What Is High R Value Insulation?
Thermal insulation is an important feature of any home or business. Apart from drastically reducing heating and cooling costs, it provides a comfortable uniformity in temperature throughout a structure. Different types of insulation have different levels of efficiency when it comes to blocking heat transfer. This efficiency is expressed as the R value of the insulation. High R value insulation is that which blocks heat transfer relatively efficiently, compared to other types of insulation. The R value is a measure of how well an insulation slows down or blocks heat transfer under specific laboratory conditions. World-wide, the mathematical definition of R value is kelvin square meters per watt. By this calculation, the R value of most insulations is between zero and one. In the United States, R value is measured with degrees Fahrenheit rather than the kelvin scale. This will usually result in a small whole number for an R value. In general, increasing the thickness of an insulating lay
