(Good sound insulation, doesn't get eaten by termites, etc)If you're asking about how to make it look less "dorm room" then you simply can buy some furring strips (1x1, or 1x2) attach them to the C.Block with liquid nails or actual nails, and then go 1/2in drywall on the furring strips.

Tends to be different thicknesses everywhere and you'll need furring strips... not worth it. 

This can be accomplished by filling empty block cells with blown insulation and/or furring out the inside faces of the walls and adding batts.

Is it furred out?

(I can still see Mom out there in her long wool coat, those ridiculous zip-up rubber boots with the fake fur on them...and oh yes, the scarf tied on her head...shoveling as hard as any man every could!!)

The walls, fans, and air conditioning units were covered in fur and there is a greasiness all over the cabinets with fur imbedded in it.

An alternative would be to attach furring strips and hang regular drywall over the wall then finish it as needed.

Now, they have two small dogs that shed a lot of fur and they chose to live in a house where 90% of it is carpeted.How would you handle them going forward, besides going over there more often than 6 months?

My houses use concrete block walls with furring strips nailed to then that then have the drywall applied on top of that.
