Thickness

The thermal resistance (R value) varies with the thickness and is calculated by dividing the thickness of the individual component (expressed in metres) by its thermal conductivity.

Additionally, an allowance of the calculated resistance is made to compensate for saturated roofs during long periods of rain in accordance with BS EN ISO 6946: 1997 and BRE report (BR443 2006). Conventions for U-value calculations.
