Cathedral ceiling with tongue and groove ceiling. Looking for solutions.

Did audit last week and homeowner is always cold in these two rooms with cathedral ceilings and large exposed beams. Thinking of installing Thermax in between each cavity and then adding drywall. Any thoughts. Customer is willing to go this way but wondering if there are other solutions.See More
