The specialty carbon blacks is uniformly dispersed throughout the foam product and is employed in an amount sufficient to increase both the initial and aged insulation value, i.e., R-value, of the product to above the respective insulation values it would have with the carbon black omitted. Any carbon black which can be uniformly dispersed in the foam at levels of about 1-20, preferably 2 to 10, weight 2%, based on the weight of the polymer in the foam, can be used for improvement of insulation value.
