A frame made of moldable material is described for retaining a closure member, such as a window, in a door or wall opening. The frame is formed by interconnecting a peripheral main frame member, an outer peripheral casing connecting molding and inner peripheral sash connecting molding. The main frame member has an outer sash section, a side jamb section and an inner casing section. The outer casing connecting molding is adapted to be snappingly secured to the main frame member to clampingly retain the main frame member to a frame forming the opening. The inner sash connecting molding is adapted to be snappingly secured to the main frame member and has a bridge wall section to abut against a peripheral section of the closure member to retain it captive between the outer sash section and the inner sash connecting molding.
