hi guys, quick insulation question. I have a 30x40 pole barn that has foam board insulation in the walls and a thin layer on the ceiling....I have 16 ft sidewalls so losing some heat up top...wood stove does well, but want more constant heat so thinking about a large propane heater, but don't want to do this until my ceiling insulation is better. can I use fiberglass insulation and leave it uncovered for a while? as I don't want to spend a ton of money right away, or will I run into issues with leaving it uncovered? I attached a picture to give a more visual idea of look. thanks

"...more constant heat"
More wood to the stove! More insulation doesn't necessarily equal more heat.
But, if you want more heat at the floor instead of at the ceiling- Big *** Fan! Circulate that heat...

sry, I guess I should a worded it better...the stove heats it fine but I'm wanting to keep it around 40 in there at all times with a heater and thermostat and don't want to waste this heat with an uninsulated ceiling....I have a couple of big fans hanging I use as well.
How thin is that foam? I bet if you climb a ladder you will find its alot warmer up high. On the cheap you could use a fan to circulate some of that heat back down. If you dont need that full height like for a lift or something, you could add a lower ceiling. If heat is escaping I think spending more on heat would be a waste. Fiberglass can be exposed but if you put it over too thin foam without an air gap could cause moisture issues.

Let's start with your location, there's a place for it at the left under your name. It helps everybody give good responses. Many people on forums won't even reply if there is no location listed. I'm worried about adding much weight, do you get snow? It appears the purlins are 2x4 and the trusses 9ft apart. Is this correct?

People keep saying "ceiling", but what I see is a hot roof. Much better off with a ceiling and an insulated attic.

I don't think adding insulation to the bottom of the roof is going to give you the results you are looking for. Heat is still going to rise, and insulating the roof more will just mean it will stay warmer up at roof height. As others have stated, your best bet is to decrease the total volume of airspace you are trying to keep warm. If it were me, I would put some light weight ceiling on the bottom of those trusses. My first though is a commercial drop ceiling, which Is light, and could probably be hung off those trusses without adding any more wood up there.
