By no means am I saying you are incorrect in filling those areas but I also saw another method of allowing this air gap so it could be conditioned, now this of course means you would need to have the ducting to do that of course which I know is not common at all.
I just saw this. Thanks for your comment. Not sure I follow it - I do know that in my market (ATL) this technique I am describing works very well for our clients. Thanks for watching!
this is exactly my house and the many problems im facing, how or sort-of the best way to fix this? im about to blow in 18" of insulation to see if that helps
Sure. Thanks for your question! We drill holes in the garage ceiling and pump insulation into the voids of the floor system. When finished, we plug the holes. Check it out on my website, and my facebook page too. Lots of info and pix and vids. www.Birdinsulation.com
@@birdfamilyinsulation5411 - thanks! If the bonus room was above living space (and the bonus room subfloor was uninsulated), is the only option to go up through the ceiling of the living space?
@@LesterHightower If the room is positioned above conditioned space, then the floor system is typically left un-insulated. If this troublesome room has an attic, consider adding more airflow to that room by replacing the current supply-air duct with a larger diameter duct, or converting the existing supply-air duct into a dedicated duct (if it's a branch duct currently). Also, be sure that this room has a return-air vent.
