So far I've read that ducting channels can be made from drywall only. I'm
not interested in enclosing the ducting all the way, it isn't necessary for
where I'm working, so my question is when I install the drywall, is it okay
to butt the drywall up against the ducting or should I leave a gap? I'm
wondering if thermal expansion of the ducting makes it necessary to leave
space or if there are other considerations that make leaving space
necessary.



If you leave space, you have created at no extra effort a conduit or
chase for tv cable
( quad shield RG6 co-ax, etc); network cable (CAT 5 / CAT 6);phone
(POTS) cable,
fibre optic cable, etc.

Put in 4 or 6 pll strings the lengtof the outside of the ducting but
inside the drywall enclosure.c

IMHO you can't have too many conduits or chases that you can use without
lotsof wa;ll board cutting. You never know what the future will bring.

I've re cabled (or just plain cabled) two older houses. Clear runs
without a lot of wallboard
cutting or stud drilling are your friends.
