A Warmer House on Less Fuel 
Are you thinking about ways of making 
your house more comfortable this coming 
winter, and cutting down the fuel bills, too? 
Then it will pay you to think seriously 
about Sheetrock, the fireproof wallboard. 
Sheetrock the attic. Sheetrock the base¬ 
ment. Enclose the furnace in a room walled 
and ceiled with Sheetrock. 
At low cost, with little effort and with practi¬ 
cally no inconvenience, you can thus seal 
your house against winter’s draughts and 
cold, keep your heat in, and hold down 
your fuel bills. 
For Sheetrock is a great insulator. It is 
gypsum cast in sheets. It makes solid, tight- 
iointed, permanent and fireproof walls and 
ceilings. It comes in broad, high sheets, all 
ready for use. You nail it to the joists or 
studding, and the job is done. 
Sold by your dealer in lumber or builders’
