Inquiry (采购产品): Garage Roofs I am a general contractor in Breckenridge, CO. I would like to install SIPs on a 45'x 22' flat roof garage with existing 4x12 ceiling joists at 4'o.c. We don't need a lot of R-value because the garages are not heated. What would you need from me in order to get me some ballpark pricing for my clients?
