Apparent Thermal Conductivity Versus Density as a Function of Blown Thickness for Pneumatically Applied Insulations: Continuing Studies


Seventy-three samples of pneumatically applied mineral fiber insulations were tested in a heat flow meter apparatus. The measured value of apparent thermal conductivity for these materials seems to be influenced negatively by the percentage of compression beyond the blown test sample thickness. The magnitude of this “compression effect” does not seem to be constant across the product and density spectrum. Implications for product evaluation and further test standardization are discussed.
