The construction and material used in the frame of the fenestration product. Some frames are made of combinations of materials. This characterization also include whether an aluminum frame has a thermal break as part of the construction
List Options |
Option Definition | Unit of Measure | |
|---|---|---|---|
| Aluminum no thermal break | A fenestration framing system composed of aluminum, but without any low conductance material in the system that would prevent thermal bridging, so that heat can flow unrestricted through the highly conductive aluminum material from the outside to the inside of the frame. | None | |
| Aluminum Thermal break | A fenestration framing system composed of aluminum, which is a highly conductive material, that has one of more elements of low conductance material which reduce the flow of heat through the frame. | None | |
| Aluminum uncategorized | A fenestration framing system composed of aluminum, when it cannot be determined whether or not there is a thermal break in the framing system. | None | |
| Clad | A fenestration framing system composed of more than one material, such as wood on the interior of the frame and fiberglass or aluminum on the outside of the frame. | None | |
| Composite | A fenestration framing system composed of a blend of different materials. The most common type is a resin based blend of wood and plastic. | None | |
| Fiberglass | A fenestration framing system composed of fiberglass | None | |
| None | None | None | |
| Not applicable | Not applicable | None | |
| Other | Other | None | |
| Steel | A fenestration framing system composed entirely of steel. | None | |
| Unknown | Unknown | None | |
| Vinyl | A fenestration framing system composed entirely of vinyl. | None | |
| Wood | A fenestration framing system composed entirely of wood. | None |
