Spray Foam Insulation in Avon, IN

Spray foam insulation in Avon is mostly about homes built in the last thirty years. Wikipedia says the area was first settled around 1830, but Avon did not incorporate as a town until 1995. The population went from 6,248 in 2000 to 12,446 in 2010 and 21,474 in 2020, and the town's area grew from 14.34 square miles in 2010 to 19.41 square miles. The 2020 census counted 8,231 housing units.

What we find in Avon homes

Most Avon homes are two-stories and ranches in subdivisions. Their insulation meets the code of the year they were built, but code is a minimum and the leaks are in the details. The rim joist, the floor over the garage, the attic hatch, can lights and knee walls are where we spend most of our time. Many homes have bonus rooms or bedrooms over the garage that run hot in summer and cold in winter.

Attic depth above code

The 2020 Indiana Residential Code lists R-38 for ceilings in Climate Zone 5, per the Insulation Institute's summary, and Hendricks County is in Zone 5A, per OpenEI. The Department of Energy recommends R-60 for an uninsulated attic in that zone. In many Avon homes, sealing the attic floor and adding blown-in on top of the builder's insulation is one of the most cost-effective upgrades.

Basements and crawl spaces

Avon homes sit on a mix of basements and crawl spaces. For basements, the rim joist and walls are best done before finishing. For crawl spaces, a sealed liner and foam on the walls and rim keep the space drier through humid summers.

Recessed lights

Many Avon homes have recessed can lights in the top-floor ceiling. Older cans leak air into the attic. We seal around them or recommend airtight covers, depending on the fixture type.

Crawl spaces in newer homes

Even new homes on crawl spaces can run damp in summer. A sealed liner and closed vents help, and we check for water first.

Homes on newly annexed land

As Avon added land between 2010 and 2020, new subdivisions went up on former farm fields. Open lots catch more wind until trees grow in, and wind pushes air through any gap in the shell. Sealing the rim, the attic floor and the garage ceiling makes a noticeable difference in a house on an exposed lot.

Growth means construction nearby

With the town still adding land and homes, many owners are in houses only a few years old. If something in your new home just does not feel right, like a cold room or a hot room, it is worth checking the usual spots before assuming the HVAC system is the problem. Get a free estimate
