Located on the fringes of Acadia National Park, Ellsworth Elementary School is the first significant green roof in northern Maine. The green roof here is as bare bones as it gets. The underlying components consist of Zinco fabrics and drainage board with 4” of soil above and topped with sedum cuttings. Due to the protected nature of the building, wind protection was not necessary.
