I'm currently struggling to explain why I want SIPs for my roof instead of trusses
My designer and I are designing a house as close to passivhaus standards as we can get. We have agreed to design it with SIPs but he thinks a truss roof with spray insulation would work just as well. I'm thinking a SIP roof eliminates potential for thermal bridging and is less costly to install versus the truss roof.

Is it advisable to use nail base insulation panels over a roof insulated with closed cell spray foam?
