Bonus room floor insulation
New construction, zone 4 on the line of zone 5 (47460).
Bonus room over garage with radiant floor heat in concrete floor.
My floor system has some areas that are blocked off with framing to add support to the ends of the floor in the bonus room. What can I do to insulate those blocked off areas before the ceiling goes in? Would 3.5" of open-cell be enough tot help with keeping the bonus room warm or would it completely block any benefit of migrating warm air from the below garage floor?
I plan to blow in cellulose once the ceiling is installed in the areas I can get to, then I will block off the ends with rigid foam and picture frame those with spray foam for an air tight envelope. Just don't want to do the wrong thing before the ceiling drywall goes up.
Would a batt in this area do the trick? it's a 2x12 bottom cord on the trusses.
