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.
