Thinking of wrapping a round 8 foot dia. metal wall tank with 1/2 inch foil faced polyiso rigid board to 4 inch thickness. Probably have to score outside face to get curvature on the tank. Question is will R value go up or down with this configuration?

I use 2 layers of Reflectix bubble wrap with the aluminum tape on the seams. Available in 4 or 5 ft widths x 50ft roll.Comment
