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

Hello 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!

The surface of the top slab is not waterproof. Moisture and rapid temperature changes cause stress.

Preventive measures: Avoid placing wet objects, direct sunlight, or heating sources near the slab.

If you experience large 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

Additionally, small protective caps on the edges or installing edge protection can sometimes help. This reduces splintering at the corners.
