R-value insulation - Wikipedia

In the context of building and construction the R-value is a measure of how well a two-dimensional barrier such as a layer of insulation a window or a complete wall or ceiling resists the conductive flow of heat. R-value is the temperature difference per unit of heat flux needed to sustain one unit of heat flux between the warmer surface and colder surface of a barrier under steady-state
