Carpet with low r value.

Best carpet for resale value. 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. Some carpet and padding combinations can measure an r value of over.

A great choice for a carpet pad would be 1 4 inch slab rubber foam. Thicker pile or berber style. If veiwing this page on a phone it s best to turn the phone to view in landscape mode r values of flooring materials. You don t want to insulate right above your radiant heat source otherwise your radiant heat system will have to expend more energy to heat the room.

R values of different flooring materials. R values of different flooring materials. This is a thin and dense material with a very low r value. The key here is high density and a low r value.

The r values of the carpet and padding add together for a total r value. In this case choose cushion and carpet. These r values are a sum meaning this should be the total r value once you add up the entire depth of insulation. Having explained the science how can this information help make sound floor covering decisions in terms of energy efficiency.

Notes to the table above. For example wool carpet rates a maximum r value of 2 1 while other types of carpet can rate as low as 0 7. Being in the middle with its r value fiber padding provides a pretty good warming and cooling property along with decent carpet support. Rosato asbestos insulation is the most authoritative source on asbestos properties and gives data for the thermal conductivity of asbestos in different forms and with varying temperatures for magnesia asbestos insulation at mean temperatures ranging from 100 f to 400 f the k value thermal.

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. When you add both the r value of the carpet and the pad together you will get the complete r value and insulation value added to your home. 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. These numbers will vary from material to material.

As an alternative you can buy synthetic products that have a green label plus from the carpet and rug institute.
