Abstract
Disclosed are frame members and mullions for a window frame that comprise a reinforcing member that is surrounded by an outer plastic layer. The outer plastic layer is held securely to the reinforcing member as a result of a waist banding effect that comprises an inward force created by the outer plastic layer as it cools and contracts around the reinforcing member. In addition, lobes are formed in the reinforcing member that assist in holding the outer plastic layer to the reinforcing member. Window inserts can be removed and replaced using adapters and removable brackets. Frame members and mullions can be built sufficiently strong to provide structural support. The frame can also be used to hold photovoltaic cells and protective coverings for photovoltaic cells. Structural members are also disclosed that have reinforcing members with apertures, debossing, scarification and/or indentations that secure the thermoplastic layer to the reinforcing member.
