I've done some research into SIP (Structural Insulated Panel) for house construction. Very nice idea, high R-value for minimal extra costs.
The big problem I couldn't get comfortable with is the lack of repair-ability.
The inner surface and outer surface is glued together to form the structural wall.
What happens in 20 years when you (or the new owner) finds the SIP roof panel rotten? (roofs leak destroys the outer layer, and maybe the wall too).
There isn't much repair options. ....at least from what I could find.
