Spray Foam Insulation in Ottawa, KS

Spray Foam Insulation in Ottawa works with an older town on both banks of the Marais des Cygnes River. Ottawa is the Franklin County seat and home of Ottawa University; the first non-Indian settlement went up in 1864. The town has flooded many times: in 1928 the river crested at 38.65 feet, and the Great Flood of 1951 covered one-third of Ottawa. Levees and pumping stations built by the Army Corps of Engineers in the 1960s now protect the town.

Basements and flood history

Homes in low areas may have basements that took water in the past. Closed-cell foam, which does not absorb water, is the right choice for rims and below-grade walls once the space is dry.

Older housing

Ottawa had 10,081 residents in 1950 and 12,625 in 2020, so most homes are long-established. Dense-pack walls, attic sealing and rim foam are the common projects.

Housing count

The 2020 census counted 5,558 housing units.

Code targets

Franklin County is in climate zone 4A; ENERGY STAR recommends R-60 for an uninsulated attic and R-49 added over 3 to 4 inches.

Farms

Franklin County farms have pole barns and machine sheds that benefit from closed-cell foam.

Rebates

If Evergy is your electric provider, its Kansas chart lists rebates for air sealing, R-38 ceiling insulation and rim joist insulation.

College rentals

Ottawa University brings student and faculty rentals. Landlords usually choose sealing plus blown-in and rim foam as practical upgrades.

Typical quote

Rim foam and closed-cell foam on below-grade walls, attic sealing with blown-in to R-49, and dense-pack walls in older homes, each on its own line so the work can be phased.
