Cut-away of a Vi6 terrace door corner on the standard sill, with a raised step and a drip edge
Standard sill

A step that keeps the weather out.

The standard sill is a raised step with a drip edge. Wind-driven rain has to climb the step before it can reach the room, so this is the sill behind the published water rating, and it is the sill on every terrace door, Vi6 and Vi5, unless the schedule says otherwise. The accessible sill is the alternative: flip the picture to see it.

Vi6 · standard sill

A raised step with a drip edge. The step is what holds water out, so this is the sill behind the published water rating.

Cut-away of a Vi6 terrace door corner on the accessible sill, low and flat
Vi6 · accessible sill

1/2 inch high, the limit the ADA sets for a new doorway. Flat enough to roll a wheelchair or a stroller across. Offered on the Vi6 in-swing door, and marked door by door on the shop drawings.

Cut-away of a Vi5 terrace door corner on the standard sill
Vi5 · standard sill

The same standard sill on the 70 mm (2-3/4″) frame.

On a building

The door is part
of the elevation.

Same frame, same color and same glass as the windows beside it, so a terrace door reads as one more opening in the wall. Black or white, single or paired, with a side light or without.
