THE OUTLOOK FOR TIMBER DEMANDS 



27 



Of the lumber used in nonresidential repairs 

 more than three-fourths was for framing, sheath- 

 ing, and siding. Millwork items made up about 

 9 percent of this total, concrete forms and other 

 facilitating uses about 4 percent, and paneling and 

 flooring about 1 percent. 



Projected Lumber Consumption Shows 

 Substantial Rise by 2000 



Lumber consumption for upkeep and improve- 

 ments in 1962 was estimated at about 0.394 board 

 foot per dollar of expenditure for residential 

 properties and 0.080 board foot for nonresidential 

 (table 15 and fig. 13). Declines in lumber use

per dollar of expenditure are expected — to an 

 estimated 0.240 board foot for residential and 0.050 

 board foot for nonresidential properties by 2000 — 

 in response to continuing changes in use of mate- 

 rials and types of construction and the general 

 decrease in the use of all materials per dollar of 

 construction expenditure. 



This projected drop in wood-use factors is more 

 than offset, however, by projected increases in 

 total expenditures. As a consequence, estimates 

 of total lumber use rise from 5.4 billion board feet 

 in 1962 to 7.8 billion board feet in 2000 (fig. 13). 

 This includes an estimated 6.4 billion board feet 

 for residential upkeep and improvements and 1.4 

 billion board feet for nonresidential repairs. 



7.5 Billion Square Feet of Plywood 

 Used in 1962 — Projections Show Rise 

 to 3.8 Billion Square Feet in 2000 



The volume of plywood used for upkeep and 

 improvements of residential and nonresidential 

 structures totaled approximately 1.5 billion square 

 feet (%-inch basis) in 1962 (table 16 and fig. 13). 



An estimated two-thirds of the total plywood 

 used went into residential repairs, alterations, and 

 additions — mainly for sheathing, siding, partitions,
