An improved freezethaw characteristic is achieved in concrete by substituting crumb rubber for entrained air. The apparatus is a thermal management system having a thermal distribution assembly in either one of or both of conductive and radiative communication with heat generating elements. The nano-composite is practically useful in formulating compositions such as rubber and tire products with improved gas permeability, cure properties, andor mechanical properties etc. Once attached, the installed frame provides the required rigidity to the structure. A biasing member is engaged to the sheath assembly and is configured to apply a force thereupon towards the distal housing opening.
