Patent ID: 11346147

Abstract:
A sill assembly that can include a sill and one or more threshold inserts. The threshold inserts can cover cavities within the sill. The sill assembly can optionally include a subsill, which can be a separate from or part of the sill. The subsill can include subsill cavities aligned over the sill cavities to form vertically-stacked pressure chambers. These vertically-stacked pressure chambers can include vertically-stacked pressure chambers positioned within the interior of the building, and vertically-stacked pressure chambers positioned within the exterior of the building. The sill assembly is so structured that different door types, such as swing doors, pivot doors, folding doors and/or sliding doors can be accommodated using the same sill and subsill by simply changing the threshold inserts. The sill assembly can have a minimal rise above the floor surface to meet regulatory requirements such as the Americans with Disabilities Act (ADA).
