Vinyl shutters in Boulder: vinyl or wood?

Vinyl is cheaper and waterproof; solid wood can be sanded, repainted and made in any colour. Which suits Boulder's weather and homes, room by room.

Boulder's weather and homes

In Boulder, July averages a high of 88°F and December a low of 21.1°F, about 33 days a year reach 90°F, 138 nights fall at or below freezing, and 19.8 inches of precipitation falls in a typical year. That's fewer hot days than 56% of the 881 US cities we have climate figures for.

55% of homes were built before 1980, and owners live in 47% of them.

Broomfield, 12 miles away, has 53 days a year at 90°F or more, more than Boulder's 33.

Dry winters

Here's a fair point for vinyl: it doesn't take on or give off moisture, so dry heated winters don't move it. Wood moves a little with the seasons; paint and a sensible indoor humidity keep it small.

Why poplar

Uneven openings

In older homes, openings are rarely square. Wood can be lightly sanded to fit at install; vinyl can't be sanded at all.
