Laying batt FG insulation over attic floor


Small (900sf) house in Tennessee has no insulation under plywood flooring over joists. Started laying batt FB (w/ vapor barrier) insulation between joists behind knee walls. Don't want to pull up plywood flooring.

Thinking of just laying batt FB insulation directly over plywood flooring.

Question: Should I use a vapor barrier directly over plywood floor or just use insulation w/o vapor barrier?

Is the floor you are describing over a crawlspace? I think you have some of your terminology mixed up.

Can you post up a picture?

Joist are under the house and rafters are what holds up the ceiling, is that what you ment to say?

Laying batt FG insulation over attic floor


Sorry for sloppy terminology. I'm inquiring about an attic space. House is wood frame with gable roof. Wood rafters over attic. Plywood flooring in attic over 2x6 wood ceiling joists.

Attic is not being used for storage, so covering floor with batt or loose insulation is an option we're looking at.

Question is if we should lay down a vapor barrier over existing plywood flooring if no insulation/vapor barrier is between ceiling joists.
