All glass buildingIn 1936, the first, all glass, windowless building in the U.S. was completed in Toledo, Ohio as the home of the Owens-Illinois Glass Company Laboratory. It was built using 80,000 translucent water-clear hollow glass blocks, weighing about 150 tons. The two stories contained 39 rooms with an aggregate floor area of about 20,000 sq.ft. The glass blocks which were manufactured at the company's plant in Muncie, Indiana, were a structural part of the building. |
