Shallow openings
34% of homes were built in 2000 or later. Newer windows are often set close to the room side of the wall, and handles, cranks and alarm sensors stick out into the space a louver swings through. Measure the depth to the glass and to anything that sticks out; the designer checks it against the louver size you pick.
Rounded drywall corners
63% of homes here were built from 1980 on, and many houses of that era have rounded ("bullnose") drywall corners around the windows instead of square returns. A shutter can't sit flat against a curve: choose an outside mount with a frame that clears the corner, or an inside mount if the flat part of the opening is deep enough for your louvers.

Cold winters
With 178 freezing nights a year, warm room air meets cold glass for months. Shutters closed tight overnight hold that air against the window, so condensation can collect on the sill: tilt the louvers open in the morning, and wipe the sill on windows that often run wet.
