KR> experimenter Polyisocyanurate Foam
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.

-- Thanks Dave, I compared properties of the two and found : Both are made by "Dow" and are suppose to be unaffected by ethanol laden fuels. "Tuff-R" has a much higher flexural strength & will absorb much less moisture. There's a locale supplier that carries up to 2" thickness and the price is right! The possible draw back for Tuff-R": an operation temperature range of -50 to +190 F. and having to remove facing materials from each sheet. The plus for "Trymer 2000" is it's operation temperature range of -297 to +300 F, but I don't remember seeing that product name in my travels so far. It seems Urethane Foam has an operation temperature range of 65 to +200 F. I guess my next question is, "What do the high priced urethane foams have that 'Tuff-R' doesn't ? " ----------- Subject: Re: KR> experimenter Polyisocyanurate Foam You should also look for Trymer 2000. I found a supplier nearby a few years back, but they don't carry it anymore.

Is anyone using Polyisocyanurate Foam, (e.g. Tuff-R) in their construction? The last mention of it on the search engine was by Dean Cooper, Sept 2004 Ron Haskell, Barrington, NH rehask...@metrocast.net
