CocoonŽ Insulation
R-Value High R-Value per Inch
Long-Term Thermal Performance
Cocoon outperforms other insulation materials in three important ways.
-
First, unlike fiberglass batts, Cocoon creates an uninterrupted blanket
wherever it is installed. Because it completely fills the areas where it is
installed, Cocoon's R-value is not reduced by gaps, voids or compression.
-
Second, tests show that Cocoon's high density allows it to retain its R-value
across a wide range of temperatures. These same tests show that the effective
R-value of fiberglass, in particular, can be reduced up to 50% as temperatures
approach 0° F.1
-
Third, thermal performance is more than just R-value. In many instances, the
R-values of some insulating products are less effective because their lower
densities allow air to flow through them. "The most common insulation,
Fiberglass, does not stop air leakage. In older homes, dirty fiberglass is a
telltale sign of air movement (it simply collects dirt like a filter)."2
Cocoon's high density greatly limits the amount of air that can pass through
it.

Fiberglass Data: For Fiberglass, the colder it gets, the less it works --- the
hotter it gets, the less it works. And it looses R - value as it shrinks from
the day of insulation.
