Bureau of Standards making extensive tests of glass building blocks. Washington, D.C., June 20. Hollow glass building blocks are being used more and more extensively for structural purposes when both greater light distribution and air conditioning are required. Extensive tests to determine the strength of glass block walls and their resistance to wind pressure and moisture penetration. A.N. Finn, Chief of the glass section, is inspecting some 8 x 4 feet panels before they are tested, 6/20/38
