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.

1. A frame structure comprising: a reinforcing member having an outer surface and at least a portion that has a substantially hollow interior, a plurality of lobes formed in said reinforcing member that have an interior lobe dimension that is larger than a lobe waist opening;a first plastic layer that is disposed in said lobes and extends into said lobe waist opening;an exterior plastic layer that is disposed on substantially all of said outer surface of said reinforcing member, and that is attached to said first plastic layer, said exterior plastic layer disposed on said reinforcing member in a contracted state that holds said exterior plastic layer securely to said reinforcing member;a recess formed in said reinforcing member, that is covered by said exterior plastic layer, and that secures an insert to said frame structure;a removable bracket that is attached to said support structure that supports said insert and allows said insert to be removed from said recess in said frame structure whenever said removable bracket is removed from said reinforcing member. 2. The frame structure of claim 1 wherein said frame structure comprises a non-structural frame member. 3. The frame structure of claim 2 wherein said frame structure comprises a mullion. 4. The frame structure of claim 3 wherein said insert comprises a window. 5. The frame structure of claim 3 wherein said insert comprises a photovoltaic detector. 6.
