Are You Getting What You Pay For?

The choices you make about insulating your home deserve some careful attention. After all, you’ll be living with this decision for as long as you own your home!

What do I really need to know about insulating my home?

Aren’t all insulations the same?

No. Absolutely not. The R-value listed on insulation products is a standard that comes from laboratory testing. Real world tests demonstrate just how vastly superior Applegate Cellulose Insulation® is in comparison to conventional fiberglass.

Applegate Insulation® has an R-value of 3.8 per inch, nearly twice as much as typical blown fiberglass!

For example, Researchers at Oak Ridge Laboratory found that, “R-19 (glass fiber) batts have an R-value of 13.7 when installed as commonly found in actual walls.”1 And other tests determined that on the hottest and coldest days, fiberglass’ efffectiveness decreases while Applegate Cellulose Insulation® maintains its full insulation value.2

How is that possible?

Insulated pipesThe walls, ceilings, and floors are full of odd shaped cavities and obstacles like plumbing, air ducts, and wiring. According to Guardian Fiberglass, “About half of all wall cavities in residential construction are nonstandard in width and height, or obstructed with wiring pipes and other things. Any void area in conventional batt insulation can reduce the R-value significantly.”

For insulation to work effectively it must completely fill around these obstructions without voids or gaps.


The Applegate® Difference

Blowing in cellulose insulationApplegate Cellulose Insulation® is sprayed or blown into walls, conforming to your home and surrounding you and your family with a tight thermal barrier.

Fiberglass batts, on the other hand, are cut and pieced together, leaving voids that reduce it’s ability to insulate. So even though it may be less expensive to install initially, fiberglass batts do not deliver the same effective insulation properties as Applegate®.

Sealing the building envelope with a seamless blanket of natural fibers, Applegate® can also be installed in attics and cathedral ceilings. Applegate Stabilized Cellulose® Insulation locks in place and virtually eliminates dust and settling.

“Utility bills were 32% lower in the cellulose insulated

-Leominster Housing Authority

Another study compared fiberglass and cellulose insulation in attics.3 Both started at R-19, but fiberglass started to lose its effective R-value as temperatures dropped to just 32º! It went on to lose up to 50% of its effective R-value as temperatures continued to drop.

Applegate Cellulose Insulation®, however, not only maintained its R-value; its insulation effectiveness actually increased to more than an R-20 as temperatures were lowered below -18º F! When you choose Applegate Cellulose Insulation®, you will receive what you paid for!


Reduce your heating and cooling bills
up to 32%!

If your new home was insulated with fiberglass, adding a layer of Applegate Insulation® to your attic boosts r-value and cuts utility costs.

Older homes usually have very little insulation in the side walls and attics. Adding Applegate Insulation® will help lower your heating and cooling bills.

What can I do for my existing home?

Whether your home was built a century ago or completed yesterday, it’s not too late for you and your family to enjoy the benefits of Applegate Insulation®. Your attic and walls may be insulated with fiberglass that is doing a poor job. Covering the loose-fill fiberglass in your attic with more of the same stuff “fails to restore the lost R-value”4 that naturally occurs with fiberglass. But


researchers at Oak Ridge found that when you “cap” your loose-fill fiberglass with cellulose, it not only adds R-value, it actually restores the effective R-value that fiberglass loses during cold weather.5

Many older homes were built with little or no insulation in the sidewalls. Your local trained Applegate professional can add Applegate Insulation® to your homes’ sidewalls, making your home more energy efficient—saving you money!
