If you build a home using 6 1/2" SIP's for walls and ceiling then using the roof as a "shade" for the box (house w/o roof). What would be the optimal set up for the metal roof to try to keep the attic space cool? ex: deck/insulation/etc. The ceiling SIP would allow about an R 26 value, so the attic ventilation could be very aggressive in moving air through the attic space. Any thoughts would be appreciated. Thanks.		Guest User 11/13/2005	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/7065/find/
Balanced air flow just like the building code calls for, 50% at the eave and 50% at the ridge. Supply minimum one sf of free air for every 150sf of ceiling area.		Allan Reid Dura-Loc Roofing Systems, Inc. 11/14/2005	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/7066/find/
