Abstract
Extruded plastic profiles with integrated insulation, the method for extruding such products, and the windows and doors made with such plastic extrusions. The plastic extrusions may additionally include a low heat build-up capstock system comprising an acrylic cap and pigment system that is substantially IR transparent. The extruded plastic profiles with integrated insulation are recyclable using conventional plastic extrusion process and are fully weldable in conventional window and door manufacturing.
Claims17
A window for use in a residential or commercial structure, comprising:
- a glass pack operatively installed in a window frame, where the window frame further comprises:
- a structural extrusion formed of a first thermoplastic resin suitable for use in the fenestration industry and which contains at least one hollow interior portion and which is of a constant profile and extends to an indefinite length, an integrated insulation formed of a second thermoplastic resin substantially filling at least one hollow portion of the structural extrusion, where the first thermoplastic resin and the second thermoplastic resin are compatible and recyclable together and where the structural extrusion and the integrated insulation are coextruded through an extrusion die.
A method of producing an extrudate with integral foam insulation, comprising the steps of:
- feeding a first thermoplastic resin suitable for use in a structural component in the fenestration industry into a first extruder;
- feeding a second thermoplastic resin suitable for integrated insulation into a second extruder;
- outputting the first and second extruders to an extrusion die extruding the extrudate, where the extrusion die forms the structural extrusion formed of the first thermoplastic resin, suitable for use in the fenestration industry, containing at least one hollow interior portion, of a constant profile, and extending to an indefinite length, and, substantially fills the hollow portion of the structural extrusion with an integrated insulation formed of a second thermoplastic resin.
A method of producing an extrudate with integral foam insulation, comprising the steps of:
- extruding a first thermoplastic resin to define a structure suitable for use in the fenestration industry;
- the structure having a longitudinal direction;
- extruding a second thermoplastic resin in the form of a plurality of foamed strands disposed within the structure to define a plurality of longitudinal air pockets disposed within the structure;
- bonding at least some of the foamed strands to the structure to form an integral insulated structure.
