Hi, I have a cathedral ceiling with 2X12 joists. We will be putting R30 insulation in it however In numerous places the electrician ran wireing up 4 to 6" from the bottom across the bays. We need to have a couple inches of air space above the insulation for air circulation but with the wireing running so high across many of the bays this will be difficult. Any ideas?
Thanks, Ed

I would suggest you install stryofoam baffles or vents continuosly in each run to the underside of the roof area.
This will allow air flow to be maintained.

When installing the insulation batts, where you come to a wire just seperate the batt in the cent and run over and under the wire so as not to compress the batt. compressed fiberglass batts loose there effectiveness rapidly.

Also If you are putting recessed lights in the ceiling area,
realise that a huge amount of warm or cold air will enter through those openings. Usually they take up to much space to allow for insulation of any value to be installed.

Good Luck
