Yes, you can install additional insulation underneath the existing R12 insulation in your basement and then put framing on top. Ensure the new insulation has a compatible R-value with the existing one. Consider adding a vapor barrier on the warm side of the new insulation, and make sure the framing allows for proper ventilation. Before proceeding, you should ensure compliance with building codes and regulations. This approach can enhance energy efficiency and create a more comfortable living space in your basement.

Yes you can, just have to match up and insulation R value and poly the outside and your good to go. Just remember an insulated home is a warm home. And seeing as there is no leaks meaning the outside of the basement has been done correctly than you may go ahead with drywall and get the job to the next step.

Done wrong...builders do that pinned insulation direct too walls as a cheapo method to clear final permit. If you want a professional job, it has to have a air gap of 1/2" from concrete to prevent condensation build up and future mold. If you want to do it right, rip it all out, frame frost walls 1/2" min from foundation walls then put in batt insulation (Roxul/Rockwool is best) and vapor barrier on warm side, you also need to fully insulate and vapor barrier the joist pockets
