Hello everyone,
we are building a single-family house with a gable roof. The house will be brick-faced. Our energy consultant has created two options for a KfW55 house.
Option 1) Thermal bridge flat rate 0.05, exterior wall insulation 18 cm WLG 032, roof insulation 28 cm WLG 032
Option 2) Thermal bridge flat rate with calculation, exterior wall insulation 18 cm WLG 035, roof insulation 24 cm WLG 035
Is it due to the calculation of the thermal bridge flat rate that in option 2 insulation can be done with a lower thickness and a worse WLG, or is there a typo?
Thanks and best regards Fabian
