Clay r value
WebOct 17, 2024 · An insulating material’s resistance to conductive heat flow is measured or rated in terms of its thermal r esistance, or R-value (defined as ft²·°F·hr/BTU; or square feet · degrees Fahrenheit · hour/BTU; or area · temperature difference · time/heat loss). The higher the R-value, the better a material performs as a thermal insulator. WebThat is, ordinary concrete has an R-value of 0.08 - 0.3125 per inch, depending on various sources and variations in concrete mix. Using the first data point of R 2.5 for an 8-inch thick wall, that's the high end of the R …
