Driftless Foam delivers professional closed-cell and open-cell spray foam insulation in Decorah, Iowa that seals air leaks, reduces energy bills, strengthens buildings, and improves year-round comfort for Decorah homes, farms, and commercial properties in the heart of the Iowa Driftless region.
If your home, pole barn, or commercial building struggles with uneven temperatures, rising energy costs, condensation, or lingering drafts, your insulation is failing you
Driftless Foam specializes exclusively in professional spray foam insulation using premium materials and proven installation methods.
Unlike traditional insulation, spray foam expands on contact, filling cracks, seams, and voids to create a continuous air barrier. This dramatically reduces heat transfer, eliminates drafts, and protects against moisture intrusion.
Whether you need residential, agricultural, or light commercial spray foam insulation, we design the right solution for your structure and climate.
Decorah is one of the most beautiful communities in the Driftless Area set in the Upper Iowa River valley with bluffs, trout streams, and deep agricultural roots. It's also a place where winter arrives hard and stays long. Northeast Iowa's cold winters and humid summers put real stress on buildings, and insulation that can't keep up means higher bills, uncomfortable interiors, and gradual structural damage.
In Winneshiek County, temperature swings between seasons are dramatic. Attics bake in July and freeze in January. Crawl spaces accumulate moisture. Pole barns and equipment sheds that aren't properly sealed become expensive to heat and prone to condensation problems. Fiberglass insulation installed years ago may have already settled or absorbed moisture leaving your building exposed without you realizing it.
Poor insulation leads to:
Higher heating and cooling bills
Uncomfortable indoor temperatures year-round
Moisture buildup and mold risk
Long-term structural damage
Poor sound control
You deserve insulation that performs. Driftless Foam delivers it.
At Driftless Foam, we specialize in professional spray foam insulation that creates a powerful air seal while delivering superior thermal performance.

Spray foam can be applied to walls, ceilings, rooflines, attics, and other areas where insulation and air sealing are needed. The appropriate application depends on the building's construction and project requirements.
Spray foam can help reduce heat transfer and unwanted air leakage, which may allow heating and cooling systems to operate more efficiently. Actual energy savings depend on the building, existing insulation, HVAC system, and other factors.
