellent job of marketing the EIFS product. In fact they did such a good job that the entire industry was know as Dryvit until recent years. Dryvit did much like Rollerblade® did with inline skates. We now, for the most part, refer to the industry as the EIFS industry, and there are a few manufacturers of the EIFS product, Dryvit being one of them. Each manufacturer of EIFS has there own terminology of the products, so it is a good idea to familiarize yourself with the basic Dryvit lingo.
Lets first look at the materials that are used in a typical EIFS project.
