Wood is a natural material that constantly absorbs and releases moisture. Therefore the frame should not be exposed to extremely high or too low humidity (e.g. during the heating period). Otherwise the wood begins to work again, to warp, to show open glue joints or cracks.
ATTENTION! In winter, make sure that you keep the wooden frame in a dry and frost-free place!
The frame should be varnished again after a few years.
