Andersen Corporation - Bayport MN

International Classification:

E04C 226

US Classification:

428 34, 428 357, 428 369, 4282974, 428 52, 4287303, 4287304

Abstract:

A complex profile made of a composite comprising a polyolefin polymer and a wood fiber. The composite is useful in conventional structural applications. The profile can be used in residential and commercial structures. The profile is used in the manufacture of the fenestration components such as windows and doors. The profile is designed with a cross-sectional shape to form structural elements in the fenestration units that possess sufficient strength, thermal stability and weatherability. The member comprises a hollow cross-section with at least one structural web or one fastener web. The profile can have a visible capstock layer and can be assembled using thermal welding processes.

Abstract:

A member comprising a complex profile made of a composite comprising a polypropylene polymer, and a wood fiber. The composite is useful in construction applications. The profile can be used in residential and commercial structures. The member is used in fenestration components such as windows and doors. The members possess strength, thermal stability and weatherability. The member comprises a complex cross-section with at least one structural web or one fastener web. The exterior can contain a cap-stock and is shaped for use in a fenestration unit such as a window, sash or movable door unit. The members can be assembled in thermal welding processes.

C08K 3/40

US Classification:

524494, 264299, 524492, 524493

Abstract:

The invention relates to a hot melt dispensable polymeric composite and process for making and using the composite. Particulates of adequate particle size are mixed with a polymer that exhibits low viscosities at temperatures typically provided by hot-melt glue guns to form rods that vary significantly in density from the base polymer. Novel articles can be manufactured by dispensing the composite from a glue gun into molds or by placement of the melt molding compound into preformed cavities within an end article.

International Classification:

US Classification:

428/036900

Abstract:

An improved composite structural member comprising a complex profile structural member, made of a composite comprising a polypropylene polymer and a wood fiber. The material is useful in conventional construction applications. The complex profile, in the form of an extruded thermoplastic composite member can be used in residential and commercial structures as described. Preferably, the structural member is used in the manufacture of the fenestration components such as windows and doors. Such linear members are designed with specifically configured cross-sectional shapes to form structural elements in the fenestration units. Structural elements must possess sufficient strength, thermal stability and weatherability to permit the manufacture of a structurally sound window unit that can be easily installed into a rough opening but can maintain its attractive appearance and structural integrity over the life of the window unit often twenty years or more. The structural member comprises a hollow complex cross-section with at least one structural web or one fastener web formed within the component. The exterior of the extruded component has a visible capstock layer and is shaped and adapted for installation in rough openings. The exterior also contains shape and components capable of supporting the elements of the fenestration unit such as a window, sash or movable door unit. The improved polypropylene structural members have unique advantages and can be assembled in thermoplastic weld processes.
