Beauty of 
Look at a wall of Sheetrock. 
That smooth and flat expanse invites good decora¬ 
tion. It forms an accurate, firm and perfect base for 
wallpaper, paint or panels. 
You may be sure, too, that it will be just as solid 
and just as flat many years from now, because it is 
made of Sheetrock, and Sheetrock is rigid, will not 
buckle , shrink or warp. 
Every part of it is tight-jointed, vermin-proof and 
sound-proof, because Sheetrock is made with the 
patented U. S. G. edge, for extra nailing strength 
and perfect union. Where panels are not employed, 
Sheetrock Finisher seals the seams completely. 
Moreover, walls and ceilings of Sheetrock are fire¬ 
proof. Sheetrock is gypsum plaster cast in sheets. 
It will not burn, ignite, or transmit heat. It keeps 
buildings cooler in summer, warmer in winter. 
Sheetrock comes in broad, ceiling-high sheets, all 
ready for use. The carpenter nails it up, quickly, 
easily and cleanly. Your dealer in lumber or builders’ 
supplies sells Sheetrock. Write for a sample and for

ing the fine effects that are possible with Sheetrock.
