Hello everyone,
I recently purchased a new Billy bookcase and noticed that the color of the newer models changes noticeably faster than with older ones. My question is: why does the color of newer Billy models change more quickly?
I observed that especially with the newer shelves, the surface often darkens or discolors unevenly after just a few months. This seems to be less pronounced in the previous model I bought several years ago.
From a technical perspective, what factors cause this? Is it due to the type of coating used, the wood material, the base substances, or perhaps the manufacturing process? I would appreciate detailed explanations, as I would like to understand this better.

Newer panels are often produced more cost-effectively, which means higher porosity and therefore more impact on color absorption and changes.Exactly. Higher porosity also means moisture can penetrate the material more easily – this promotes discoloration.

Thanks for the information so far!
To add: Can the type of coating (e.g., PU varnish vs. melamine resin finish) affect color stability? I’m asking because I noticed that some newer models are described as melamine-coated, while others are varnished.
What difference does this make?

PU varnishes are generally more resistant to mechanical wear and UV radiation, maintaining color better. Melamine resin coatings are less flexible and can fade or yellow more quickly because they are thinner.
The lower application weight of melamine coatings results in a thinner protective layer, which makes the color tone more susceptible to change.
