R-Value Table • 38 Types of Insulation and Roofing •

R-value is used in the United States. RSI (R-value Système International ) is the metric equivalent. To convert the R-value of a specific thickness of a material to RSI, divide the R-Value by 5.67826. To convert RSI to R-value, multiply the RSI by 5.67826. For example, two inches of extruded polystyrene, with an R-value of 11, has an RSI of 1

What is R (or RSI) value of insulation? Better Homes BC

The two thermal resistance values you’ll encounter are the RSI and R-Value. The R-Value is an imperial system unit of measurement (ft 2 ·°F·h/BTU) and the RSI Value is a metric system unit of measurement (m 2 ·K/W). The higher the resistance value, the slower the rate of heat transfer through the insulating material. Spray foam, blown-in
