Cellulose insulation and the process of weatherizing and insulating a building involves a number of technical terms and concepts. We've compiled this glossary to help you decipher them.

Damp sprayed cellulose
Damp sprayed cellulose refers to cellulose insulation to which a small amount of moisture is added during application. It is most often applied in new construction where cavities are open, just before the application of interior coverings such as wallboard, drywall or paneling. The moisture serves to activate starches in the cellulose, allowing it to adhere both to itself and to the surfaces of the cavity
'Dense packed' refers to cellulose insulation installed in a cavity
, either dry-blown or damp-sprayed, to a density of 3.2-3.5 lbs. of material per cubic foot of space, or approximately twice the settled density
of the material. The process by which a space is dense packed is referred to as "dense packing".
An acronym for 'Do-It-Yourself'.
Embodied energy is a measurement of the energy that it takes to manufacture something, and one way to quantify a product's environmental impact. Simply put, if it takes less energy to manufacture one product versus another, it means that product has less negative impact on the environment - sometimes a lot less - and that's good for everyone. Cel-Pak is especially stingy in this regard, when compared to the alternatives. Relative to cellulose insulation, fiberglass and foam insulations take much more energy to produce.1
A more comprehensive approach to embodied energy is to look at the Global Warming Potential and Life Cycle Analysis measurements relative to energy usage. According to the University of Minnesota's 'Minnesota Sustainable Housing Initiative' research2, by these measures, when compared to cellulose insulation, the life cycle of fiberglass batts feature:
- 683% greater energy consumption
- 728% greater global warming potential (in lbs. of CO2)
- 1,850% higher air pollution index
That's not good. Sprayed foams? They take far more energy to produce than fiberglass, which means they have far worse environmental effects.
If you want to save money on energy and take it easier on the environment over time, Cel-Pak cellulose is a great choice! Insulating your home or business with our cellulose insulation products is an opportunity to do well (save money) by doing good (lessening your environmental impact)!

An Energy Audit is a comprehensive evaluation of a structure to determine its relative efficiency, the efficiency of its systems and the need for air sealing. It typically is performed by a trained professional, who prepares a list of recommendations or upgrades to be considered in lowering a structures total energy usage.
