Blown cellulose fiber thermal insulations. Part 1. Density of cellulose fiber thermal insulation in horizontal applications
Results are presented of a study to determine the effects of transport and placement conditions on the initial density of the insulation; establish a standardized method for producing specimens of blown cellulose fiber insulations; investigate the factors that cause the material to settle after placement; and establish a standardized method to produce settlement in the specimens comparable with those found in field studies. A method recommended for producing settlement in the specimens consists of two procedures, one simulating settlement by impact produced on the standardized containers, and the other causing settlement under climatic cycling of the material.
