The truth is…not all insulations effectively combat all three kinds of heat transfer.
Unlike other insulations, Applegate Insulation effectively combats all three kinds of heat transfer. Applegate Insulation with an R-Value of up to 3.8 per inch, can be installed as a dense monolithic block in walls and as a blanket in the attic which significantly reduces air infiltration and acts as an effective barrier to heat transfer.
Whether your home was built a century ago or completed yesterday, it’s not too late for you to enjoy the benefits of Applegate Insulation.
Covering old low-density loose-fill fiberglass in an attic with more of the same stuff “fails to restore the lost R-Value” that naturally occurs with fiberglass. But researchers at Oak Ridge found that when one “cap” loose-fill fiberglass with cellulose, it not only adds R-Value, it actually restores the effective R-Value that fiberglass loses during cold weather.
A study "Testing And Analysis Of The Comparative Performance of Cellulose Vs. Fiberglass Insulation" conducted by, "The state of Colorado Technical Energy Consultants for Homebuilders" reports; "...by conducting a controlled side-by-side test of fiberglass and cellulose insulation systems, this study indicates that the use of a properly installed cellulose Insulation system can significantly contribute to the reduction of air leakage in wall cavities and attics, thereby reducing the building heat loss and utility bills. It appears that the short fibers of the cellulose material, and the blown-in application, allow it to fill voids more effectively, while the higher density minimizes air movement. the average performance of all homes tested showed cellulose with a 25% to 35% reduction in infiltration when compared to fiberglass. The average impact to utility bills was a projected 12% to 14% reduction in space heating costs."
Many older homes were built with little or no insulation in the sidewalls. Your local Applegate installer can add Applegate Insulation to your existing home’s sidewalls, making your home more energy efficient — saving you money!
What R-Value should I have in my house?
How much Applegate Insulation you should have in your home will vary based on what type of climate you live in, the construction of your home, what heating equipment you are using and what type of fuel your heating system uses. The U.S. Department of Energy has put together some recommendations for minimum R-Values based on where you live in the United States.
