Closed Cell Spray Foam Insulation Installation
High-Performance Closed Cell Spray Foam
Closed cell spray foam insulation is one of the most durable and energy-efficient insulation solutions available today. At East Coast Insulation, we specialize in professional insulation installation for both residential and commercial properties.
This type of spray foam creates a dense, rigid insulation barrier that helps reduce air leakage, improve structural strength, and protect against moisture intrusion. Because of its capabilities to increase structural integrity of the building, and its air-sealing capabilities, it is often used in areas where maximum insulation performance is required.
Whether you are insulating a new building, upgrading an attic or crawl space, or simply improving the efficiency of a structure, this will provide long-lasting results.
What is Closed Cell Spray Foam Insulation?
Closed cell spray foam is a rigid foam insulation material that expands when applied and cures into a dense protective layer. The foam’s tightly packed cell structure creates a strong barrier against air, moisture, and heat transfer.
This type of insulation is commonly installed in:
Crawl Spaces
Exterior Walls
Metal Buildings
Attics & Roof Decks

Benefits of Closed Cell Spray Foam Insulation
Higher R-Value Per Inch
Closed cell spray foam provides one of the highest insulation values available, helping maximize thermal performance even in tight spaces.
.
Superior Moisture Resistance
The dense structure of closed cell foam helps prevent water intrusion and reduces the risk of moisture-related damage.
.
Improved Structural Strength
Closed cell foam adds rigidity to walls and roofing systems, which can enhance the overall durability of the structure.
.
Air Sealing Performance
By expanding during installation, spray foam fills small cracks and seams that allow air leakage in traditional insulation systems.
.
Long-Lasting Insulation
This type of insulation does not sag, settle, or deteriorate over time, providing consistent insulation performance for many years.

FAQ: Closed Cell Spray Foam Insulation
What is the difference between open cell and closed cell spray foam?
This foam is denser and provides a higher R-value per inch compared to open cell foam. It also offers greater moisture resistance and structural strength.
Is closed cell spray foam waterproof?
Yes, it is highly resistant to moisture and water intrusion, making it a good option for crawl spaces, basements, and other areas where moisture may be present.
How long does closed cell spray foam insulation last?
When properly installed, this spray foam can last for decades without settling, sagging, or losing its insulating properties.
Does closed cell spray foam increase energy efficiency?
Yes, because it creates a thermal barrier, a moisture barrier, and an air barrier, closed cell foam can significantly reducing those energy losses as a result.
Can closed cell spray foam strengthen a building?
Yes. Closed cell foam can add structural rigidity to certain building components, which may improve overall durability.
Where is closed cell spray foam typically used?
Closed cell spray foam is often used in crawl spaces and metal buildings where high insulation performance, and particularly a moisture barrier is needed.
