Spray Foam Insulation Services in San Antonio

At Geo Insulation, we specialize in providing top-quality spray foam insulation services to homeowners and businesses in San Antonio. Our goal is to enhance your property’s energy efficiency, comfort, and overall value.

What Is Spray Foam?

Spray foam insulation is a modern solution that involves applying a liquid foam, which expands and hardens into a solid layer. This method effectively seals gaps, cracks, and hard-to-reach areas, creating an airtight barrier that traditional insulation materials often can’t achieve.

The Geo Insulation Advantage

Benefits of Insulating Your Home

  • Energy Efficiency: Spray foam significantly reduces energy loss by creating a tight seal, leading to lower heating and cooling costs. This is especially beneficial in San Antonio’s hot climate, where maintaining indoor temperatures can be challenging.
  • Improved Indoor Air Quality: By sealing cracks and crevices, spray foam insulation minimizes the infiltration of pollutants, allergens, and moisture, contributing to a healthier indoor environment.
  • Enhanced Comfort: Maintaining consistent indoor temperatures becomes easier with spray foam insulation, eliminating hot or cold spots within your property.
  • Structural Integrity: The rigidity of spray foam adds strength to walls and ceilings, enhancing the overall structural integrity of your building.
  • Moisture Barrier: Spray foam acts as a barrier against moisture, reducing the risk of mold and mildew growth, which is crucial in humid environments like San Antonio.

Types of Spray Foam

There are two main types of insulation available:

  • Open-Cell Spray Foam: This type is less dense, providing excellent air sealing and soundproofing qualities. It’s typically used for interior applications.
  • Closed-Cell Spray Foam: Denser and more rigid, closed-cell foam offers higher insulation values and acts as a vapor barrier, making it suitable for both interior and exterior applications.

Frequently Asked Questions About Spray Foam Insulation

Our team begins by preparing the space. We cover floors, windows, and any areas that don’t require insulation. The foam is then sprayed into cavities, where it expands to fill every gap and crack. Depending on the size of the job, most projects are completed in a single day.

Yes. Once cured, spray foam is non-toxic, does not emit harmful fumes, and is safe for people and pets. Installation should always be handled by trained professionals to ensure proper application and ventilation during the curing process.

Spray foam doesn’t sag, settle, or degrade the way fiberglass or cellulose can. With proper installation, it can last 20+ years. The spray foam often matches the lifespan of the structure itself.

Most homeowners save between 15–40% on heating and cooling costs. Because spray foam seals air leaks as well as insulating, it reduces the load on your HVAC system, which also extends its lifespan.

Spray foam offers higher R-values per inch and provides an air barrier that fiberglass cannot. While the upfront cost is higher, spray foam delivers better performance, durability, and long-term savings.

Common areas include attics, crawl spaces, basements, rim joists, walls, and around plumbing or ductwork. It’s especially effective in spaces where air leakage is a problem.
