Hello,
I was talking to a house building consultant and he was recommending SIP’s for the roof. Is this a good alternative to persue?
I was planning on doing conventional stick framing, sheathing with 5/8″ plywood, then insulating the attic floor and areas where the roof slope forms part of the ceiling of the room with either spray-foam or conventional fiberglass (or combo of the two). [I’ve also considered spray-foam on the roof and unvented roof]. House is in central North Carolina.
What would you recommend?
Thanks,
Roger <><

Do you own a crane?
SIP's have a big advantage in cathedral ceilings. In an attic situation I would not use them if I was building the house by myself.
you can also apply SIPS to the inside of the attic trusses if you want to go with an un insulated attic space - this is much easier and doesn't require a crane. However I'm not sure how much it will buy you in your area? NC doesn't need the super insulated roofs that we do up north. and it is more expensive than regular insulation. But it is nice for exposed truss or rafter cathedral ceilings.
I have them, I love them! The benefits are really worth while! would you like to know the real differances I experianced with mine?
If the attic is going to be livable space I'd think the SIPs would be a great idea. I watched my neighbor build a new garage this last year with SIPs. The structure has a second floor for his wife's studio space, and it's very nice. Great insulating qualities, lots of wide open space, and the SIPs make it nice and quiet up there too. Construction went very quickly with a crane, the basic structure took them less than two days to assemble.
