Abstract

An evaluation of scattering and absorbing abilities of light heat insulating materials in the IR spectrum range is given. The generalized form of Fourier equation application to such materials with taking into account radiant environment heat conduction is shown. Convectionless measurements of material specimen thermal resistance of different thickness are performed. Theoretical substantiations and ideas concerning heatprotective material properties are reliably confirmed. Exact values of total material heat conduction are obtained, and values of material radiant heat conduction, as well as of thermal radiation penetration depth into them are estimated.
