Is r-value good or bad?
it is a good thing i think R Value is the thermal resistance of a given material. The higher the R Value the more thermal resistance and the better the insulation. So, an R48 roof system is warmer than an R32 roof system. All insulation materials are rated by their R Value. An inch of rigid insulation has a higher R Value than an inch of fiberglass insulation. Check with the insulation manufacturer for the R Value.
What is the recommended R value for roof insulation?
R 13 for 3.5" wall cavities, R19 for 5.5". R30 for blown in insulation and batts in ceilings.
What is the proper r-value for insulation for ceilings and exterior walls?
The required R value for walls and roof insulation varies depending on your local building authority. The ideal R value will depend on the climate, altitude, latitude and exposure of your site and the form, amount of glazing,materials and use of the building.

U value of r-19 insulation?
The U value is the inverse of the R value. For R value 19 insulation the U value is 1/19, or 0.0526.
