Spray foam insulation offers consistent thermal control, air sealing, and moisture resistance across expansive structures. For large industrial facilities, these benefits translate into lower operational costs, reduced energy waste, and greater durability in challenging environments.
The uniform application of spray foam across metal panels, concrete, and roof substrates eliminates air gaps that commonly occur with batt or board insulation. It performs reliably in extreme temperatures, making it suitable for warehouses, plants, and processing centers across Illinois and other climate-variant regions.
South Chicago Insulation provides this technical evaluation based on direct field experience in applying spray foam systems across diverse commercial and industrial projects, including retrofits and high-performance roof systems.
Spray foam expands to conform to irregular shapes, joints, and voids common in large facilities. This ensures continuous insulation coverage, reducing thermal bridging and leakage.
| Insulation Type | R-Value per Inch | Air Barrier | Moisture Barrier | Seamless Application | Suited for Large Areas |
|---|---|---|---|---|---|
| Closed-Cell Spray Foam | 6.0 – 7.5 | Yes | Yes | Yes | Excellent |
| Open-Cell Spray Foam | 3.5 – 4.0 | Yes | Partial | Yes | Moderate |
| Fiberglass Batts | 2.9 – 3.8 | No | No | No | Poor |
| Rigid Foam Board | 4.5 – 6.5 | Partial | Partial | No | Moderate |
Bonus Tip: Use closed-cell spray foam in facilities with large bay doors or poor sealing around loading docks. It maintains envelope integrity even under negative pressure.
According to the U.S. Department of Energy, up to 30% of heating and cooling energy is lost through air leakage in non-insulated or poorly insulated commercial buildings (source). Spray foam’s airtight seal directly reduces this waste.
| Factor | Spray Foam | Fiberglass | Rigid Board |
|---|---|---|---|
| Installation Time | Moderate | Fast | Moderate |
| Labor Cost | Medium | Low | Medium |
| Lifespan | 25-35 years | 10-15 years | 20-30 years |
| Maintenance Frequency | Low | High | Medium |
| Overall Energy Savings | High | Low | Moderate |
Bonus Tip: Facilities with automated systems or sensitive equipment benefit from the humidity resistance of closed-cell foam, which helps prevent condensation-related failures.
| Property | Value |
|---|---|
| Nominal Density | 2.0 lbs/ft³ |
| Compressive Strength | 20-30 psi |
| Water Absorption (ASTM D2842) | < 0.03% |
| R-Value (per inch) | 6.0 – 7.5 |
| Flame Spread Index (ASTM E84) | < 25 |
| VOC Emissions (EPA Method 24) | Low |
Spray foam insulation maintains performance during freeze-thaw cycles common in northern Illinois winters. Its ability to form a vapor barrier is beneficial in humid summer months, reducing mold risks in facilities storing moisture-sensitive goods.
Bonus Tip: For facilities near Lake Michigan, use intumescent coatings over spray foam to meet code-mandated fire ratings without compromising R-value.
Yes. Both open-cell and closed-cell foam offer some level of acoustic dampening, especially in metal or concrete structures.
Initial curing occurs within minutes, but full curing and off-gassing may take 24-48 hours depending on temperature and humidity.
Yes. It adheres well to clean, dry metal surfaces with proper surface prep.
Spray foam does not serve as a food source and creates barriers that discourage nesting.

Closed-cell spray foam is generally more suitable due to its high R-value, strength, and moisture resistance.
Yes, when paired with intumescent or thermal barriers as specified by code.
No. Once cured, removal requires mechanical scraping or demolition. Decisions should be long-term.
Improved airtightness may reduce HVAC load requirements. Mechanical engineers should reassess system sizing post-installation.
It retains its properties for decades if protected from prolonged UV exposure and physical damage.
