[Greenbuilding] Anybody used Retrofoam?

[Keith Winston]

Hmm... if you say "check out their web site", please provide a link. In 
this case, the spec sheet is the most substantive information I found on 
their site.

Anyway, I got misdirected, apparently, by the fact that their parent 
company is Polymaster, a big polyurethane foam company. Now I see what 
you mean, on the spec sheet there's much more specific information than 
I'd found (somehow I missed that the first quick pass through). This 
seems very interesting! It also seems very new, it's different (it would 
appear) than anything else out there, which means that all the 
weaknesses, problems, etc, have to be discovered. But on paper it really 
is quite interesting. Thanks for pointing it out! Here's the spec sheet 
link:

Warmly, Keith
