are mounted within the window opening with a
molding extending out onto the wall around the window.Flush mounting requires "true"
(straight) window openings and adequate depth in the opening for the louvers to
open and close.It lets in slightly less light than surface
mounted shutters since the height and width of the panels are within the window
opening.
Inside
Mount
also require adequate depth because they attach completely
inside the window opening, and are most commonly used for passthroughs and for window
seats with exceptionally deep sills.
Important: If you have removable windows, and
are considering either flush or recessed mountings, discuss with your representative
whether there is enough wall-to-window depth to allow window or screen removal.
Outside
Mount
consist of a frame at least 2 inches deep that attaches
to the wall outside the window opening. Surface mounting works on almost any
window, and displays more wood framing than flush mounting. The panels are slightly wider
and allow more light to enter.Surface mounting is far and away the best and
least expensive method for mounting shutters on arched windows because arches are rarely
"true".
