ᐅ Kallax deck board splinters with temperature changes – is this normal?

kizarHello community,
I have an issue with my Kallax shelf top that is quite confusing: during rapid temperature changes (for example, when I get up in the morning in a cool room and turn up the heating, or when I open the windows causing the temperature to quickly rise or fall), the shelf top starts to chip at the edges. The edges show small cracks and flaking, as if the material is "working" or warping.
Now I’m wondering: is this normal behavior for the Kallax shelf top or the materials used? Or could it be a manufacturing defect or a general quality issue?
I couldn’t find any official information from IKEA or in other forums that really explain this phenomenon. By the way, the shelf top is original, not a cut-to-size version or anything like that.
Does anyone here have experience with the temperature sensitivity of Kallax panels? Or any tips on how to prevent this? I would appreciate any advice!

Splitting due to temperature changes is not normal.That's right, it does sound really frustrating. My Kallax panels never did that, even though our evenings sometimes get quite chilly. Maybe maintaining a more stable temperature or using moisture protection could help. 🙂
Regarding the cause: The Kallax top panel is made of MDF with a melamine coating. MDF is generally sensitive to fluctuations in humidity and temperature changes, which can cause warping or minor cracks.
However, chipping on the surface is unusual, as melamine usually provides protection against such effects.
It is possible that either the coating was damaged or the material is defective. Transport or installation conditions involving moisture and temperature issues can also be a factor.
My tip: Check if the ambient humidity varies significantly and whether the panel is exposed to direct water vapor or drafts.

The edges show small cracks and chipping, as if the material is “moving”Although the Kallax usage concept is designed for sturdy furniture, the top panels are not classified as particularly temperature- or moisture-resistant surfaces.
I would generally question whether the material itself has a structural weakness here or if external conditions (e.g., strong drafts combined with heat) are contributing to this damage.
Also: Was there any prior mechanical stress on the edges? Chipping can also indicate microscopic microdefects in the material that worsen due to temperature changes.
Hello kizar,
I would like to add that Kallax furniture is made from medium-density fiberboard (MDF) panels, which are coated with decorative foil or melamine resin. These panels are generally not designed for extreme temperature fluctuations or high humidity.
If you experience rapid temperature changes within a short period (e.g., from 15°C (59°F) to 25°C (77°F) and back), the material can expand and contract, causing stress at the edges. This might explain the cracking.
A tip: Try to keep the temperature as stable as possible and avoid drafts. Additionally, using a protective mat or cloth on the surface can help cushion the transition temporarily.
If the damage continues to spread, it might be worthwhile to replace the top panel and consider using more durable materials for everyday use.
