Abstract
Embodiments herein relate to multi-part sill assemblies for fenestrations. In an embodiment, a multi-part sill assembly for a fenestration unit is included having an exterior sill subunit and an interior threshold subunit. The exterior sill subunit can be formed of a metal and the interior threshold subunit can be formed of a composite material. The interior threshold subunit can be joined to the exterior sill subunit by at least three different points of contact. The three different points of contact can include a pivoting joint; a locking joint; and an adhesive joint. Other embodiments are also included herein.
