In-Swing doors use Sun’s, Standard In-Swing Sill. An ADA, low-profile sill is available if it is required by your project.
Out-Swing doors use Sun’s, Standard Out-Swing Sill. An ADA, low-profile sill is available if it is required by your project.
Bi-Fold Doors and Windows have three sill options. The Standard sill sits on top of the subfloor surface and has a 2-3/16” total height above the subfloor surface. The ADA sill has a 1/2” height above the finished floor surface but requires a cut-out under the track channel area of the sill. The U-channel is 7/8” high and must be set in a recessed groove so that the top is flush with the finished floor surface.
