Abstract
Measurements were made of the effects of moisture upon the heat flow in simple cases of transient heat flow established under control in laboratory apparatus. Samples of various materials, but mainly of the building insulation type, 7 in. square and up to 2 in. thick were enclosed in a special cell, between hollow plates through which liquid was circulated for heating or cooling. Variation of heat flow with time is shown for various amounts of moisture present and compared to both the experimental and calculated transient conditions for dry materials. Very substantial modifications to the heat flow under transient conditions result from the presence of moisture.
