Why Choose Closed Cell Spray Foam?

Closed cell spray foam is the premium insulation choice for Alaska properties, offering superior thermal performance and multiple benefits in one application.

Superior R-Value

R-6.0 to R-7.0 per inch provides maximum thermal resistance

Air Sealing

Creates complete airtight seal eliminating drafts and air leaks

Moisture Barrier

Prevents moisture infiltration and condensation issues

Structural Support

Adds racking strength and structural integrity to buildings

Types of Spray Foam Insulation

Understanding the differences between closed cell and open cell spray foam is crucial for Alaska applications. We help you choose the right solution for your specific needs and climate conditions.

Closed Cell Spray Foam

2.0 lb Density
R-6.0-7.0
Per Inch
100%
Moisture Barrier

Our premium choice for Alaska's extreme climate. This high-density foam creates an impermeable barrier that serves as both insulation and moisture protection. Essential for exterior applications in Alaska's harsh conditions.

Key Features:

Superior thermal performance (R-6.0-7.0 per inch)
Complete air sealing and vapor barrier
Adds structural strength to buildings
Prevents ice dams and condensation
Resistant to water and moisture

Alaska Applications:

• Exterior walls and foundation walls
• Attics and roof decks
• Crawl spaces and basements
• Commercial buildings
• Any area requiring moisture protection

Open Cell Spray Foam

0.5 lb Density
R-3.5-4.0
Per Inch
Sound
Control

Lower-density foam with excellent sound dampening properties. Breathable and flexible, making it ideal for interior applications where sound control is the primary concern.

Key Features:

Excellent sound absorption properties
Breathable and flexible
Lower cost per square foot
Easier to trim and work with
Allows moisture vapor transmission
⚠️

Alaska Climate Limitation:

Not recommended for exterior walls in Alaska's climate due to moisture permeability and lower R-value.

• Limited interior applications only
• Sound control in interior walls
• Home theaters and music rooms
• Office partitions

Alaska Climate Recommendations

✅ Recommended: 2lb Closed Cell

Primary choice for Alaska homes due to extreme temperature fluctuations and moisture concerns.

• Superior performance in -40°F conditions
• Prevents ice dams and frost buildup
• Essential moisture protection
• Maximum energy efficiency
• Structural benefits in seismic zones

⚠️ Limited Use: 0.5lb Open Cell

Interior applications only where sound control is the primary goal.

• Not suitable for exterior walls
• Cannot withstand Alaska moisture
• Lower R-value inadequate for extreme cold
• Risk of condensation and mold
• Use only for soundproofing interiors

Professional Recommendation: For Alaska properties, we primarily install 2lb closed cell spray foam for thermal protection and structural integrity. Open cell foam is only used for specific interior sound control applications.

Vapor Barrier: The Critical Difference

Understanding vapor barrier performance is essential in Alaska's extreme climate. The difference between monolithic and piecemeal protection can make or break your insulation system.

2lb Closed Cell

Built-in Monolithic Vapor Barrier

2lb closed cell spray foam IS the vapor barrier. When properly applied, it creates a seamless, monolithic vapor barrier with no gaps, seams, or penetrations for moisture to exploit.

Monolithic Advantages:

Continuous Protection

No seams or joints for moisture infiltration

Self-Sealing Around Penetrations

Automatically seals around pipes, wires, and fasteners

Eliminates Installation Errors

No risk of missed spots or improper overlaps

Permanent Adhesion

Bonds directly to structure - won't sag or detach

Alaska Performance:

Perfect for Alaska's extreme temperature swings and high moisture loads. The monolithic barrier prevents the freeze-thaw cycling that can damage traditional vapor barriers.

0.5lb Open Cell

Requires External Vapor Barrier

Open cell foam is NOT a vapor barrier. It requires a separate plastic vapor barrier that must be perfectly installed with no gaps or penetrations.

Installation Challenges:

Seam Integrity Issues

Every seam and overlap is a potential failure point

Penetration Problems

Difficult to seal around pipes, wires, and outlets

Installation Errors

Human error can compromise entire system

Durability Concerns

Plastic barriers can tear, sag, or detach over time

⚠️ Alaska Climate Risk:

In Alaska's extreme conditions, any gap in the vapor barrier can lead to catastrophic moisture problems, ice dams, mold growth, and structural damage. The risk is too high for exterior applications.

Professional Perspective: Why Monolithic Matters

The Monolithic Advantage

In Alaska's challenging climate, moisture control is not just important—it's critical for structural integrity and occupant health.

"We've seen too many failures with piecemeal vapor barriers. Even the smallest gap can lead to thousands of dollars in damage. That's why we recommend 2lb closed cell foam for all exterior applications in Alaska."

Real-World Performance

• 15+ years of proven performance in Alaska conditions
• Zero callback issues related to moisture infiltration
• Eliminates the most common source of insulation failure
• Provides peace of mind for homeowners and contractors
• Meets or exceeds all Alaska building code requirements

Bottom Line: While open cell foam may cost less initially, the risks and potential costs of moisture-related failures in Alaska make 2lb closed cell foam the only responsible choice for exterior applications.
