You need to look at the venting, the soffet and high vents are really important.I am new to this community so, Hi to all. I am trying to finish an attic with cathedral roof from an 1890 house that has no soffit or top vents. The ceiling will be where the collar ties are (a little less than 8 feet tall) so there will be a kind of crawl space still left at the top. I did knee walls but I am planning on running insulation on the wall as far down as I can so I can insulate the empty space behind the knee walls (using for storage and A/C duct)
My question is, do I need to use baffles behind the insulation? Is there any scenario where I don't need to use baffles?
The ridge vent is not much a problem, what are you looking at for soffet vents
Did you build the nee walls out of 2x6 for good depth of insulation.
The sloped part of the ceiling will likely need more room for baffles and enough insulation.
did you solid block between the joists below the nee walls?
