Spray Foam Done Right = Better Performance
Spray foam insulation—both open-cell and closed-cell—offers industry-leading thermal performance and air sealing compared with traditional insulation. But the key to mold-free performance? Proper installation, moisture control, and HVAC planning.
Open-Cell Spray Foam
✔️ Great air sealing
✔️ Fills hard-to-reach areas
✔️ Excellent sound control
✔️ Budget-friendly
⚠️ Because it’s semi-permeable, it doesn’t act as a v***r barrier on its own—so moisture pathways must be managed properly.
Closed-Cell Spray Foam
✔️ Higher insulation value per inch (better R-value)
✔️ Acts as an air AND v***r barrier
✔️ Resists water and moisture absorption
✔️ Adds rigidity and structural strength
Ideal for metal buildings, roofs, and areas prone to moisture.
🌧️ About Mold Concerns
Spray foam itself doesn’t feed mold—it’s synthetic, not organic. Mold only grows where there’s moisture and organic material to feed on.
Most mold issues attributed to spray foam are actually caused by:
• Moisture trapped from poor roof or wall details
• Spray foam installed over wet surfaces
• Lack of proper v***r barrier or ventilation
• HVAC not balanced to control humidity levels
✅ The bottom line: When installed correctly—with the right product, moisture control strategy, and airflow management—spray foam delivers superior comfort, energy efficiency, and mold resistance. Professional installers ensure proper coverage, thickness, and building-science best practices every time.
