Couple questions: 1. Please remind me of why (other than environmental toxicity and flammability) early on you rejected using the 2" thick white (EPS) polystyrene foam boards in favor of the polyiso foamboards?
2. If your only choices -- as are mine locally -- are between EPS and XPS, which would you choose and why? (As in http://www.homedepot.com/h_d1/N-5yc1v/R-202090328/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053 vs. http://www.homedepot.com/h_d1/N-5yc1v/R-100320352/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053, for instance. 3. Was an argument against EPS its lack of rigidity? 3. Was it water permeability? I understand that the EPS styro sops it up (and loses insulating ability in the process) and that XPS doesn't. 4. If you were going to throw up a quickie small building and would be encasing the foam boards in fidobe papercrete and a fibrous-cement-like shell in and out, would you still rule out the less expensive white styro boards for the initial building? Or would you forgo foam altogether? Thanks, ken winston caine -- You received this message because you are subscribed to the Google Groups "hexayurt" group.
