Concrete R-Values The insulating capability of a given material is indicated with a number called an R-value; the higher the R-value of a material, the more resistant it is to the transfer of heat from one side of the material to the other.
An R-value is a unit of thermal resistance for a particular material or assembly of materials (such as an insulation panel).The R-value depends on a solid material's resistance to conductive heat transfer.In other words, compressing a fiberglass batt decreases the R-value of the batt but increases the R-value per inch.) Another important factor to consider is that studs and windows provide a parallel heat conduction path that is unaffected by the insulation's R-value.
