Thick Walls

The walls in part of my basement (All above ground level) are framed 15'' deep, do I need to build up to that thickness with fiberglass insulation or is it OK to leave air gaps in the wall?
Thank you,
Anthony

Can you provide some pictures? I can't figure out why they'd be framed like that in the first place.

Hope this helps... Only the upper section will be getting fiberglass batt, the concrete is getting spray foam, would like to have spray foamed all of it but the cost made it impossible.

its ok to leave air gaps behind the fiberglass. i would say go with like a R-19 or R-30 in the wall though. The important part is where the foam stops and the fiberglass begins, that they both butt up and seal together with no voids
