Spray Foam Insulation in Two Harbors, MN

Spray foam insulation in Two Harbors works on homes facing Lake Superior head-on. The town grew from a railroad construction camp at Agate Bay in 1883; the first iron ore cars left in 1884, and Two Harbors was platted in 1885. The 2020 census counted 1,750 housing units here with 9.3 percent vacant, a higher share than Duluth's suburbs, reflecting seasonal homes and cabins.

Lake weather

The Two Harbors station's 1991-2020 normals show a January average low of 7.4F, about 61 inches of snow a year and a record low of -36F. Wind off the lake drives cold air into gaps at sills, rim joists and windows. Inland stations just northwest get even more snow.

Cabins and seasonal homes

Owners converting a seasonal place for winter use usually need the rim joist, crawl space or basement, and attic sealed and insulated. Closed-cell foam is common in crawl spaces and floors over open air.

Older port-town houses

In town, older homes from the railroad and ore-dock era need attic air sealing and foundation work, much like Duluth's.

Planning for seasonal use

If a home sits empty part of the winter, tell us how warm it is kept. A cabin held at 45F has different needs than one heated to 68F year round, and the plan should match how it is used.
