Insulating Grand Blanc's 1960s and 1970s Homes

Spray Foam Insulation in Grand Blanc mostly means upgrading homes built in the 1960s and 1970s. Point2Homes' census summary shows 27.8% of the city's homes date from the 1960s and 24.1% from the 1970s, more than half the stock. Only 53.9% of units are detached houses, so we also work in condos and attached homes where shared walls and attics need careful planning.

Settled in 1822

Grand Blanc was first settled by Jacob Stevens in 1822, grew after the railroad arrived in 1864, and incorporated as a city in 1930. In February 2024 an EF2 tornado with winds near 115 mph tracked 5.7 miles through the area, the strongest on record for Grand Blanc. Homes that were repaired after storm damage are a good chance to air seal and insulate while walls and roofs are open.

What 1960s and 1970s houses need

These houses have some insulation, just not much: often 3 to 4 inches in the attic and a thin batt in 2x4 walls. The Department of Energy recommends adding R-49 on top of 3 to 4 inches in an existing Zone 5 attic. Air sealing the top plates and recessed lights first makes that added depth pay off. Rim joists usually have a loose batt or nothing.

Condos and attached homes

In attached units, we work only on the spaces that belong to your unit and check association rules before quoting. Foam on the rim joist and a sealed attic hatch are common jobs that stay inside your unit.

Code targets

Genesee County falls in Climate Zone 5A, where Michigan's residential code table lists R-38 for ceilings and R-10 continuous or R-13 cavity for basement walls. For older homes we usually aim higher in the attic.

Recessed lights and bath fans

Houses from the 1960s and 1970s often had recessed lights added later, and many older cans are not rated for insulation contact. Each one is a hole into the attic. We cover them with fire-rated boxes or seal them with proper covers before insulating. Bath fans get ducted to the outside, since a fan that blows moist air into the attic causes frost on the nails in winter and stains on the ceiling in spring.

What R-value do you aim for in a Grand Blanc attic?

Older cans not rated for insulation contact need covers or sealing before insulation goes over them.
