Practical Insulation in Foley
Most spray foam insulation jobs in Foley involve one of two things: an older home in town or a building on a nearby farm. Foley was founded in 1890 and named after John Foley, and it serves as the Benton County seat. The town itself is compact, at about 2.5 square miles, but it is surrounded by farm country with plenty of outbuildings.
Older homes in town
Houses from Foley's early decades usually have plaster walls with little insulation, partial basements and attics that leak heat into the roof. Our first step is sealing the attic floor at chases, top plates and the chimney. Then we add blown-in insulation to depth. In the basement, closed-cell foam at the rim joist seals out drafts. Closed plaster walls are usually better served by blown insulation dense-packed through small drilled holes than by spray foam.
Mid-century and newer homes
Foley also has houses from the decades since, each with its own weak spots. Ramblers often have low attics at the eaves where insulation gets thin; split-levels have rim joists at several heights. We look at what is there before recommending anything.
Shops and farm buildings
Steel buildings around Foley sweat when heated. Closed-cell foam on the steel stops that and adds insulation. Benton County buildings are designed for a 50 pound per square foot ground snow load under state rule, which affects roof framing and how much weight a sprayed roof adds (very little).
Frost
Benton County falls in Minnesota's Zone II, with a 3-1/2 foot minimum footing depth for frost. The ground against a foundation wall freezes deep, so the rim and upper wall are worth insulating.
Housing
The 2020 census counted 1,060 housing units in Foley, with a homeowner vacancy rate of 0.6%. The 2020 median age was 34.0.

Foley Questions
Will spray foam put much extra weight on my shop roof?
Very little compared with a winter snow load. Closed-cell foam is lightweight, and it can actually stiffen steel panels.
My Foley rambler has cold spots near the outside walls of the ceiling. Why?
Ramblers often have thin insulation at the eaves where the roof slopes down. Sealing the top plates and using baffles or foam there helps keep full depth out to the edge.
Do you insulate split-level homes?
Yes. Split-levels have rim joists at several heights and often a garage under part of the house, so we check each level separately.
Will you come out to farms near Foley?
Yes, we work on homes and buildings in the countryside around Foley too.
