Homes in Sarnia
Sarnia is a city of houses: of its 32,190 occupied homes, 67% are detached, 10% are semi-detached and row houses and 23% are apartments or units in buildings of two or more homes.
More homes here were built 1960 or earlier than in any later period we count: 36%. Only 11% date from 2001 or later. 68% of homes are lived in by their owners.
Its housing is much like Chatham-Kent's, 63 km away. Nationally, Sarnia's homes are older than those in 95% of the 167 Canadian cities we have census figures for.

Plaster walls and deep casings
36% of homes date from 1960 or earlier, when walls were plaster on lath and windows sat in deep wood casings. Plaster cracks if you drive screws carelessly: drill a pilot hole, use fixings made for plaster, and fix into the casing or the framing behind it. A deep casing is good news for an inside mount; measure its depth before you choose a louver size.
Out-of-square openings
With 71% of homes built in 1980 or earlier, 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 6 mm, add a mounting frame in the designer, or choose an outside mount so the shutter covers the uneven edges.
Whole-house orders
With 67% 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.
Replacement windows
35% of homes went up between 1961 and 1980, and most of them have had their original windows replaced since. A replacement window often sits further into or out of the wall than the old one, so the depth you have for an inside mount may differ from window to window in the same house. Measure every opening rather than copying one.

Summer sun
On the 15 days a year above 30 °C, closed louvers keep direct sun off the glass and out of the room. In a window that takes afternoon sun, white and light paint finishes stay cooler to the touch than dark stains.
Cold winters
With 131 days at or below freezing 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.
