Hello everyone,
a basement room is to be insulated from the inside.
With the u-value calculation I arrive at:
Under these conditions, no mold growth should be expected.
Feuchteschutz
During the winter condensation period of 90 days, a total of 0.175 kg of condensate water per square meter occurs in this component. This amount dries out within 81 days in the summer (evaporation period according to DIN 4108-3:2014-11).
# Material sd-value Condensate water Drying period Weight
m kg/m² % days kg/m²
1 1.5 cm Knauf Rotband bonding plaster gypsum 0.08 - 0.0 14.3
2 5 cm rigid foam, XPS 4.00 0.15 8.6 1.8
... on outside 0.15
3 1.5 cm lime cement plaster 0.52 0.17 0.6 27.0
... on inside 0.15 70
... on outside 0.023
4 25 cm reinforced concrete (1%) 32.50 0.026 0.0 575.0
... on inside 0.023 81
... on outside 0.0024
5 0.3 cm bitumen thick coating 150.00 - 0.0 3.2
... on inside 0.0024 42
33.3 cm entire component 187.10 0.18 81 621.2
The calculation on the internet says: "No mold is to be expected."
However, condensation water does occur after all, and that makes me uncertain now.
Is it okay as it is done as described above?
I don’t want to have to tear everything down again...
