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 one … Se mer 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).
