Abstract

There has been constructed a thermal conductivity apparatus of the guarded hot plate type employing a compensatory heating unit and designed to test samples having low values of thermal conductivity. Tests on various types of loose-fill thermal insula· tors reveal that there is a linear increase of thermal conductivity with increased moisture content. Depending upon the particular type of sample under consideration, a hygroscopicity of 20 to 30 per cent by weight completely vitiates the efficacy of loose-fill jnsulation.
