Whole-house orders

With 70% of homes detached, most orders here cover a whole house: bedrooms, a patio door, perhaps a bay. Put every window in one list in the designer so the louver size and colour match from the street, and if you have an HOA, send it the drawings before you order.

Bay window shutters

Shallow openings

33% 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.

Choosing a louver size

Out-of-square openings

With 49% of homes built before 1980, many openings have had decades to settle. Measure each one's width at the top, middle and bottom, and both diagonals. If the diagonals differ by more than about ¼ inch, add a mounting frame in the designer, or choose an outside mount so the shutter covers the uneven edges.

Cold winters

With 140 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.

Dry air

Only 9.2 inches of precipitation a year, and days and nights about 26°F apart. Dry air pulls moisture out of wood, so poplar louvers can shrink very slightly through their first dry season; that's normal for real wood.
