ABSTRACT:
A plastic window framing for single or double glazing and single or multiple panes. The frames comprise mullions, glass stops, nailing fins and expansion strips extruded from modified polyolefins that are weather and ultraviolet degradation resistant. The glass stops and expansion strips are co-extruded integral combinations of a hard rigid plastic support and a very flexible sealing portion. Since both the hard rigid portion and the flexible sealing portion of the extrusions are of the same weather and ultraviolet resistant plastic, the plasticizer being the addition for flexibility, the entire framing including the seals can be exposed to the external environment and the mullions can be of relatively simple configuration.
The mullions are symmetrical about perpendicular planes longitudinal with the extrusion. The mullions of identical cross-section can be used for vertical and horizontal members of the frame including intermediate mullions between panes. Interior and exterior glass stops are identical in cross-section and can be interchanged and used for both single and double glazing without alteration of the glass stops or mullions.
