[Greenbuilding] SIPs vs. fix/improve the roof/ceiling

[Keith Winston]

I'm not sure this product would be of any use in standard mid-atlantic 
residential wood-frame roofs with composite shingles, but it certainly 
could be useful for some commercial reroofing applications. I'm not sure 
it would be the greenest choice there, though with an added radiant 
barrier it could really reduce heat gain, I imagine.
