Insulation in Minnesota's Energy City

Elk River has been thinking about energy for a long time, which makes spray foam insulation a natural topic here. The Minnesota Environmental Initiative named Elk River an "Energy City" in October 1997, and the town has hosted unusual power projects, from a rural nuclear demonstration plant that went online in 1960 to a Great River Energy plant converted in the late 1980s to burn refuse-derived fuel. At the household level, the most reliable energy project is still the simplest one: keep the heat inside.

The climate we plan for

Elk River's record low is -40 F, and the mean daily high in January is just 23.1 F. The city averages 39.5 inches of snow a year. That combination of long cold and steady snow is what produces ice dams on houses with warm attics. Air sealing the attic floor and adding depth toward the DOE's R60 target for uninsulated attics in its coldest zones is the core of most of our Elk River work.

A big city footprint

After consolidating with the surrounding township in 1978, Elk River covers about 43.85 square miles. That much ground can include in-town homes, subdivisions and acreage with outbuildings. A shop or pole barn on acreage calls for closed-cell foam on the steel to stop condensation; a 1990s two-story calls for attic and rim work; an older house near downtown may also need wall insulation.

Basements and rim joists

Sherburne County is in Minnesota's Zone II for frost, with footings at least 3-1/2 feet deep. Basement walls stay cold, and the rim joist sitting on top of them is one of the biggest leaks in most homes. Closed-cell foam handles both the air and the moisture there. The DOE notes that open-cell foam should not go below grade.

A steady housing market

The 2020 census counted 9,474 housing units in Elk River with a homeowner vacancy rate of just 0.4%. Owners tend to stay, and that makes long-term efficiency work worthwhile.

Elk River Questions

What R-value should my Elk River attic have?

The DOE recommends R60 for an uninsulated attic in its coldest zones, and adding R49 where 3 to 4 inches already exist. We measure your current depth and plan from there.

Do you work on rural Elk River acreage?

Yes. Homes, detached garages and pole buildings across the city's 43-plus square miles. Each building gets its own line in our quote.

How does spray foam help with ice dams?

It seals the air leaks that let attic heat warm the roof. When the roof stays cold, snow does not melt and refreeze at the eaves.

Is closed-cell foam worth the extra cost in a basement?

For rim joists and foundation walls, yes. It resists moisture and carries more R-value per inch than open-cell, which the DOE says should stay above ground.
