Solid wood Kitchen Cabinets are made of wood. The moisture of the wood that has just been saw accounts for 40% of the weight. After drying the board, it retains an appropriate amount of moisture to coordinate with the relative humidity of the natural environment before it is made into Kitchen Cabinets. Kitchen Cabinets' wood will continue to exchange moisture with air and shrink and expand as the relative humidity changes.
Solid wood panels are like human skin. When the air is extremely dry, they lose water and shrink. The surface of the solid wood may have a few cracks, but when the relative humidity increases, the solid wood will absorb enough moisture to expand slightly. To restore the original condition. Therefore, when the air humidity is too low, Kitchen Cabinets will slightly crack.
