Spray foam insulation improves temperature control, reduces energy loss, and strengthens the structural integrity of agricultural buildings. In high-humidity or temperature-variable environments like barns or storage sheds, spray foam creates an airtight barrier that prevents mold growth and pest infiltration, while enhancing the performance of HVAC systems and refrigeration units.
Its ability to conform to irregular surfaces and seal gaps in older or unsealed structures makes it more effective than traditional insulation methods. Spray foam reduces the workload of heating and cooling systems, prolongs equipment lifespan, and cuts operating costs.
Ohio Valley Spray Foam applies these solutions using experience with rural buildings and metal structures across the Ohio Valley region, where fluctuating temperatures and humidity demand durable insulation systems.
Spray foam is applied as a liquid and expands rapidly, creating a seamless insulation layer. This minimizes air leakage and delivers consistent R-values in barns, livestock shelters, equipment garages, and crop storage facilities.
Key practical impacts include:
| Feature | Spray Foam (Closed Cell) | Spray Foam (Open Cell) | Blown-In Fiberglass | Batt Insulation |
|---|---|---|---|---|
| Air Seal | Yes | Partial | No | No |
| Moisture Barrier | Yes | No | No | No |
| R-Value per Inch | 6.0 – 7.0 | 3.5 – 4.0 | 2.2 – 2.7 | 3.1 – 3.4 |
| Adherence to Surfaces | Excellent | Excellent | Poor | Moderate |
| Mold Resistance | High | Medium | Low | Low |
| Structural Support | Adds rigidity | Minimal | None | None |
| Installation Time (avg barn) | 1 day | 1 day | 2-3 days | 2 days |
| Type of Foam | R-Value/inch | Application Density | Best For | Expansion Rate |
|---|---|---|---|---|
| Closed-Cell Spray | 6.5 – 7.0 | 2.0 lbs/ft^3 | Exterior walls, metal roofs | Low |
| Open-Cell Spray | 3.6 – 4.0 | 0.5 lbs/ft^3 | Interior walls, ceiling voids | High |
In Ohio Valley’s humid summers and cold winters, closed-cell foam resists condensation that causes rust on metal frames and siding.
Local temperature shifts often lead to condensation inside uninsulated barns, especially during seasonal transitions. Spray foam eliminates thermal bridging, where internal heat meets cold steel, creating moisture. This protects:
Spray foam insulation also reduces the chances of frozen water lines and provides a more stable environment for livestock.
Use closed-cell foam under metal roofing to quiet rain and reduce temperature spikes that stress livestock.
Once cured, spray foam is inert. Ensure proper ventilation during and shortly after installation.
It can, but loose or degraded insulation should be removed for best results.
It deters pests by sealing entry points, but it isn’t a rodent repellent.
Spray foam can last 30+ years without losing insulation value if properly applied.

Inspect annually for damage or moisture intrusion. Repairs are typically minimal if installed correctly.
Yes, hybrid systems are sometimes used—such as spray foam for air sealing plus fiberglass for added bulk R-value.
Surfaces should be clean and dry. Some metal may need priming for better foam adherence.
Peeling, water stains, or soft spots indicate compromised sections that may need resealing.
Improved air sealing may require mechanical ventilation upgrades to maintain air quality.
