NettetThe thermal resistance rating or R-Value is the measure used most commonly in the building and construction industry to determine a material’s ability to resist the transfer of heat. The higher the R-Value the better thermal resistance the product will provide. Units: m 2 K/W. R-Value = Thickness (m) / Thermal conductivity (W/mK) Nettetλ is the thermal conductivity in W/mK. The R-value is measured in metres squared Kelvin per Watt (m 2 K/W) For example the thermal resistance of 220mm of solid brick wall (with thermal conductivity λ=1.2W/mK) is 0.18 m 2 K/W. If you were to insulate a solid brick wall, you simply find the R-value of the insulation and then add the two together.
NettetWhat is Insulation R-Value? Insulation ratings are measured in R-values per inch of thickness. An R-value tells you how well a type of insulation can keep heat from … NettetR-value measures how well certain building insulation materials, such as foam insulation, can resist heat. The higher the R-value, the greater the performance of the insulation. Keep in mind that if insulation is compressed, the R-value will decrease. Which R-Value is Right For Your Home?
