roxul, eps, xps?
We are considering exterior insulation options and would appreciate any feedback from folks who have used or considered Roxul/Rockwool. I've spent a while looking at other sources and forum discussions which are fairly technical, but it appears that the main drawbacks to the product are cost and availability (or lack thereof)? Any insights would be appreciated! Architect and builder typically use XPS or EPS.
