YOUR NEW HOME 
can and should be 
a stronghold of fire- 
safety. Fortify it against 
interior and exterior 
fire disasters by speci¬ 
fying and building of 
Fireproof, damp-proof, vermin-proof, age-proof; Warmer in Winter, cooler in Summer 
Besides the element of fire immunity established by the use of “Natco” for walls, partitions, floors 
and roof, are the compelling factors of rapidity and economy of construction, permanence and 
low maintenance. 
A “Natco” house is shielded against extreme heat or cold by the blankets of still air which com¬ 
pletely surround and insulate it. 
“Natco” for your outer walls alone provides a form of construction vastly superior in every way 
to any of the older materials singly or combined. And, the cost is but little more. 
The word “Natco” stamped into each block guarantees to all structures of moderate size the 
skyscraper standard of general structural efficiency. Natco Hollow Tile is the same material (and 
the same Company’s product) as used in the fireproofing of the country’s most gigantic and 
notable business and public edifices. Inferior substitutes will be avoided by specifying “Natco” 
by name and being sure that you get it.

“Natco” construction. Contains 80 photographs of “Natco” buildings. Mailed anywhere for 20 cents to cover postage. Write for it today.
