Uneven temperatures, rising energy costs, condensation, and drafts aren't just annoyances — they're signs your insulation is failing you, whether it's your home, pole barn, or commercial building.
Spray foam insulation is our only focus at Driftless Foam — backed by premium materials and proven methods that get the job done properly.
Unlike ordinary insulation, spray foam expands instantly to fill every crack, seam, and hidden void — creating a seamless barrier that blocks heat loss, eliminates drafts, and keeps moisture firmly outside where it belongs.
Whatever your building — home, barn, or commercial space — we take the time to understand your structure and local climate before recommending the spray foam solution that's right for you.
Lancaster is Grant County's seat — a working city surrounded by farmland, ridge lines, and the kind of Wisconsin winters that make poor insulation painfully obvious. When cold air is finding its way in and your heating system can't keep up, your insulation is the problem.
Grant County's climate is demanding in every season. Frigid winter temperatures drive heat out of under-insulated homes and farm buildings, while summer humidity pushes moisture into walls and crawl spaces where it doesn't belong. Fiberglass batts — the insulation standard in most Lancaster-area homes and outbuildings — compress over time, leave gaps at framing edges, and absorb moisture. The result is a building that works harder, costs more, and gradually deteriorates from the inside out. For Lancaster's many agricultural operations, that means equipment exposed to condensation, stored goods at risk, and structures that age faster than they should.
If left unaddressed, 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 is ready to deliver it.

Commercial spray foam insulation is an insulation solution designed for commercial buildings and larger structures. It expands and adheres to surfaces to help reduce heat transfer and seal gaps where unwanted air can enter or escape.
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.
Yes. By reducing drafts and unwanted airflow, spray foam can help create more consistent indoor temperatures and improve comfort for employees, customers, tenants, and other occupants.
Yes. Spray foam can be installed in many existing commercial buildings. The structure and existing conditions should be evaluated first to determine the appropriate application and preparation requirements.
Yes. Spray foam can be used in many warehouse applications where improved insulation and air sealing are needed. It can help address large open areas, walls, ceilings, and other difficult-to-insulate spaces.
When professionally installed and properly maintained, spray foam is designed to provide long-lasting insulation and air-sealing performance. Its service life depends on installation quality and the conditions within the building.
The cost depends on factors such as the size of the building, areas being insulated, foam type, application thickness, accessibility, and overall project requirements. Contact Driftless Foam for a free estimate based on your commercial property.
