Here is a Different Wallboard 
I F we could place a sample of Sheetrock in your 
hands, you would instantly see and be sure of the 
advantages of this different wallboard. You would see 
Sheetrock just as it is—plaster cast in sections. You 
would measure between your thumb and forefinger its 
3^-inch thickness of pure gypsum. You would run 
your fingertips over its even surface. You would try 
its rigidity, and note how flexible it is along with this 
rocklike strength. And you would probably put it to 
the practical tests of nailing, sawing, and trial by fire.
