R value is calculated by dividing the material s thickness by its k value.
Carpet pad r factor.
The r factor is how well the padding will prevent heat from moving from one place to another.
It is measured by pounds per cubic foot and those in the 6 pound and 8 pound range provide comfort and durability for residential uses.
Because of this thickness dependency r values can only be compared at the same material thickness.
For example wool carpet rates a maximum r value of 2 1 while other types of carpet can rate as low as 0 7.
Urethane padding has the highest r value of all padding choices.
The density of the carpet pad foam is another factor to consider.
These numbers will vary from material to material.
R values of different flooring materials.
R values of different flooring materials.
Adding these two together will produce a r value that can exceed 2 0.
Carpet pads with a higher r factor will trap heat more successfully preventing the flow of warmth through the material so that all your heat doesn t seep out through your floors.

Carpet pad and the r factor.
The carpet padding also effects room temperature and some may say that the padding under the carpet does just as much or more insulating than the actual carpet itself.
The insulating value of the padding must also be combined with the r value of the installed carpeting.
An r factor in carpeting is a measurement of the carpet padding s resistance to heat flow.
The r value rating is anywhere from 1 05 to 2 15 dependent upon the thickness of the pad.
While r value is an important factor to consider when choosing a flooring material you must also consider your aesthetic preferences.
Although carpet is not.
The second important metric to keep in mind is the r factor which refers to a carpet pad s ability to resist the flow of heat.
