The John G. Shedd Aquarium uses an environmentally friendly soybean-based membrane on its roof system

The aquatic animals that fill the tanks at John G. Shedd Aquarium in Chicago may have thought something fishy was going on during the past year. Helicopters frequently flew around the building at the crack of dawn, and a big deal was being made about the roof.

And with good reason. This was no ordinary roofing project. The aquarium's new roof system was surfaced with a soybean-based ELMS,® or Environmental Liquid Membrane System, which was manufactured by Green Products LLC, Romeoville, Ill., and installed by NRCA member Preservation Services Inc., Romeoville, Ill.

The amount of ELMS applied to the roof system was equivalent to oil taken from 37 acres of soybeans.
