We're finishing a kitchen remodel and considering using cedar slats
for our ceiling. I'm curious, does anyone know if most building codes
require the ceiling to be non-flammable, or at least have a layer of
I noticed on most paneling, it says you shouldn't fasten directly to
studs, that you need a layer of non-cumbustible materials (ie,
drywall) behind it. Does that apply for ceilings?
Right now , it's just exposed 2 x 8 s and the second floor subfloor.
Was going to attach the slats directly to the 2 X;s.
Thanks for any info.
It's definately required that you have a fire-rated barrier between
floors if it's multi-family, but I'm not sure about single family
It's a good idea to put sheetrock under (over?) the slats anyway,
both for safety, and because this will reduce noise and dust transmission
through the slats.
We used 1x6 T&G cedar boards on the ceilings throughout our house. I
specifically asked the inspector if we needed to install drywall before
installing the cedar. He said the drywall is for fire protection and since
our home is single story, there is nothing above to protect. So, we were
able to nail the boards directly to the ceiling joists.
However, if there were a room above, we would have needed the drywall
behind the cedar.
As in most (?all?) code questions ask your local inspector. Codes
vary from one place to another. Don't rely on a code answer you get
from the internet. As someone else mentioned put on sheetrock first
if for nothing else than dust protection.
Once code req. are met keep in mind the boards will shrink, and you will
have lots of drafts, dust as was mentioned, no way to fix after the
finish is on. Do yourself a favor and put up sheet rock first, even if
you only put sealing tape over the joints. House will also be quieter!
