Garden door behind sofa & condensation/damp

andre_xs

Hi,
we have to arrange our living room in a way that the sofa blocks the glass door into the garden (access only through kitchen). It's an old door, aluminium frame with double glazing. Now in the colder season, there's not much ventilation behind the sofa. Thus, in the morning the glass behind the sofa is all foggy, up to the extend that drips of condensation water run down to the bottom of the window/carpet. That, of course, causes dampness and (last winter) even mould, incl the carpet.

Last winter, as a quick fix, I put a small USB fan behind the sofa, coupled with a timer, so that it would run through the night for 15 min once per hour. Condensation in the morning was much lower, but I was wondering whether there is a better solution to tackle the problem?

For instance, would it be possible/feasible to kind of cover the lower part of the window with some insulation material? This area doesn't contribute to lightening the room. However, we would still need to be able to open the door (sliding door) for getting fresh air...

Many thanks,
Andre

What are the humidity levels like in the room? Old windows will inevitably get some condensation, even if you do all you can to keep humidity as low as possible as they will simply drop in temperature below the dew point, but the lower you can keep humidity the better. If its too high consider a dehumidifier. Move the sofa away from the window so you can get some more airflow behind there.
