Also, if you have to go with a standard foam insulation, there are 2 new
types of foam insulations that do not use CFCs or HCFCs:
1.	Icynene
a.	Icynene is a foaming agent that uses a mixture of carbon dioxide
<http://www.aerias.org/DesktopModules/ArticleDetail.aspx?articleId=138&s
paceid=2&subid=13>  and water. Though it does not have polyurethane's
HCFC-related environmental problems, it also has a lower insulation
rating (R-value). Like polyurethane, Icynene is foamed into wall
cavities, but the resultant open-cell foam is soft, not rigid. 
b.	http://www.icynene.com/
2.	Air Krete
a.	Air Krete(tm) is an inorganic foam produced from magnesium oxide
(derived from sea water). It is foamed under pressure with a microscopic
cell generator and compressed air; no CFCs or HCFCs are used. 
b.	http://www.airkrete.com/
