OK, I know I have read here that you can use plywood for the underside of a wide soffit, then drywall.


Here's what I'm facing. I made a measurement error when constructing the vertical "ladder" of the soffit. It does not allow engouh clearance for a stud going across to the other vetical portion. It would allow for the plywood to go across without touching the ducts.


If allowed, what size plywood to use? The span is a few inches over 4 feet.


Thanks,

ok, after thinking about it, maybe I'm just being silly, and I can just run some 2x4's across the bottom? I am using steel studs, but can easily attach the wood. Are 2x4's necessary, or can I use 2x3's?


Thanks,

Steve

OK, another question (for those in the viewing audience. How far can I span the metal track for the underside of the soffit?

Steve, in one section of my basement, I am planning exactly that because of the height issue. That means only drywall is attached from bottom of one vertical ladder to the bottom of the other vertical ladder. But the span is not as wide as yours.

I am using 2x2s for the soffit in my HT.

so you are using plywood or osb? What thickness?

I plan to use 1/2" mdf for my ht soffit, no drywall. The other section with the height issue is not a part of HT I plan to use 1/2" drywall only.
