Spray Foam Insulation in Speedway, IN

Spray foam insulation in Speedway works with an older, compact housing stock. Wikipedia says the town was laid out in 1912 as a residential suburb and incorporated on July 14, 1926. It grew from 1,420 residents in 1930 to 5,498 in 1950 and 14,523 in 1970, then leveled off; the 2020 census counted 13,952 people and 6,731 housing units in about 4.79 square miles. The Speedway Historic District was listed on the National Register in 2005. Most homes here were built well before modern energy codes.

Houses from the 1920s to the 1960s

The oldest homes may have balloon framing, plaster walls, attic rooms and stone or block foundations. The postwar homes are often small ranches and Cape Cods with crawl spaces or partial basements. Both groups tend to have thin or settled attic insulation, unsealed rim joists and drafty attic access. We work from the bottom up and the top down: seal the crawl space or basement and rim, then the attic floor, then decide whether wall work makes sense.

Cape Cods and attic rooms

Story-and-a-half houses have sloped ceilings and knee walls with small attic spaces behind them. Those are tough to insulate evenly with loose fill. Foam on the knee walls and the floor of the short attic behind them, plus separate treatment of the slopes and the top attic, is usually the plan.

Detached garages and workshops

Plenty of Speedway owners use a detached garage as a workshop. Foam in the walls and roof of a garage makes it possible to heat in winter and keeps the summer heat down. If the building has a steel roof, closed-cell foam stops condensation from dripping on cars and tools.

Climate

Wikipedia describes Speedway's climate as close to the line between humid continental and humid subtropical, with a January daily mean of 28F and about 40 inches of precipitation a year. Hot, humid summers and freezing winter nights both work on a leaky house.

Plaster walls and old attics

Older Speedway homes often have plaster walls and attics with board floors laid over part of the space. Insulating under a floored attic means pulling some boards or dense-packing from above. Where the attic is used for storage, we can raise a section with a platform so insulation goes underneath and storage stays on top.

Small houses, quick payback

On a small house, sealing the rim joist and attic floor covers a large share of the total air leakage. These jobs are usually done in a day.

Small lots, careful work

Homes sit close together on small lots, so we plan equipment placement and hose runs with neighbors in mind and keep the work area tidy. Get a free estimate
