Closed Cell Spray Foam Application

Closed cell spray foam is a high-performance insulation material applied as a liquid that quickly expands to form a dense, rigid barrier. It provides superior thermal resistance, air sealing, and moisture control. Ideal for walls, roofs, and crawl spaces, closed cell spray foam enhances energy efficiency, improves structural integrity, and helps prevent mold and mildew growth.

It is commonly used in both residential and commercial applications where durability and high insulation value are required. R-value: Closed-cell foam has one of the highest R-values (R-6.9 to R-7.5 per inch), offering better thermal resistance than most other insulation materials.Approximate Cost: The cost of closed-cell spray foam insulation typically ranges from $1.50 to $2.50 per board foot, depending on factors like location, thickness required, and the size of the project.

Places for Application

  • Exterior Walls
  • Roofs
  • Crawlspace
  • Fundation
  • Patios
  • Concrete Walls
  • Warehouses
  • Commercial and Industrial Buildings
  • Metal Buildings

Advantages

  • Thermal Resistance: Closed cell foam offers a high R-value per inch, making it highly effective at minimizing heat transfer, which improves energy efficiency and maintains comfortable indoor temperatures.
  • Air Sealing: Closed cell foam creates a tight seal, minimizing air leaks that can bring in moisture, and avoid air leakage from home to save energy.
  • Water Resistance: It is dense and rigid, providing a barrier that resists water penetration, reducing the chances of mold or mildew growth.
  • Vapor Barrier: Closed cell spray foam can act as a vapor barrier, reducing the risk of condensation inside walls and other cavities.

Benefits/Results after Application

Better Temperature Control

Application Process

  • The foam is sprayed onto the surface.
  • It expands to fill cavities and small gaps.
  • Once applied, it hardens in place, forming an air seal and thermal barrier blanket.

Expectations while application process:

01
Noise and Odor

Equipment will produce noise, and there might be some odors during application, but these dissipate quickly.

02
Ventilation

The area will need to be well-ventilated during and after application.

03
Temporary Displacement

You may need to vacate the area being insulated for a few hours to allow the foam to set and cure.

Cost Effective

Soundproofing
Excellent due to open-cell structure

Good option, not design for sound proofing

Vapor Barrier
No, allows moisture to pass through

Yes, acts as a vapor barrier

Strength
Flexible, not as rigid

Rigid, adds structural strength

Best Use
Interior walls, attics, soundproofing, not in places with moisture is present

Exterior walls, roofs,underfloors, basements and areas with high moisture ris
