Carpet R Value

From 8 to 17 times the r value carpet with cushion represents a clear advantage in insulation capability over hard surface flooring.

Carpet r value.

These numbers will vary from material to material. For example if you have a type of insulation that has an r value of r 5 per inch of thickness you will need a depth of 6 inches of this insulation installed in your attic to reach r 30 if you live in zones 2 or 3. R value is calculated not from the actual materials as much as from the thickness of the carpet. Often you can find the r value on the label when you are shopping for a new carpet but if it s not on the label you can figure out the carpet s approximate r value on your own.

R value is the thermal resistance rating of a carpet. From 4 to 8 times the r value carpet vs. Material thermal insulation r value m2k w concrete 10 cm thick 0 07 0 08 carpet 1 cm thick 0 18 fibreglass insulation 1 cm thick 0 22 thermal resistance of materials1 the r value is used to measure a material s resistance to heat transfer or thermal resistance the higher the r value the greater the insulating effect. For radiant floor heating you want the total r value to be as low as possible lower than 4 0.

Of course potential energy cost savings by using carpet and cushion in lieu of hard surfaces will vary widely. If veiwing this page on a phone it s best to turn the phone to view in landscape mode r values of flooring materials. The insulating value of the padding must also be combined with the r value of the installed carpeting. Having explained the science how can this information help make sound floor covering decisions in terms of energy efficiency.

In most cases floor covering will be used in the insulation mode. The r value is based less on what the carpet is made of than on the actual thickness of the carpet. R values of different flooring materials. Adding these two together will produce a r value that can exceed 2 0.

Although carpet is not. While r value is an important factor to consider when choosing a flooring material you must also consider your aesthetic preferences. In this case choose cushion and carpet. R values of different flooring materials.

The r values of the carpet and padding add together for a total r value. These r values are a sum meaning this should be the total r value once you add up the entire depth of insulation. If the r value for your carpet is not labeled or readily available it can be easily calculated by multiplying the carpet s thickness in inches but 2 6.
