Natco Hollow Tile construction represents a sum of advantages which no one who plans to build can afford 
to overlook. Speed in.construction, enhanced investment value and low maintenance. An important advantage of 
Natco walls is the fact that the interior is insulated against sudden or extreme atmospheric changes by the blanket 
of dead air which completely surrounds it. A Natco house requires materially less heating equipment. 
“Natco Throughout” is a term of fire-safe construction which is sinking deep into the convictions of architects, builders 
and building investors. It means fireproof construction for walls, partitions, floors and roof, and complete security 
against the destruction of your home by fire. The increased cost over partial Natco forms is not of sufficient impor¬ 
tance to weigh against the many advantages gained.
