Various aspects of the disclosure relate to modular sill systems for sliding panel doors and windows, collectively 'sliding fenestration units.' In various examples, modular sill systems include multiple separate and distinct base components that provide tracks on which one or more panels are able to slide.

Sill systems for sliding fenestration units

According to some embodiments, a multi-panel door system includes a fixed panel and an active panel. Both panels are secured to the astragal of the door frame by securement members driven into and through hinges connected to the active panel, through the astragal, and into the fixed panel. The securement members are driven through a middle portion of the astragal stem in order to align the fixed and active panels in a recessed position with respect to the door frame. The fixed panel and the active panel are coplanar. Hinge support plates are placed between the hinges and the astragal and communicate forces transmitted through the securement members into deeper portions of the astragal.
