I'd like to know what I can use as an ignition barrier to cover spray foam insulation, or foamboard insulation such as Rmax, besides sheetrock. This would be for side attic applications, or basement rim joist applications where we need to cover the foam insulation with an ignition barrier but I want something easier and cheaper to install than sheetrock.

Sheetrock is only about $8-10 a sheet. That is pretty cheap unless you need 5/8 fire rated rock. That is more expensive but this is not an area to cut corners. I have been through a house fire. You could have serious regrets if you shortcut and lord forbid you have a disaster.
Fires can happen to anybody without warning. It is not worth cheaping out to save a couple bucks.

Sheetrock might be the cheapest option but I would look into the building codes in your area as some only allow for the use concrete and masonry.
are you wanting to create a electronic barrier? or insulate,?
or stop the foam from catching on fire ?
spray foam wont support a fire when cured, it will smolder,
dry wall will do the same, just cover it with sheet plastic,
