Abstract
For years the heat insulating properties of certain types of metallic coatings have been recognized by engineers and applied in the construction field, a well known ex ample being the use of aluminum paint as a coating for gasoline storage tanks. However, the application of heat reflecting coatings to textiles for the purpose of in sulating against the inflow of cold or the escape of heat from within is a comparatively recent development.
The following digest of an article* by Professor Kirkpatrick gives some of the results of his laboratory tests in which the experimental evidence indicates that a reflective film of negligible weight will compare favorably with conventional textiles in restricting heat loss, and that by proper construction it should be possible to in crease the warmth and at the same time decrease the weight of articles of clothing, blankets, bedding and the like.
