WebThermaflow™ Thermal Fill Thermaflow is a range of thermally conductive concrete mixes that both conduct and transfer the considerable heat generated by buried electric cables. Its performance is pre-tested and third party verified for … WebA Fluidized Thermal Backfill™ (FTB™) can be poured in place. It has a dry resistivity of around 0.75 m C/W, decreasing to below 0.5 m C/W when wet. Measurement. While it is possible to compute thermal properties of soil from physical properties, it is usually easier to measure them directly than to do the computations.
