Other benefits of concrete blocks include.
Concrete blocks can also be used to quickly erect partition walls with steel reinforcing rods used to fill the voids and make walls stronger.
The option for insulating concrete block walls includes spray foam insulation injection foam insulation polystyrene beads foam boards and loose fill masonry insulation.
The hollow cores of concrete blocks can be filled by pouring and or injecting loose foam beads or liquid foam.
In addition builders can easily and quickly construct an icf wall compared to complicated and time consuming concrete block construction.
Depending on whether the concrete block walls will be covered or if the top of the wall is exposed can really change the way they are insulated.

Adding layers of closed cell foam polyurethane sheeting or reflective barriers to a concrete wall can all increase the insulation value of concrete.
Would rigid insulation on the exterior and veneer or lathe and stucco do the trick.
However unlike icf walls concrete blocks provide little thermal resistance so to achieve sufficient energy efficiency the walls require an application of insulation.
Your walls in their present state have an r rating of about 3.
Because solid walls have no gap heat bridges through the material to the outside.
As for the furring used for interior insulation the thermal resistance of the concrete masonry webs and any grouted cores should be accounted for when determining the thermal performance of the wall see tek 6 2c ref.
When using core insulation the insulation should occupy all ungrouted core spaces although some rigid inserts are configured to accommodate reinforcing steel and grout in the same cell.
