Spray Foam Insulation in Shelbyville, IN

Spray foam insulation in Shelbyville covers homes in the county seat and the farm buildings around it. Wikipedia describes Shelbyville as the seat and the only incorporated city in Shelby County, about 26 miles southeast of downtown Indianapolis, sitting at about 761 feet where the Little Blue and Big Blue rivers meet. The county's low rolling hills are given over mostly to agriculture or development.

Storms and building design

The National Weather Service lists 34 tornadoes in Shelby County from 1950 to 2025, including one F4 and six F3s. Shelby County's design values under Indiana's 2020 residential code include a 115 mph wind speed, 20 psf ground snow load and 30-inch footing depth. Those values govern framing, but they are also a reminder that wind across open ground pushes air through every gap in a house, which makes air sealing worth doing.

Homes near the rivers

Homes on low ground near the two rivers need a moisture check before crawl space or basement insulation. Central Indiana's Crosby soils are somewhat poorly drained, with a perched water table close to the surface in winter and spring, according to the USDA.

Older homes in town

Older homes near Shelbyville's center can have crawl spaces, plaster walls and attics that have never been brought up to modern depth. Sealing and topping up the attic, dense-packing thin walls and closing a dry crawl space are the usual upgrades, done in the order that gives the most comfort for the budget.

Barns and shops

With farm ground on every side, pole barns and steel shops are a big part of the work around Shelbyville. Closed-cell foam on steel walls and roofs stops condensation and holds heat. Get a free estimate
