Choosing an insulation product for your home is something you'll literally have to live with for a long time. But when you compare Cel-Pak to the alternatives, it's an easy choice.
"Money's no object." Have you ever used that phrase when you were building a new home or renovating your current home? We didn't think so, and neither do most people, so let's get something out of the way up front:
Cellulose insulation isn't the least expensive insulation you can buy.
But here's what you really need to know. Cellulose insulation, while it costs a bit more when you install it, is going to save you more money every year on energy costs. But don't take our word for it.
The University of Colorado School of Architecture and Planning1 built two identical buildings to compare fiber glass insulation with cellulose insulation. They concluded, "The cellulose insulation alone tightened Building A approximately 38% more than fiber glass tightened Building B."
A tight building means less air infiltration or leakage. What did that mean in terms of energy savings? "The cellulose building used a total of 315.75 Kwh…This represents more than a 22% difference in energy usage." Due to other factors in the study, they also said, "…these relative percentages of heat loss when cellulose is used compared to the use of fiber glass may be on the low side."2 Which means the energy savings from the cellulose insulation may well have been even better than they measured.
As you'll see in our FTC required footnote, savings vary. And while higher R-values do, indeed, mean higher insulating values, R-Value doesn't measure the effects of air infiltration on insulation performance. So shouldn't you choose the insulation that does a better job of preventing air infiltration?
