Insulation in a Hillside Iowa Town
Spray Foam Insulation in Glenwood covers an older Iowa town set in a hollow of the Loess Hills on the east side of the Missouri. Glenwood grew during the California Gold Rush around the grain mill on Keg Creek, and by the late 1800s it was known across Iowa for its fruit, especially apples. Many of its older homes date from that long settled period.
2019 flooding
Mills County had catastrophic flooding in March 2019, and Pacific Junction, just west of Glenwood, was nearly completely flooded. Homes that took water and were rebuilt have had their insulation replaced; others nearby may have damp crawl spaces or basements that were never fully dried. We check below-grade spaces before recommending any insulation, and we remove wet or contaminated material first.
Iowa code
Glenwood follows Iowa's residential energy code, the 2012 IECC with state amendments. The Insulation Institute's guide puts Mills County in Climate Zone 5, with R-49 ceilings, R-20 walls and R-15 or R-19 basement walls for new homes. Iowa's rule leaves remodeling of one- and two-family homes outside the code, so upgrades are your choice, not a requirement.
Hillside basements
Homes built into the hills have walkout basements and exposed walls. Closed-cell foam on the rim and the framed walkout wall, after any moisture is handled, turns a cold lower level into usable space.

Glenwood Questions
Our house took water in 2019. Should the insulation be checked?
Yes, if it was not replaced. Insulation that got wet can hold moisture and odor. We check and remove what needs to go.
Do you work in Glenwood and Pacific Junction?
Yes, both are in our Iowa service area.
Is my Glenwood house required to meet the energy code?
Not for upgrades. Iowa's rule leaves remodeling of one- and two-family homes outside its scope. The code values are still a good target.
