ᐅ IKEA Kallax next to a window – Problems with condensation?

Hello everyone,

I am currently considering placing my new IKEA Kallax shelving unit right next to the large window in the living room. However, I have concerns about potential issues with condensation. The windows are double-glazed, but on colder days, dew often forms on the glass, especially in the mornings. Now I am wondering if having a piece of furniture directly against the cold surface increases the risk of higher moisture levels between the window and the shelving unit, possibly leading to mold or moisture damage.

Does anyone have experience with this problem when placing a Kallax unit directly next to a window? Are there any observations on whether the furniture traps moisture at the window or affects air circulation? What measures could help if you still want to put the shelving there?

I would greatly appreciate detailed answers, including tips on moisture, air circulation, insulation, or similar factors I should consider.

Humidity during the cold months is usually between 50 and 60%, but it has briefly been measured above 65%.

These are definitely relevant values regarding condensation issues. Therefore, I recommend the following approach to optimize the location of the Kallax shelf:

First, try not to place the furniture directly against the windowpane; maintaining at least a 5 cm (2 inch) gap is important. This allows for a minimal air gap that encourages air circulation and helps reduce moisture buildup.

Regarding humidity: if you cannot keep it consistently below 60%, there is indeed an increased risk of condensation forming on colder surfaces in the room.

As a long-term solution, using a dehumidifier is advisable if the indoor climate cannot be improved through regular ventilation, proper heating, and air exchange. It is important to remove only as much moisture as needed to avoid creating an excessively dry indoor environment.

In addition, please check whether the window is properly sealed and preventing moisture from entering from outside. Sometimes the main issue is caused by leaks.

If possible, monitor the humidity levels over several days using a hygrometer. This will help identify the best location for the shelf.
