Alternate means to attach ceiling

[farok]

I'm trying to limit the amount of height I sacrifice when I install the ceiling, as I'm 6'1" and the ribs are 6'2" off my floor. With shoes if I stand upright, I'm brushing the roof ribs. I'd rather not attach the ceiling directly to the ribs (I'd need about twice the number of panels due to how I'd have to cut to fit), and that still wouldn't solve the issue of attaching one planned wall that will be about 10" from the closest rib.

My thought is to use 2x3s or 2x4s running perpendicular between the existing ribs as stringers, attached to the ribs with pocket screws so I don't end up any lower than the ribs. Can anyone think of a good reason why this would be a bad idea? This gets my ceiling as high as possible and allows me something to attach my walls and ceiling to, regardless of whether there is a rib where I need one or not.

I did my walls 1/2” sanded plywood with a 1-1/8” gap to allow air flow all the way around which also allows me to run wire cords plumbing pipes etc through the gap. I used toilet partition brackets

Looks good, and makes a lot of sense, especially for airflow!

However, I should have stated that I've already removed my metal ceiling panels to remove old insulation and install new, so I don't have the old metal ceiling to attach to, just the ribs.

I think it will work fine......same concept as attaching wood strips along the ribs, although not quite as strong.....but you're only supporting a ceiling.

Are you going to leave the ribs uncovered?

Thanks! I was thinking of putting thin foam between the ribs and ceiling - there will be maybe a 1/4" gap, if that. Something like this:

That product should produce a thermo break, but adds no insulation. It does state it is R-0 afterall.

Understood. I'm planning to put foam board in-between the ribs wherever I don't have stringers taking up the space. This is just a break.

Thanks all for the insights!
