Aluminum window frames are made from extruded aluminum alloy and can include a multitude of additional features depending on desired application and performance. Because aluminum conducts heat readily, windows used in colder climates, commercial construction, and/or multifamily housing are most commonly thermally broken, meaning they employ a non-conducting plasitc material between interior and exterior portions of the window frame to improve thermal properties. These thermal breaks are most often polyamide strips that form a bridge between aluminum pieces or poured-in-place polyurethane that performs a similar function. While other plastics may be used for thermal breaks, these are the most common types and applications. Windows may have either type of thermal break or both. This CP includes an aluminum window frame with both polyamide and polyurethane thermal breaks as well as an anodized coating. Other common coatings include PVDF and powder coatings, which are included in the All Contents. This CP is meant to represent only the frame itself and excludes other window components that may be used with all types of frames such as glass pane(s), films, sealant, seals, spacers, gas fill, and hardware.
