Picture Windows can be used as a stand alone or companion window to add visual interest or capture a view. These windows are fixed
(non-operable) and typically let in the maximum amount of light, as they tend to be the largest window installed. Picture Windows
are often complemented by an architectural-style window above or casement, single-hung or double-hung windows on each side.
Picture Windows may also come in a variety of shapes such as square, rectangle, half round, quarter round, circle, oval, elliptical,
octagon, hexagon, trapezoid, eyebrow, triangle and peak pentagon. - See more at: http://www.pgtindustries.com/products/windows/all?type_style=38#sthash.K6rYlF76.dpuf
