Abstract
A thermally enhanced extrudate includes a channel, a first wall, and a second wall. The channel extends along a longitudinal axis from a first end to a second end of the thermally enhanced extrudate and is shaped to receive glass or a frame. The second wall is spaced from the first wall. The first wall and the second wall partially enclose a thermal break extending along the longitudinal axis. The thermal break has a first width defined between the first wall and the second wall at an upper end of the thermal break and a second width defined between the first wall and the second wall at a lower end of the thermal break. The thermally enhanced extrudate further includes a solid insulation material in the thermal break between the first and second walls and formed by curing a flowable material.
