Cathedral Ceiling Insulation Advice?

Looked at dense packed cellulose for the unvented application?

A few years back I almost bought a camp with a uninsulated cathedral ceiling and it was like 110 in there in August. After all my research I kept coming back to right packed cellulose.

Just renovated our house this year, including a cathedral ceiling, and never heard of putting the Kraft paper to the outside. My understanding is that kraft paper is flammable and needs to be placed against gypsum board.

Re: baffles, if you have a vented cathedral ceiling (which, from your mention of an airspace you do), you have to maintain that airspace from soffit to ridge. That typically requires a baffle at the soffit.

We used a foil radiant barrier from soffit/top plate to ridge, with spacers to maintain the airgap required for ventilation. Followed by r38 cathedral batts in our 2x12 rafters.

I'll look into dense packed cellulose. So far I've been leaning towards vented, though.

My bedroom ceiling was originally 24' cathedral we lowered to 18', so there is a 6' gap in attic, but we did spray in walls and cellulose in ceiling in that room. I've never heard of facing paper the opposite way.

I will say my bedroom is the coldest room in our house during the summer, we have 10' everywhere else down except living room is 11'.

I have seen this done so many ways and I really dont know what’s “the right way”. I would not use paper. Look into roxul. You’ll get a better product.

Is your soffit vented? I think I would want to eliminate any moisture being introduced to that space. I would not put baffles and if your soffit is vented I would seal it.

What is going to be your finished ceiling?

Have you looked into using baffles and doing a dense packed blown insulation instead of batts? You'll get much better results with blown.

I recently installed vented soffits. The people that I bought the house from had painted over the soffits and sealed almost all the holes in the soffit. They also had gone into the attic and stuffed fiberglass insulation into the areas where the cathedral ceiling is supposed to vent into the Attic. I've been having a mood issue plus that room is always super hot. Since I removed the insulation blocking the flow from the ceiling into the attic and put in the soffit vents I no longer have the mold issue. When I cut out a section of sheetrock that had water damage I could see that the insulation is very old dirty flattened fiberglass insulation so I want to remove all the sheetrock from the ceiling, change out all of the insulation, and then put up new sheetrock.

I have not yet looked into dense packed blown insulation so I'll read up on it.
