Spray Foam is a Top Choice for San Antonio Insulation. Properly insulating your home or building helps to maintain comfortable temperatures year-round.  No matter what kind of insulation you currently have in your attic, you can quickly determine if you need more by looking across the span of your attic. If your insulation is just level with or below your floor joists (i.e., you can easily see your joists), you should add more. It is important that the insulation be evenly distributed, as sometimes there is enough insulation in the middle of the attic but very little along the eaves.

Insulation levels are specified by R-Value, which is a measure of the insulation’s ability to resist heat flow. The higher the R-Value, the better the thermal performance of the insulation. The recommended level for most attics is to insulate to R-38 or about 12 to 14 inches, depending on your insulation type.

Geo-Insulation offers a variety of services for residential and commercial customers to help increase energy efficiency


Liquid foam insulation materials can be sprayed, foamed-in-place, injected, or poured to fill very small cavities, giving them twice the R-value per inch than traditional batt insulation. Foam materials now have foaming agents that don’t use the chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs) that are harmful to the ozone layer. Foam insulation in crawl spaces and other areas helps prevent air leaks and reduces energy bills.


Various types of insulation are available made from fiberglass, each with its own advantages. Fiberglass Insulation which is available in batts and rolls, is used in areas where there are large open spaces, such as cathedral ceilings.


Loose Fill Blown-In Insulation is made from recycled materials, and  it is blown into the attic or other areas by machine and can conform to any space, making it ideal for locations that are hard to reach or irregularly shaped. Loose Fill Insulatio can reduce your heating and cooling bill by up to 35%.
