Homes on Slopes and Ravines

Spray foam insulation in Delhi Township is shaped by its terrain. Wikipedia describes slopes running down to the Ohio River floodplain with numerous ravines cut by streams. Houses here sit on hillsides, at the tops of ravines and along winding roads, and a lot of them have exposed foundations, walkout basements or crawl spaces under additions. The township was once called the Floral Paradise of Ohio, with as many as 55 family-run greenhouses, and some of that land later filled with houses.

Exposed foundations

When a lot falls away, part of the foundation stands above grade. That exposed concrete and the rim joist on top of it lose heat all winter. Closed-cell foam on the rim and on the inside of the exposed walls reduces that loss and keeps humid summer air from condensing on cool masonry.

Crawl spaces under additions

Many houses in Delhi have a basement under the original house and a crawl space under a later family room or kitchen addition. Those crawl spaces are often vented, with fiberglass between the joists. In summer, humid air flows in, the batts take on moisture and fall, and the floor above stays cold in winter. Closing the crawl space with sealed vents, a vapor barrier and closed-cell foam on the walls fixes both problems.

A dense, settled township

Wikipedia lists 28,760 residents and 11,060 housing units on about 10.1 square miles in 2020, and Mount St. Joseph University sits in the township. Homes range from early 20th-century houses near the river to post-war ranches and later two-stories on the ridges.

Zone 4A

Delhi Township is in Hamilton County, which Ohio's residential energy code assigns to Climate Zone 4A. The state table's crawl space wall value is R-10 continuous or R-13, which closed-cell foam reaches in a couple of inches.

Hillside attics

Houses on Delhi's ridges catch more wind than those in sheltered valleys. Wind pushes air into the house on one side and out the other, and the attic floor is where much of it escapes. Air sealing the attic floor is the first job on most of these homes.

Delhi Township Questions

My addition's floor is cold. Is it the crawl space?

Very often. A vented crawl space with fallen batts leaves the floor exposed to outdoor air. Closing and insulating the crawl space walls usually fixes it.

Can you insulate a crawl space with a dirt floor?

Yes. A heavy vapor barrier goes over the dirt and up the walls first, and then the walls are insulated.

Do you work on houses down near the river?

Yes. Lower-lying houses can have more moisture in basements and crawl spaces, so we check for water before planning insulation.
