Fourth Avenue Junior High School – Yuma, Arizona

The building that the Fourth Avenue Junior High resides in was built in 1920 and was named a National Historic Landmark in 1982. When the building required a re-cover roof project, its National Historic Landmark status and student safety was top priority. Due to its history and age, care needed to be taken when completing the project. The products installed were required to be odor-less and could not damage the building. A second requirement for the project was that it be completed quickly and without lingering odors, because they planned to complete the installation over their holiday break. This is where SOPREMA products came into play.
