One. Are wood panels susceptible to sun damage?
Afraid.
Although the moisture content of wood panels is relatively low, ranging from 10% to 13%, this does not mean that wood panels do not contain moisture.

Any moisture-containing wood is susceptible to sun damage. When wood is exposed to direct sunlight, the moisture within the wood continuously evaporates. Initially, the wood loses its free water, which is the change in moisture content above the fiber saturation point, without affecting the wood's properties. As the sun exposure continues, the free water is completely lost, and the moisture content drops below the fiber saturation point, causing the wood to start shrinking and cracking. Further reduction in moisture content leads to continued shrinkage, resulting in cracking and deformation.
Two. What will happen to wood planks that are exposed to sunlight for a long time?
1、Cracking or deformation
Long-term exposure to sunlight, increased temperature inside the wood, and the evaporation of moisture can cause the wood to crack due to differential shrinkage rates between different areas.
2、Discoloration or fading
Wood exposed to direct sunlight will typically maintain its natural wood color or a color close to wood, which helps prevent fading. However, wood with brighter colors is more prone to fading.
