Louvers for South Whittier

California shutters and plantation shutters are the same thing: panels of wide, tilting louvers fitted to the window. What sets one apart from another is mostly the louver size, and South Whittier's homes and sun point to different choices.

Here, about 39 days a year reach 90°F. That's fewer hot days than 52% of the 881 US cities we have climate figures for.

The midday sun climbs to 80° in June and sinks to 33° in December, so the louver angle that blocks it changes with the season.

In Whittier, 2 miles away, 29% of homes are apartments or condos, 10 points more than here.

Wide louvers for a view

76% of homes are detached houses with larger windows to the yard. 4½ in louvers mean fewer, wider slats and the most view when they're open, if the opening is deep enough for them to tilt.

Choosing a louver size

Tilting against the sun

On hot days, tilt the louvers so the room-side edge points down: high sun bounces off the slats while you still see out below them.

When in doubt, 3½ in

The middle size suits most windows and most depths, and it's the one most homes here would choose. The designer checks your depth against the louver you pick.
