Auburn Homes and Farm Buildings
Spray Foam Insulation in Auburn covers a small city and the farm country around it. Auburn was first settled in 1854, got a post office named Skinner in 1869 that was renamed Auburn in 1877, and incorporated as a city in 1947. The 2020 census counted 2,068 residents and 972 housing units, only 3.3% of them vacant, in about one square mile. The 48611 ZIP code is shared by surrounding Williams Township and much of southwestern Bay County.
In town
Auburn's homes are mostly established houses with basements. The usual list: rim joists that were never insulated, attics that need sealing and depth, and garages that leak cold into adjoining rooms.
Out in the township
Farms and rural lots around Auburn have pole barns, shops and detached garages. Closed-cell foam on steel or wood framing makes a building heatable and stops condensation.
Between two cities
Auburn sits between Bay City and Midland, so we often pair jobs here with work in both. Scheduling is straightforward.
What we recommend most
Rim joist foam, attic sealing and blown-in to R-49 or more, and closed-cell foam for any outbuilding that will be heated.
Cold-weather work
In winter, unheated garages and barns need surfaces warm enough for foam to cure. We plan for that when we schedule.
Climate zone
Bay County, including Auburn, is in IECC climate zone 5A. Michigan's updated residential energy rules raise new ceilings to R-60 in that zone, and ENERGY STAR recommends R-60 for an attic with no insulation.
Rebates
If Consumers Energy supplies your gas, its chart lists rebates for attic, wall, basement and rim joist insulation. Applications must be received by December 31 for the listed amounts.
