Protruding sill

A protruding sill protrudes beyond the wall surface.

If your window sill protrudes, then we provide a trim frame on the left side, right side, and top of the window. On the trim frame part of the frame mounts inside the window and the trim molding overlaps onto the wall. On the bottom, a piece of frame sits flat on the window sill.

If your window sill does not protrude after selecting a full height trim frame shutter, we will provide a trim frame on all 4 sides that overlaps onto the wall.
