No, after the curing period, the moisture content of the wooden window is relatively stable, and it has a certain ability to resist deformation and cracking. The expansion and cracking of wood mainly depend on the moisture content of wood. When the moisture content of wood is higher than the humidity range, wood will absorb moisture to prevent the expansion of wooden windows; When the moisture content of wood is lower than the humidity range, the wood will shrink due to water loss, and the wooden window will not crack, so the wooden window will not crack due to rain.
