Geo-Insulation offers various types of fiberglass insulation for commercial and residential customers.  Understanding insulation is key to knowing what type of insulation is best for your needs. 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 R-38 or about 13 to 14 inches of insulation.  We recommend R-50 or about 19 inches of insulation for a two story home.

CPS Energy presently offers an energy rebate program to help offset the cost of adding insulation to your attic floor or foam insulation on the attic roof decking. For additional information please contact Tom Porter, (210) 848-5658 or visit the CPS Energy rebate program website.

The Difference Between Fiberglass Loose Fill Insulation and Fiberglass Insulation in Batts and Rolls


Available in batts and rolls, with a depth of 13” needed to meet the requirement of R-38 for attics. This type of insulation is used in areas where there are large open spaces, such as cathedral ceilings. Fiberglass insulation is available that contains natural and recycled materials. CPS Energy offers rebates for fiberglass insulation if the specified requirements are met.


In Insulation Made from Recycled Materials—Fiberglass loose-fill insulation is made from glass, including 20-30% recycled glass, that has been spun into fibers. Cellulose loose-fill insulation is made from reprocessed newspapers that have been formed into a fibrous material. The insulation is blown into the area by machine and can conform to any space, making it ideal for locations that are hard to reach or irregularly shaped. Loose-fill insulation is used in enclosed existing walls, open new wall cavities and unfinished attic floors. Reduce your energy costs by up to 35% with loose fill insulation.
