Benefits of Commercial Spray Foam Insulation
Lower Energy Costs
Seals air leaks and provides superior insulation, reducing heating and cooling expenses year-round.
Consistent Indoor Comfort
Eliminates drafts and hot/cold spots, creating a stable environment for employees, customers, and tenants.
Noise Reduction
Creates an airtight barrier that prevents moisture intrusion, lowering the risk of mold growth and building damage.
Moisture & Mold Control
Reduces emissions by replacing fossil-fuel systems, especially when powered by renewable electricity.
Longer Building Lifespan
Strengthens walls, roofs, and structures by adding rigidity, protecting your investment for the long term.
Improved Indoor Air Quality
Reduces entry of dust, pollen, and pollutants, promoting a healthier workspace.
Choosing the Right Spray Foam for Your Commercial Building
Both open-cell and closed-cell spray foam deliver excellent insulation, but each is suited to different needs. Understanding the differences helps you choose the best option for your building’s performance and budget.
Open Cell Spray Foam
- Cost-effective for interior walls and ceilings
- Expands to seal gaps and irregular cavities
- Strong sound absorption with drying potential
- Lightweight and easy to trim around MEPs
Closed Cell Spray Foam
- High R-value per inch with air and vapor control
- Adds rigidity to walls and roof decks
- Durable and moisture resistant for tough environments
- Helps control condensation on metal skins

Types of Spray Foam Insulation
Open-Cell Spray Foam for Commercial Buildings
Open-cell spray foam is lightweight and flexible, expanding significantly to fill cavities and provide excellent sound absorption.
Its open-bubble structure allows limited air and moisture movement, making it best for interior use in conditioned spaces.️
Lightweight & Expansive: Fills gaps and cavities effectively.️
Sound Absorption:Reduces noise transfer between offices and interior spaces.️
Cost-Efficient: More affordable for large interior areas.️
Best For: Interior walls, ceilings, and partitions in offices, retail, schools, and other conditioned spaces.

Closed Cell Spray Foam
Closed-cell spray foam is dense and rigid, creating a strong, moisture-resistant barrier with a higher R-value per inch.
It also reinforces the structure, making it ideal for exterior applications and demanding environments.️
High Insulation Value: Offers superior R-value per inch for energy efficiency.️
Moisture & Vapor Barrier:Protects walls, roofs, and other exposed areas.️
Adds Structural Strength: Reinforces walls and roofs in large buildings.️
Best For: Exterior walls, flat or sloped roofs, warehouses, industrial spaces, and cold storage facilities.
