hi... I have a outside room additiom 12x12 insulated walls and ceiling... 2x8 floor jouises no walls around the bottom... its like built on just the corners... so under the floor is all open to the air... if I insulate with 8 inches of fiberglass...
what should the under side of the floor be coverd with... I m guessing plywood to keep out the varnets... ect... plastic... then plywood or just the plywood or what? I live in md... so mainly I'm just trying to keep out the cold air from under the floor... from the winters...
thank you for your time and help... richard
