Homeowners unable to efficiently retrofit insulation in finished attics without major reconstruction

Homeowners with finished attics discover poor or partial insulation after construction is complete, facing a painful choice between living with energy inefficiency, high heating/cooling costs, or expensive deconstruction and reinstallation. Current solutions require either tearing down finished walls/ceilings or accepting permanent thermal problems, making the fix prohibitively expensive or impractical for most DIYers and contractors.
