WebFeb 27, 2024 · In construction, the R-value is the measurement of a material's capacity to resist heat flow from one side to the other. In simple terms, R-values measure the effectiveness of insulation and a higher number represents more effective insulation. R-values are additive. WebBuilding regulations determine the maximum allowed U-value: Walls: 0.27 Floor: 0.22 Roof: 0.16 Windows and doors:1.80W/m²K.
