Every insulation has a different R value. It ultimately is determined by which insulation you will be using. Now lets do rough estimate. 4" thick, regular fiberglass mat has R-value of 13. Assuming that plywood has the same to half the insulating value of fiberglass, 1/2" plywood would have 1/8 to 1/16 of R-value of that 4" mat. Roughly R-1.6 to R-0.8

Does r-5 insulation hold more heat than r-35 insulation?
No, R-5 insulation does not hold more heat than R-35 insulation. The R-value measures an insulation material's resistance to heat flow; a higher R-value indicates better insulation performance. Therefore, R-35 insulation is significantly more effective at reducing heat transfer compared to R-5 insulation, making it a better choice for retaining heat in a space.
