Drop ceiling options?

[absintheisfun]

40x60 metal building with spray foam insulation. I added r30 fiberglass insulation on the walls and finished it with mdf. I added a 24k minisplit that helps, but once the sun comes out, it loses the fight fast. The ceiling is spray foamed as well, but it's just not enough to fight the sun. I have been looking at options and would love to do a drop ceiling to reduce cooling space, and perhaps roll some additional insulation on top, but the cost is absurd.

I was thinking of getting the T-bars and grid and using iso foam as a ceiling panel, but even that is expensive. Anyone on here make anything that would lower the ceiling without being $5,000+? It's a 12 foot wall that goes to 16ft in the middle. I figure if I can get the height to 12ft throughout, it would reduce the cooling cubic feet dramatically.

Thanks for any help yall can give me.

Metal liner panel...aka thinner roofing metal with an indoor rated paint(cheaper) than the roof rated stuff

Easy to put up, no painting or finishing and can easily support insulation on top. Check the mfg instructions for what the span between rafters/trusses is

Bad side is it will make it a bit louder/more echo

You may also need to add additional cooling capacity - a 24k minisplit is pretty small for that size of a space.

When you say "metal building", are you referring to a red iron style or a carport style building? Is the roof structure rated to support the dead load of an insulated ceiling?

Liner panel certainly works (it's what I use), but will require some framing. I expect you'll end up under, but nearing, that $5k price point with framing, liner panel, screws, trim, and insulation all included at today's prices. That said, location definitely matters here, and we have no idea where you're at.
