🧱 Identify each material layer in the wallLook up each layer's R-valueAdd layers in series: R_total = R1 + R2 + R3Know area A and ΔT?🔥 Compute Q/t = A·ΔT / R_totalMeasure or specify A and ΔT first✅ Compare to code minimum or targetMeets target?Add or upgrade a layer, recompute❄️ Design acceptedYesNoNoYes
