Which Has More R Value Carpet Or Carpet Pad

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.

Which has more r value carpet or carpet pad.

Urethane padding has the highest r value of all padding choices. The r value is based less on what the carpet is made of than on the actual thickness of the carpet. If you choose a low pile carpet which includes berber loop pattern carpet and commercial varieties the carpet pad thickness should be 3 8 inch or less. In most cases floor covering will be used in the insulation mode.

Padding has higher r value which measures a material s ability to keep heat from passing through it than carpet keeping the room warmer. In fact the choice of carpet padding also effects the room s temperature with its varying r value. With over 40 years of manufacturing experience healthier choice is committed to producing the most durable and resilient underlay for carpet laminate and wood floors. Healthier choice is a leading manufacturer of premium carpet cushion and acoustical underlayment for the flooring industry.

A cushion with an r value of 2 and a carpet with an r value of 1 would have an r value of 3 for the composite. R value is the thermal resistance rating of a carpet. The r value rating is anywhere from 1 05 to 2 15 dependent upon the thickness of the pad. The density of the carpet pad foam is another factor to consider.

In contrast a carpet with a carpet pad under it resulted in a loss of 5 10 during the test. R values for carpet typically range from around 2r to 2r but can vary somewhat. In this case choose cushion and carpet combinations with the highest r values. Remember certain types of cushion provide superior insulation but also thicker cushion will give a higher r.

Having explained the science how can this information help make sound floor covering decisions in terms of energy efficiency. The r values of the carpet and padding add together for a total r value. 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. According to the independent textile testing service carpet without a carpet pad under it resulted in a 19 3 loss in thickness after a 150 lb.

Cut pile residential carpet such as those with textures and twists should have padding with a thickness of 1 2 inch or less. 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. Just multiply the carpet s thickness in inches including the carpet pad by 2 6 source. A higher r value insulates better than a lower value since this value reflects the material s.
