Hvac Ductboard on walls?

[InbredEd]

Can i cover my walls with sheets of ductboard? its the fiberglass board with a foil backing that's reinforced with nylon string that HVAC duct work is sometimes constructed of. my concern is the reflectivness. i cant find any word on anyone using it. i have a source for it in three different thicknesses.

I would think it would work great. It is pretty much the same as inside of a tent. I would use it. It would be safer then using foil covered wall foam. Fire can be a issue with that. But I did use some before I got my tent and it worked fine.
