no basement insulation an option?
Our Township Code Official here in NJ has said that if we put XPS on the walls, we'd have to use furring strips b/c there can be no space between the XPS and the drywall for fire safety (Doesn't furring strips provide a space though?)
I don't want to use furring strips b/c of the easier install of electrical wiring.
The Township won't accept XPS within the frame.
If I build a standard 2x4 frame, he said I would have to use kraft-faced insulation in order to have a vapor barrier (I can't use the XPS in this situation)
I have an interior perimeter drain system with 2 sump pumps and back-up. We're planning to put in a subfloor of XPS and OSB (Barricade) and then carpet over this. We've relandscaped and all gutter spout have been extended away from house. There has been no smells in our basement and no mold problems. We have humidifiers running down there that hose right into the sump pumps.
I'm not required to have insulation b/c I have a gas furnace that is >90% efficiency. Since insulation absorbs so much moisture, I'm contemplating not putting in any insulation in the walls at all and talk to my HVAC guy about the appropriate ventilation requirements.
Any advice on this proposed plan? Anything I'm missing? Will we be paying a fortune in heating bills?
