How it is calculated

How this wall build-up is calculated

R = d / lambda

Each layer adds resistance using R = d / lambda. The final U-value includes the wall leaf, the insulation, and the surface resistances.

U = 1 / (Rsi + sum(R layers) + Rse)

This page is a quick reference, while the main calculator remains the place to adjust the exact project layers.
