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.
Westby sits high in the coulee country of Vernon County, where ridgelines channel cold winter winds and valleys trap moisture throughout the shoulder seasons. This terrain-driven climate is hard on buildings. Homes and farm structures in the Westby area face persistent infiltration from wind-driven cold air in winter and heavy humidity in late summer — and traditional insulation products were simply not designed to handle both.
Many Westby homes and agricultural buildings still carry the original insulation installed when they were built — fiberglass batts and blown products that have been compressing and losing performance for years. They don't air-seal. They absorb moisture. In the coulee hills of Vernon County, that means your building is working against you from the inside out. The costs are real and they compound every season:
Heating bills that spike sharply from November through March
Cold drafts along exterior walls, floors, and around windows
Pole barns and dairy facilities fighting frost and condensation all winterctural integrity
Moisture trapped inside wall cavities causing mold and rot over time
Uncomfortable temperature swings from the ground floor to the upper level
Westby's elevated geography and coulee climate demand insulation that performs all the way to the edges — no gaps, no voids, no settling. Driftless Foam's spray foam expands on contact and bonds permanently to your structure, creating a continuous thermal and air barrier that traditional insulation can never replicate.
Moisture control and full air sealing for shops, barns, equipment storage buildings, and farm structures across the region.


Warehouses, retail spaces, offices, and industrial buildings requiring high-performance insulation for year-round operational efficiency.

Attics, walls, crawl spaces, basements, garages, and new construction homes — comprehensive coverage for every area of your home.

2-pound closed-cell spray foam for superior air sealing, vapor control, moisture resistance, and added structural strength.

We assess your building, insulation needs, and long-term goals to determine whether closed-cell or open-cell spray foam is the right fit for your specific structure and climate.
Our trained team installs the correct spray foam solution with care, proper thickness, and professional-grade equipment to ensure full coverage and lasting performance.
You experience improved indoor comfort, lower utility bills, better moisture control, and a stronger building envelope for years to come.
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.
