Home upgrades
Spray foam is a strong fit for remodels, additions, garages, bonus rooms, new construction, and hard-to-condition spaces. Open-cell foam is often selected for cavity filling and sound control.

Spray Foam Insulation in San Antonio, TX
If your home, shop, attic, or commercial building in San Antonio, TX struggles with heat, drafts, humidity, or high energy bills, spray foam insulation can make the building envelope work harder. 111 Roofing & Exteriors installs spray foam insulation for residential and commercial properties across San Antonio and nearby communities.
Air sealing and insulation
Spray foam contractors serving San Antonio homes, shops and commercial buildings.
Texas buildings deal with long cooling seasons, hot roof decks, mixed humidity, and sudden weather shifts. Fiberglass and loose-fill insulation can help with R-value, but they do not seal air movement the way spray polyurethane foam does. Spray foam expands into gaps, cracks, and hard-to-reach cavities, creating an insulation and air-sealing layer in one application.
Hot summers, attic retrofits, garages, military-area housing, and commercial buildings make San Antonio projects especially dependent on thermal control.
For San Antonio property owners, the right recommendation depends on the building type, access, existing insulation, ventilation approach, moisture exposure, and whether the goal is comfort, condensation control, sound reduction, or better commercial energy performance.

Residential insulation
Attic spray foam insulation in San Antonio.
Attics are one of the most common places for comfort problems in San Antonio homes. Hot upstairs rooms, long HVAC run times, dusty air movement, and uneven temperatures often trace back to attic air leakage. Spray foam can be applied to the roof deck or selected attic areas depending on the structure, ventilation approach, and project goals.
Closed-cell foam
Closed-cell spray foam is commonly used where added rigidity, moisture resistance, and higher R-value per inch are needed, especially in metal buildings and selected exterior assemblies.
Comfort planning
Before installation, the project should account for ventilation, combustion appliances, indoor air quality, roof condition, moisture paths, and how the HVAC system serves the space.
Commercial and metal buildings
Commercial spray foam insulation in San Antonio.
111 Roofing & Exteriors installs spray foam insulation for commercial and industrial properties in San Antonio, including offices, warehouses, retail spaces, metal buildings, workshops, and storage facilities. Spray foam helps reduce uncontrolled air movement and can support more stable interior temperatures in buildings with large rooflines, metal panels, or exposed framing.
Metal buildings in Texas can collect heat quickly and are prone to condensation when the assembly is not designed well. Closed-cell spray foam is often used on metal panels because it bonds to the surface, helps control condensation, and adds insulation without leaving gaps around framing members.
- 01
Review the building
Identify the roof deck, wall panels, framing, existing insulation, air leaks, moisture risks, access, and occupied areas before choosing the foam type.
- 02
Select open or closed cell
Open-cell and closed-cell foam perform differently. The right choice depends on location, moisture exposure, R-value goals, budget, and building use.
- 03
Prepare the work area
Surfaces should be dry, clean, accessible, and protected. Commercial projects may also require scheduling around tenants, inventory, equipment, or production.
- 04
Confirm the quote scope
A good proposal identifies the application area, approximate thickness, foam type, access assumptions, exclusions, and any follow-up coating or ventilation needs.
Benefits for San Antonio
Why property owners choose spray foam insulation.
Less air leakage
Spray foam helps close cracks, penetrations and framing gaps that allow hot attic air, dust and humid outdoor air to move through the building.
Better attic comfort
Rooms affected by attic heat may feel more consistent when the building envelope is properly sealed and insulated.
Lower HVAC strain
Reducing uncontrolled heat transfer may help heating and cooling equipment work less aggressively during hot Texas weather.
Irregular spaces
Foam can fill difficult cavities, metal building ribs, shop walls, garages and framing areas where batts are hard to fit cleanly.

San Antonio spray foam FAQ
Common questions before requesting a quote.

What type of spray foam is best in San Antonio?
The best foam depends on the building. Open-cell foam is often used for interior cavities and sound control, while closed-cell foam is often chosen for metal buildings, moisture-sensitive areas, and projects that need higher R-value per inch. 111 Roofing & Exteriors can recommend the right option after reviewing the structure.
Can spray foam help lower energy bills in San Antonio?
Spray foam may reduce heating and cooling waste by sealing air leaks and slowing heat transfer. Actual savings depend on the building, HVAC system, existing insulation, and installation area.
Do you install spray foam insulation in metal buildings in San Antonio?
Yes. 111 Roofing & Exteriors installs spray foam insulation in metal buildings, shops, warehouses, garages, and barndominiums in San Antonio. Closed-cell foam is commonly used on metal panels because it can help control condensation and improve thermal performance.
