Insulation information


Insulate Today, Save Energy and Money Tomorrow!

Today's homeowners are looking for ways to save - save on utility bills, save energy, save money. Research shows homes without the proper amount of insulation in an attic lose not only energy, but money as well. By adding the proper amount of attic insulation to their homes, homeowners could save as much as 20% on utility bills.

So How Much Insulation is in Your Attic?
According to the U.S. Department of Energy’s Insulation recommendation, homes in the Valley should have insulation with an R-value between R-30 and R-60 in their attic (see DOE Map). We recommend an R-Value of R-38 to R-49. R-Value is the thermal resistance to heat flow. The higher the R-value, the greater the insulating power.

How to Measure Attic Insulation?
Find an exposed area of insulation in your attic, or other location you would like to increase your insulation and measure the amount of existing insulation. Use the chart below to help determine your current R-value.

Economic Benefits of Insulation

  • Insulation reduces average home health and cooling / heating costs by around 20 percent.

  • Increasing the insulation in an under-insulated home results in a decrease in monthly utility bills.

  • One of the most cost-effective ways to make your home more comfortable year-round is to add insulation to your attic.

  • Insulation is an investment that lasts for many years and typically requires no further maintenance.

Other Insulation Facts:


Fiberglass insulation is made from mineral substances processed from molten state to an incombustible fibrous form.

Facings Facts

  • Standard facings will burn and should not be left exposed.

  • Residential facing should always be installed to the warm (heated) side of the dwelling for vapor barrier application.

  • Vapor barriers must have a rating of 1 perm or less.

Sound Facts

  • Fiberglass insulation increases the sound transmission class (STC) rating when properly installed in building assemblies. It has been determined that thickness has greater value in sound control than density.

R-Value

  • R-Value means resistance to heat flow. The higher the R-value the greater the insulating value.

Flame Spread, Combustion, and Federal Testing

  • Unfaced fiberglass blankets, unfaced metal building insulation, metal building insulation, FSK 25 and loose-fill insulation have a class "A" flame spread rating of 25 or less and smoke developed rating of 50 or less according to ASTM E84 test method.*

  • Unfaced fiberglass blankets, unfaced metal building insulation, and loose-fill insulation have been tested and passed the requirements of ASTM E136 combustion characteristics and are considered non-combustible by major building codes. All unfaced products meets Underwriters Laboratories fire design BZJZ and BKNV.

  • Metal building insulation has been tested and complies with ASTM C991.**

Recycled Glass Content

  • Guardian Fiberglass products contain 30% post consumer recycled glass and 5% post industrial recycled glass.
