Key Features:

• Exceptional R-Value: Closed cell spray foam offers an impressive R-value of around 6.5 to 7.0 per inch, making it one of the most efficient insulation materials available. This means better energy savings and a more comfortable indoor environment.
• Moisture Resistance: Its dense structure acts as a formidable moisture barrier, preventing water infiltration and helping to reduce the risk of mold and mildew growth, particularly in basements and crawl spaces.
• Structural Integrity: The rigidity of closed cell foam enhances the strength of walls and roofs, providing additional support and improving overall building durability.
• Air Sealing: This insulation creates a tight seal that minimizes air leaks, helping to eliminate drafts and enhance energy efficiency.

Ideal Applications:

Closed cell spray foam is perfect for a variety of applications, including:

• Roofs: Providing insulation and protection against the elements.
• Walls: Ideal for both interior and exterior walls, especially in climates with high humidity.
• Basements and Crawl Spaces: Effective in controlling moisture and enhancing comfort in lower levels of a building.

Considerations:

• Higher Initial Investment: Closed cell spray foam insulation typically has a higher upfront cost compared to traditional insulation materials like loose fill or fiberglass roll. However, its energy savings can offset this over time.
• Professional Installation Required: Proper application is crucial for effectiveness. Hiring experienced professionals is recommended, as incorrect installation can lead to air leaks and reduced performance.
• Equipment and Safety: Installation requires specialized equipment and safety precautions, including personal protective gear.
• High Thermal Resistance: Closed cell foam has a high R-value (around 6.5 to 7.0 per inch), making it very effective in reducing energy costs. Ensure you choose the right thickness for optimal performance.
• Moisture Barrier: Closed cell foam is impermeable to moisture, which is beneficial in preventing mold growth. However, in some cases, a vapor barrier may still be required depending on local building codes and climate conditions.
• Limited Breathability: Because it is not vapor-permeable, closed cell foam can trap moisture in certain environments. Proper ventilation is important to avoid potential issues.
• Flammability: Closed cell spray foam is flammable and should be covered with a fire-rated material in living spaces to comply with building codes. Consult local regulations for safety requirements.
• Chemical Components: The foam contains chemicals that can have environmental impacts. Look for manufacturers that offer eco-friendly formulations with lower global warming potential (GWP).
• Durability: Closed cell spray foam is durable and can last for many years without significant degradation. However, ensure that it is applied correctly to maintain its effectiveness.
• Regulations and Permits: Check local building codes and regulations to ensure compliance with installation requirements and to determine if permits are necessary.
