There have been divergent trends in con- 

 sumption of the three major types of building 

 board in recent years (table 37). Insulation 

 board, used largely for residential sheathing, has 

 not shown much change, averaging 2.7 billion 

 square feet per year from 1952 to 1962. In 

 contrast, consumption of hardboard in furniture, 

 fixtures, millwork and cabinets, doors, paneling, 

 siding, advertising displays, lockers, and various 

 other products roughly tripled in the same period. 

 Use of particleboard as core stock in wood veneer 

 and plastic-overlay furniture and such items as 

 panels, fixtures, doors, sheathing, and under- 

 layment also showed a rapid increase from about 

 105 million square feet in 1955 to over 600 million 

 square feet in 1962. 



Since 1947 there has been a fairly close relation- 

 ship between per capita consumption of building 

 boards and per capita gross national product. 

 On the basis of this relationship and the analysis 

 of demands for building board for individual end 

 uses presented in earlier sections, it has been 

 estimated that demands for building board by 

 2000 will be about 3.2 times the level of 1962. 

 Measured in tons, projected demands for insula- 

 tion and hardboard rise from 2.1 million tons in 

 1962 to 6.8 million tons in 2000. Projected per 

 capita use rises from 23 pounds to 42 pounds.

Other board.— The term "other board" includes 

 setup boxboard used in such products as shoe 

 boxes; tube, can and drum stock; liners for gypsum 

 plasterboard; cardboard; wet machine board; and 

 other miscellaneous grades. Consumption of this 

 group of products rose from 2.1 million tons in 

 1950 to 2.5 million tons in 1955— a level that was 

 maintained without substantial change through 

 1962. Per capita consumption also increased in 

 the 1950-55 period from 28 to 30 pounds but sub- 

 sequently declined to 28 pounds in 1962. Pro- 

 jected demands show a slight rise in per capita 

 use to 30 pounds and a total demand of 4.9 million 

 tons by 2000. 



Nearly Nine-Tenths of U.S. Paper and Board 

 Consumption Supplied by Domestic Industry 



In 1962 nearly 90 percent of the paper and board 

 consumed in the United States, or 37.6 miUion 

 tons, was supphed by domestic mills (table 38). 

 Total imports, consisting chiefly of newsprint, 

 totaled about 5.8 million tons and exports about 

 1 million tons. Both imports and exports have 

 increased steadily since 1950, while net imports 

 have shown little change.
