Need help with my SIP roof assembly
We are planning to use SIP’s for our roof. Right now we have specified the following assembly (inside to outside):
-8″ polyurethane SIP
-1″ XPS foam insulation
-1/2″ plywood sheathing
-standing seam steel panels
We are in Omaha, NE (climate zone 5). Some of this is based on Martin’s advice from another question on this site (https://www.greenbuildingadvisor.com/community/forum/energy-efficiency-and-durability/18127/most-cost-effective-system-energy-efficient-h).
Any thoughts on this assembly?
