Insulation between cinderblocks and drywall


I am removing old drywall from an exterior wall.
There is no insulation between the cinder block and drywall.

Should i install insulation? It seems like the right thing to do.
What is recommended?
The house is located in Illinois.

thanks allot

Are you sure that's right? An exterier wall with drywall on it?
Did you mean it's on interier wall you removed it from that is an outside wall?
Spray foam or at least blue foam with low expanding spray foam to seal any gaps.

Yes, it should have insulation.

There are a myriad of thread on here and building science.com that detail different basement wall insulation strategies.

Insulation between cinderblocks and drywall


wheres the best place to insulate a cinderblock and brick wall above grade? Is it between the cinderblock and brick?
Should that have a "vapor barrier" whatever that really means.
Vapor barrier = water impenetrable membrane?
If you have a vapor barrier one side will be wetter and the other dryer?

Should there be insulation between the cinder block and drywall or should that be allowed to breath.

insulation and vapor barrier are not the same thing.
True or false.
Sometimes you want insulation w/o a vapor barrier. Yes or no.

thx for input.
