Permanence for wood siding

Creator:: Verrall, A. F. (Arthur Frederic), 1905-2002 and United States. Division of Forest Pathology
Abstract:: Until the last decade, decay in siding did not present a problem. When it occurred it was usually limited to a few boards where there had been some obvious error; for example at points where large amounts of rain water were allowed to run down the wall from leaks in...

Deterioration of fiberboard by molds

Creator:: Englerth, George H. (George Henry), 1907-1991, United States. Division of Forest Pathology, and Forest Products Laboratory (U.S.)
Abstract:: The mold resistance of fiberboard has been studied to provide a basis for recommendations on the relative merits of various types of commercial and of experimental fiberboards. The experimental fiberboards were prepared. by the Division of Pulp and, Paper of the Forest Products Laboratory.

Breaking radius of discolored wood in aircraft veneers

Creator:: Scheffer, Theodore C. (Theodore Comstock), 1904-2003, Duncan, Catherine G. (Catherine Gross), 1908-1968, United States. Division of Forest Pathology, and Forest Products Laboratory (U.S.)
Abstract:: The breaking radii of variously discolored veneers of six different hardwood species were small enough, for most of the discolorations, to indicate that such veneers can be used successfully on members having curved surfaces. When expressed in terms of the minimum radius of curvature attained without fracturing, the breaking radius...

The significance of the discolorations in aircraft lumber : noble fir and western hemlock

Creator:: Englerth, George H. (George Henry), 1907-1991, Hansbrough, J. R. (John Raymond), 1903-1990, United States. Division of Forest Pathology, and Forest Products Laboratory (U.S.)
Abstract:: A survey was made in Oregon and Washington of the discoloration occurring in noble fir and Western hemlock wood, and the present data are presented as an aid in the inspection of these woods for aircraft and other high-grade lumber. Recommendations, based on strength tests of similar discolorations in spruce...

Molds and bacteria that delaminate plywood bonded with casein and soybean glues

Creator:: Christensen, Clyde Martin, 1905-1993, Moses, C. S., United States. Division of Forest Pathology, and Forest Products Laboratory (U.S.)
Abstract:: Wood joints properly made with protein glue should last indefinitely under dry conditions. However, under moist conditions some glues are subject to the actions of micro-organisms and chemical hydrolysis. In previous work the action of bacteria has been discounted as the cause of delimitation of casein glued plywood in the...

The significance of the discolorations in aircraft lumber : Sitka spruce

Creator:: Hansbrough, J. R. (John Raymond), 1903-1990, Englerth, George H. (George Henry), 1907-1991, United States. Division of Forest Pathology, and Forest Products Laboratory (U.S.)
Abstract:: A survey was made of the discolorations occurring in Sitka spruce wood, and toughness tests were made on specimens that included discolorations of unknown or doubtful significance.

The decay resistance of oak wood

Creator:: Scheffer, Theodore C. (Theodore Comstock), 1904-2003, United States. Division of Forest Pathology, and Forest Products Laboratory (U.S.)
Abstract:: Intelligent selection of wood for the job it is to do is particularly essential during wartime conditions of scarcity when supplies must be conserved and useful life extended. One way of increasing the service life of wood exposed to damp conditions is to select material that has a high natural...

Lumber shipped green can be protected against decay

Creator:: Hartley, Carl, 1887-1968, United States. Division of Forest Pathology, and Forest Products Laboratory (U.S.)
Abstract:: No one prefers green lumber. Its higher shipping weight, poorer nail-holding power, and shrinkage after fabrication are well known, but the present pressure for deliveries results in much of it being accepted. Another major objection to lumber shipped green is that is may be damaged bu wood-decaying fungi, either in...

The significance of the discolorations in aircraft veneers : American beech

Creator:: Hansbrough, J. R. (John Raymond), 1903-1990, Waterman, Alma M. (Alma May), 1893-, Krause, R. L. (Robert Louis), 1914-, United States. Division of Forest Pathology, and Forest Products Laboratory (U.S.)
Abstract:: American beech (Fagus grandiflora) is now, and probably will be, increasingly used to replace yellow birch for aircraft construction. Even though it is one of the principal components of the northern hardwood forests of North America, study of the characteristics and properties of its wood has been neglected to the...

Significance of air-dry wood in controlling rot caused by Poria incrassata

Creator:: Scheffer, Theodore C. (Theodore Comstock), 1904-2003, Chidester, Mae Spradling, United States. Division of Forest Pathology, and Forest Products Laboratory (U.S.)
Abstract:: The rat caused by Pozia incrassata (Berk, and Curt.) Burt (sometimes erroneously called "dry rot") in individual cases is the most destructive of the building decays in the warm coastal portions of the United States and the South. The fungus usually attacks rapidly and may cause damage necessitating extensive repairs...

Sapstain control treatments before or after dressing

Creator:: Hartley, Carl, 1887-1968, United States. Division of Forest Pathology, and Forest Products Laboratory (U.S.)
Abstract:: Dipping or spraying green lumber with stain control chemicals has been reported recently as valuable for delaying or preventing stain and decay infection in bulk-piled lumber, as well as in the air-seasoning piles for which such treatments were originally developed. But it should be kept in mind that if lumber...

Decay resistance of heated and unheated mesquite and Utah juniper post wood

Creator:: Scheffer, Theodore C. (Theodore Comstock), 1904-2003 and United States. Division of Forest Pathology
Abstract:: The heartwood of mesquite (Prosopis juliflora var. velutina) and of Utah juniper (Juniperus utahensis) is generally considered to have outstanding decay resistance. Quantitative evidence of the juniper superiority appears in a study of old fence lines by Meagher. Nearly three fourths of the juniper posts averaging 3.6 inches in diameter...
