I want to Insulate this barn, it already has drywall and pink insulation around the walls, but nothing on the roof. The roof also doesn't have a ceiling. What is the best route to go for the cold winter coming up?

I was thinking Radiant Barrier, would that work? Or should I just stick to Drywall and Standard Insulation?

Not knowing all of the particulars of the roof, I'd suggest one of 2 options:

Frame in a flat ceiling 2-? ft below the roof line, then blow insulation on it.

Frame in a vaulted ceiling and install batting.

I would not suggest insulating between the rafters as they are now.

good luck
