Detailed explanation-1: -The R-value refers to the ability of insulation material to resist heat flow. This term is mostly used as commercial identification when buying insulation materials. R-values can vary depending on the heat flow direction through the product. Insulation with higher R-value is better for thermal performance.
Detailed explanation-2: -To find the average heat loss per unit area, simply divide the temperature difference by the R-value for the layer. If the interior of a home is at 20 °C and the roof cavity is at 10 °C then the temperature difference is 10 °C (or 10 K).
Detailed explanation-3: -Insulation means creating a barrier between the hot and the cold object that reduces heat transfer by either reflecting thermal radiation or decreasing thermal conduction and convection from one object to the other. Depending on the material of the barrier, the insulation will be more or less effective.
