In 1969, Dryvit Systems, Inc. introduced North America to an exterior wall cladding system based on a revolutionary concept: installing insulation as part of the outside wall. Since that time, Dryvit's innovative systems have been used successfully on hundreds of thousands of commercial and residential buildings. Today, the West Warwick, Rhode Island based company remains North America's leading EIFS manufacturer with an ever-growing line of diversified products. Whether you're building a new structure or renovating an older one, a Dryvit system is cost effective to install and thermally efficient. In fact, it's the most thermally efficient wall system available today. Dryvit, which is owned by RPM International Inc. in Medina, OH operates four manufacturing plants in the U.S., including one at its headquarters in West Warwick, RI, and has subsidiary operations in Canada, Poland and China.
