Spray Foam Insulation in Olathe, KS

Spray Foam Insulation in Olathe mostly involves homes built in the last 50 years. John T. Barton founded Olathe in 1857, and it became the Johnson County seat in 1859, but it stayed small until I-35 linked it to Kansas City in the 1950s. From 10,987 people in 1960 it grew to 63,440 in 1990 and 141,290 in 2020, spreading into farm fields to the south, west and north of the original town. The 2020 census counted 51,820 housing units.

What we find

In 1970s and 1980s homes: thin attic insulation, uninsulated rim joists and gaps around fixtures. In 1990s and newer homes: bonus rooms over garages, kneewalls with missing batts, recessed lights and minimum-depth attics. In nearly all of them: a rim joist that leaks along the whole basement.

Climate in both directions

Olathe averages about 36 days a year at 90F or above and about 102 days below freezing, with winter snow averaging about 19 inches. Insulation and air sealing work year-round.

Codes

The City of Olathe adopted the 2018 IRC and 2018 IECC effective September 1, 2019. Building code questions go to the Building Codes Division at 913-971-6200.

Family homes

Of 50,070 households in 2020, 40.1% had children under 18. Bigger households make more heat and moisture inside, and a sealed, well-insulated house handles both better.
