Put simply, the R-value is the insulating capability of a given material. The higher the R-value, the more resistant it is to the transfer of heat from one side to the other. Conversely, the U-value is the thermal transmittance capability of a given material. The higher the U-value, the easier it is for heat to transfer from … Ver mais The equation for calculating R-value can be condensed to R = t/?, where ‘t’ is the thickness of the material in metres and ? is its thermal conductivity (sometimes written as the k-value). The … Ver mais If the R-value of your floor or walls is not very high, you may need to resort to alternative methods to reduce heat loss. One method is to insulate the interior of your wall by installing rigid foam board insulation. These … Ver mais Web25 de mar. de 2008 · The thermal resistivity (R-value)will depend on the density of the concrete AND the chemical composition of the aggregates. Generally, lighter concrete has greater resistivity (insulation) than heavier concrete. I don't have a specific reference handy, but normal weight concrete is in the range of 0.06 to 0.11 hr*sf*degree F/BTU/in … orang herodian
