Spray Foam Insulation

Spray Foam Insulation

Spray foam insulation is a high performance insulation and air barrier system that provides superior thermal resistance and energy efficiency. Unlike traditional insulation materials, spray foam expands to fill cavities, cracks, and gaps, creating a seamless envelope that significantly reduces air leakage.

Structo Insulation specializes in the application of both open cell and closed cell spray foam, ensuring that the right product is selected for your specific building requirements.

Why Choose Spray Foam Insulation

Superior air sealing
Air leakage is a primary cause of energy loss in buildings. Spray foam seals the building envelope, preventing conditioned air from escaping and outdoor air from entering.

High thermal resistance
Spray foam offers a high R value per inch, providing excellent insulation power even in limited spaces.

Moisture management
Closed cell spray foam acts as a vapor retarder and resists bulk water, helping to protect the structure from moisture damage.

Structural reinforcement
Closed cell foam adds rigidity to walls and roof assemblies, increasing the overall structural strength of the building.

How Spray Foam Works

Spray foam is applied as a liquid that reacts and expands within seconds to fill the space where it is sprayed. This expansion allows it to conform to irregular shapes, seal around penetrations (such as pipes and wires), and bond securely to the substrate.

The result is a continuous, monolithic insulation layer that eliminates the gaps and compression issues often associated with fiberglass or cellulose insulation.

Open Cell vs Closed Cell Insulation

Open Cell Spray Foam

• Lighter density and softer texture
• Expands significantly to fill large cavities
• Excellent sound absorption qualities
• Typically used for interior walls and roof decks
• Lower cost per board foot compared to closed cell

Closed Cell Spray Foam

• High density and rigid texture
• High R value per inch (approx R 6 to R 7)
• Acts as a vapor retarder and resists water absorption
• Adds structural strength to the building
• Ideal for exterior walls, crawl spaces, and metal buildings

Is Spray Foam the Right Choice for Your Project

Spray foam is a powerful insulation solution, but it must be applied correctly and in the appropriate locations. Factors such as building type, climate zone, and budget play a role in determining whether spray foam is the best fit.

Structo Insulation evaluates your project to recommend the most effective spray foam system, ensuring proper application and long term performance.
