What is a Picture Window?
Definition of Picture Window in Construction Used to describe an assembly of windows, consisting of a larger fixed glass window in the center, flanked by casement or double hung windows. In some instances the term is used to merely identify a large section of fixed glass without any flanking windows. The term originated due to the overall effect of the visual look of the window from the interior of the structure. Normally the casing is a continuous window frame with no sill or apron.
