I have access to some inexpensive double-bubble foil insulation
I'm building a home with cathedral ceilings 8/12 pitch exterior, 6/12 pitch interior. Thinking of using the foil as a radiant barrier at the bottom of the top cord of the truss. This will create a baffle to vent roof . Then using the foil bubble wrap in the interior of the bottom cord of truss then use furring strips to create an air space then drywall. Then fill void in truss webbing with blown cellulose.
Will using vapor barriers in this configuration cause any problems? House to be build in zone 4 Tennessee.
