KR> experimenter Polyisocyanurate Foam

[mbz...@comcast.net]

You might want to double check the Tuff-R 



I think it has an aluminum laminate on both sides 



I'm not sure, but if thats true, the laminate IMHO makes the foam useless 



for construction. Also I'm not sure if the properties of the foam are with or 
with out 



the aluminum laminate. So if you peel the laminate away, the properties 



might go down the hill.

Hi Netters, Let us remember that some foams give off a very toxic gas when cut 
with the hot wire method.
