Cathedral Ceiling

Posted by John Reichert on December 7, 2008, 6:21 am

The kitchen of my house has a cathedral ceiling. The room is cold in the
winter and hot in the summer. The house was built in the late 70s and I'm
reasonably certain, there is little if any insulation between the ceiling
sheet rock and the roof. I can't get into the area between the ceiling and
roof to inspect. Any frost or light snow on the kitchen roof melts quickly
whereas all the other areas of the house with a flat ceiling and 13 inches
of cellulose above, do not. I would like to insulate the ceiling from the
inside and then install either a suspended ceiling about 8 foot from the
floor. I'm looking for suggestions.

Thanks John

John, a flat ceiling is fine. You can install a drywall suspended
grid, this is the same type system as a commercial drop ceiling
with slightly wider faces made to screw drywall to. You would
need to do the insulating before installing the gyp. You might
want to consider a more decorative approach as long as you have
the cathedral height. Look through this Trim Tex site for some
ideas:

especially the drywall art section:
look for the gallery section and the videos

You can insulate the ceiling and then any which way "drop" a ceiling.
One of the important factors in this consideration would be to provide
adequate ventitlation between the roof deck and insulation as to allow moist
air out. This would include any of these: metal roof vent, "cora ridge"
vent, gable end vent, and also some "bird hole vents" and or strip venting
to provide a flow in at the lower rake of the roof. Descriptions of these
are readily available by searching roof ventilation.

Personally, I'd suggest installing your new dropped ceiling with
insulation on it, and not 'messing' with the cathedral ceiling at all.

I think a cathedral ceiling is a nice feature and I would hate to give that
up. I would explore other possibilities such as removing the existing
drywall to install better insulation and maintain air flow or at the very
least look into blown-in insulation. After that I would install an
additional layer of drywall with a radiant foil in between drywall layers.
I would also install a suspended paddle fan to keep heat from accumulating
up there. Perhaps for the summer a small exhaust fan at the peak would help
with the heat load or locate an A/C return vent up high.
