During the 1600s and still at the start of the 1700s, windows were small and placed in lead frames. Only during the last part of the 1700s did windows become larger and wooden frames come into use. The six-paned vertical window became standard in Raahe. The classic six-paned window later evolved into a transformation in which the two lowest panes were combined. The four-paned window with equal-sized pieces of glass has never been used as a window for residential buildings in Raahe.
