[GBlist] re: SIP roofs rot in wet climates

[Chris Koehn <chris@koehn.com>]

Scott-

I don't think the article really said that SIP roofs are generally a bad
idea in wet climates. I've read the SIPA (structural insulated panel assoc.)
report, and while I think there's still a fair amount not known, it seems
that poor installation, poor treatment of penetrations, poor- or
non-existent- sealing at the panel joints, poor vapor barrier treatments,
and (probably most importantly) poor ventilation/dehumidification detailing
significantly contributed to the problems.

I think that SIPs may be particularly sensitive to proper installation and
ventilation in extreme conditions, but to say that SIPs don't work in damp
climates as- as of yet- not accurate.
