Good evening everyone,
today I worked a lot in the attic, and the humidity there has risen to 96% rel. at 5°C. The attic is not insulated, meaning the insulation is between the upper floor and the attic. No moisture comes in, everything is well sealed, including the stairs. The roof is also tight.
The problem now in the cold days is that warm air from the living space above condenses and thus the relative humidity there increases when I have the hatch open for a longer time.
I have a wireless thermo/hygrometer there. Currently it has dropped to 4.0° and 92%.
From which value does it become critical here? Do dehumidifiers help, especially with the cold air?
Best regards Tobias
