Why do you need to know the ‘Rt’ Rating of the ducts you choose?
Answer: Because the better the ‘Rt’ Rating, the cooler your air will be. And this goes to how much extra work your air-conditioner will do if the ducting is underperforming. It also affects how much extra electricity you have to pay if your ducting’s ‘Rt’ Rating is inadequate.

So the reason to compare the effectiveness of ducting insulation is to determine how well different ducting keeps the air cool that passes through it. And the same applies in the winter, for hot air, when using the air-conditioner for heating.
