Additional Details

Essentia Health opened its doors to the new St. Mary’s Medical Center in Duluth, Minnesota. The hospital aimed to become more efficient and redefine its patient experience with bold, innovative, and sustainable solutions. The striking new building overlooks Lake Superior with a design that is meant to draw from the neighboring town and elements of the lake. As a sign of progressive redevelopment, the hospital will help to financially stimulate the downtown Superior Street area, an underutilized commercial and entertainment hub of Duluth.


Prominent features include amenity deck space on multiple levels, accessible plazas, and rooftop gardens with amazing views of the city and the Great Lake. With the harsh elements of the area a Protect Membrane Roof Assembly was the obvious choice to bring these design elements to life. Monolithic Membrane 6125® will keep the building watertight for the life of the structure and over 10,000 square feet of the Garden Roof® Assembly and 12,500 square feet of the Ultimate Assembly® offer patients, healthcare workers, and visitors a place to gather or take a break.
