What is Spray Foam Insulation?
Spray foam insulation is a cutting-edge insulation solution that expands to fill gaps, cracks, and
cavities in your home. Unlike traditional insulation materials like fiberglass or cellulose, spray foam
creates an airtight seal that dramatically improves your home's energy efficiency.

Open Cell vs Closed Cell Spray Foam: The Key Differences
Understanding the difference between open cell and closed cell spray foam is crucial for making the right
choice for your home. Here's what sets them apart:
Open Cell Spray Foam Insulation
What is Open Cell Foam?
Open cell spray foam has a porous, "open" cell structure that allows air and moisture to pass through.
This makes it lighter and more flexible than its closed cell counterpart.
Key Characteristics:
- Density: 0.5 lbs/ft³
- R-Value: 3.5-4.0 per inch
- Cost: 30-50% less expensive than closed cell
- Moisture Permeability: Allows vapor transmission
- Sound Absorption: Excellent acoustic properties
Best Applications for Open Cell:
- Interior walls for soundproofing
- Attics in moderate climates
- Areas where budget is a primary concern
- Sound control between floors
Closed Cell Spray Foam Insulation
What is Closed Cell Foam?
Closed cell spray foam has a dense, rigid structure where cells are completely closed off. This creates a
superior moisture barrier and higher insulation value.
Key Characteristics:
- Density: 2.0 lbs/ft³
- R-Value: 6.0-7.0 per inch
- Moisture Barrier: Acts as vapor barrier
- Structural Strength: Adds rigidity to buildings
- Water Resistance: Unaffected by water damage
Best Applications for Closed Cell:
- Basement walls and foundations
- Exterior walls in harsh climates
- Areas prone to moisture
- Applications requiring structural support

Cost Comparison: Open Cell vs Closed Cell
One of the biggest factors in choosing spray foam insulation is cost. Here's the breakdown:
Open Cell Spray Foam Cost
- Material Cost: $0.35-$0.55 per board foot
- Installation Cost: $1.50-$3.50 per square foot
- Total Project Savings: 30-50% less than closed cell
Closed Cell Spray Foam Cost
- Material Cost: $1.00-$1.50 per board foot
- Installation Cost: $3.00-$7.00 per square foot
- Long-term Value: Higher upfront cost, better long-term performance

Performance Comparison: Which Performs Better?
R-Value Performance
- Closed Cell Wins: 6.0-7.0 R-value per inch vs 3.5-4.0 for open cell
- Space Efficiency: Need less thickness with closed cell for same insulation value
- Climate Considerations: Closed cell better for extreme climates
Moisture Control
- Closed Cell: Complete moisture barrier, prevents mold and mildew
- Open Cell: Allows moisture transmission, requires proper vapor barrier
- Flood Risk: Closed cell unaffected by water damage
Air Sealing
- Both Excellent: Both types create superior air sealing compared to traditional insulation
- Energy Savings: Both can reduce energy bills by 20-40%
When to Choose Open Cell Spray Foam
Choose open cell spray foam when:
✅ Budget is a primary concern
✅ Soundproofing is important (interior walls, between floors)
✅ Moderate climate conditions
✅ Interior applications where moisture isn't a concern
✅ Large areas where cost savings matter most
Perfect for: Attics in dry climates, interior sound control, budget-conscious projects
When to Choose Closed Cell Spray Foam
Choose closed cell spray foam when:
✅ Maximum insulation performance needed
✅ Moisture control is critical (basements, crawl spaces)
✅ Harsh climate conditions (extreme hot or cold)
✅ Structural support is beneficial
✅ Long-term investment priorities
Perfect for: Basements, exterior walls, flood-prone areas, extreme climates

Energy Savings: Open Cell vs Closed Cell
Both types of spray foam deliver significant energy savings, but in different ways:
Open Cell Energy Benefits
- Air Sealing: Eliminates drafts and air leaks
- Cost-Effective Coverage: Cover more area for less money
- ROI Timeline: Faster payback due to lower upfront cost
Closed Cell Energy Benefits
- Superior R-Value: Maximum thermal performance per inch
- Moisture Prevention: Eliminates energy loss from moisture issues
- Long-term Performance: Maintains efficiency longer
Average Energy Savings: Both types typically reduce heating and cooling costs by 20-40%
Installation Considerations
Professional Installation Required
Both open and closed cell spray foam require professional installation for optimal performance:
- Proper mixing ratios
- Correct application temperatures
- Safety equipment and ventilation
- Quality control and inspection
Installation Timeline
- Open Cell: Faster application, quicker cure time
- Closed Cell: Slower application, requires more precision

Common Myths About Spray Foam Insulation
Myth 1: "Spray foam is too expensive"
Reality: While upfront costs are higher, energy savings often pay for the investment within 2-5 years.
Myth 2: "One type is always better"
Reality: The best choice depends on your specific application, climate, and budget.
Myth 3: "DIY spray foam is just as good"
Reality: Professional installation ensures proper mixing, application, and safety.
Environmental Impact: Which is Greener?
Open Cell Environmental Benefits
- Lower material usage per R-value in thick applications
- Reduced transportation costs due to lower density
- Renewable content options available
Closed Cell Environmental Benefits
- Higher efficiency means less energy consumption long-term
- Longer lifespan reduces replacement needs
- Moisture prevention prevents mold and material degradation
Making Your Decision: Open Cell vs Closed Cell
Consider these factors when making your choice:
1. Climate Zone: Harsh climates favor closed cell
2. Application Area: Basements and exteriors need closed cell
3. Budget Constraints: Open cell offers better initial value
4. Moisture Concerns: High moisture areas require closed cell
5. Performance Priority: Maximum R-value = closed cell
Frequently Asked Questions
Can I mix open and closed cell in the same home?
Yes! Many homeowners use closed cell in basements and exterior walls, and open cell in attics and
interior walls for optimal cost-performance.
How long does spray foam last?
Both types can last 20+ years when properly installed, with closed cell typically lasting longer.
Is spray foam safe after installation?
Yes, once properly cured (24-48 hours), both types are safe for occupied spaces.
