Spray Foam Insulation in Madeira, OH

Spray foam insulation in Madeira is mostly about homes from one decade. ACS data on Point2Homes shows the 1950s produced about 29.5% of Madeira's housing, and the median year built is 1960. Wikipedia records the population jumping from 2,689 in 1950 to 6,744 in 1960. Those ranches, Cape Cods and split-levels were built with a few inches of attic insulation, little or nothing in the walls, and no air sealing at all.

Ranches and Cape Cods

A one-story ranch has a large attic floor relative to its living space, so the attic is where it loses the most. Sealing the top plates and penetrations, then blowing cellulose or fiberglass to depth, typically makes the biggest difference. A Cape Cod has a different problem: its upstairs rooms sit under sloped ceilings with short knee walls and pockets of attic behind them. Those knee walls and the floor behind them are often barely insulated and wide open to air. We seal and insulate those spaces, sometimes with foam where the framing is tight.

Older and newer neighbors

Madeira is not all 1950s. About 10.9% of the housing predates 1940 and another 10.4% dates from the 1940s, while roughly 14.5% went up between 2010 and 2019, many as replacements for older houses. A street can hold a 1930s frame house next to a new build, and the plans for those two houses look nothing alike.

Owners who stay

About 92.2% of occupied homes in Madeira are owner-occupied, and detached single-family houses make up 91.2% of the housing. Owners who plan to stay tend to want the full picture, so we usually look at attic, walls and basement together and lay out the order that gives the most comfort for the money.

Zone 4A targets

Madeira is in Hamilton County, assigned to Climate Zone 4A in Ohio's residential energy code. That table lists R-49 for ceilings and R-19 for floors over unheated space, which is the benchmark we use when sizing attic depth or a floor over a porch or crawl space.
