A typo here, it should be EIFS, not EFIS. (Exterior Insulation Finish Systems). Now there is a HOW TO EIFS detail document put out by a legitimate authority EIFS Council of Canada. Be warned, you still need to design it to shed water, but the Ontario Building Code regulates it now.
No longer uninsurable. I checked with ProDemnity, our insurer. http://eifscouncil.org/
