Cavity Fill
Insulation:
Alternatives
by Alex Wilson
Concern about ozone depletion is
proving to be a boon for
manufacturers of cavity-fill foam
insulation products that do not use
CFC as the foaming agent.
Tripolymer Foam, Icynene, and Air-
Krete are three such products, and
while very different, they all produce
a rigid or semi-rigid cavity-fill
insulation and offer an alternative to
spray urethane, cellulose, and
fiberglass.
Tripolymer Foam, Icynene,
and Air-Krete do not use
CFC as the foaming
agent...a plus with all the
concern about ozone
depletion.
Tripolymer Foam
Tripolymer foam, manufactured by
the C.P. Chemical Company in
White Plains, N.Y. is a phenolicbased
foam, chemically similar to
Koppers' phenolic foam. The primary
difference is that air rather than CFC
is used as the foaming agent. There is
no harm
