Sauna Roof and Wall Assemblies #green

I am planning to build a small sauna structure in Ontario with a zero overhang unvented roof, open-joint cladding with rain screen, Delta Fassade S membrane or similar on the walls (and possibly roof), DensGlass sheathing, rock wool insulation (R14), and a foil vapour barrier on the inside with taped seams. The reason I want to use the foil VB on the inside is because people will be throwing lots of steam as well as washing up inside the sauna. So, will this system work? Or should I opt to use airtight DensGlass on the inside with a flash coat of spray foam under the roof sheathing as well as rock wool? I have been having a hard time coming up with a solution because there is not much documentation of these types of assemblies being used on a sauna. Also, is there anything else inherently wrong with this assembly?
