Injection foam wall insulation · Fort Atkinson, WI

Fort Atkinson’s older homes deserve warm walls.

The homes along the river, the older neighborhoods off Main Street, the farmhouses and 1960s ranches on the edge of town — most were built with nothing in the walls. Cozy Walls fills them with injection foam from the outside, in a day or two, without touching a wall in your living space.

Erik lives on Lake Koshkonong. Fort Atkinson is home turf.

The Fort Atkinson problem

Jefferson County has some of the best-kept older housing in Southern Wisconsin — and some of the coldest walls. Three reasons:

  • Pre-war homes: plaster and lath inside, siding outside, and an empty cavity between them. Beautiful trim, no insulation.
  • Post-war ranches and farmhouses: batts that stop short of the top plate, or cellulose that settled decades ago.
  • Lake and river exposure: wind off the water finds every gap in an empty wall. A house on the Rock River or Lake Koshkonong leaks heat faster than the same house in town.
