R values of different flooring materials.
Carpet with low r value.
While r value is an important factor to consider when choosing a flooring material you must also consider your aesthetic preferences.
Notes to the table above.
Thicker pile or berber style.
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.
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.
The r values of the carpet and padding add together for a total r value.
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.
Best carpet for resale value.
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.
As an alternative you can buy synthetic products that have a green label plus from the carpet and rug institute.
In this case choose cushion and carpet.
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.
These r values are a sum meaning this should be the total r value once you add up the entire depth of insulation.
This is a thin and dense material with a very low r value.
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.
Being in the middle with its r value fiber padding provides a pretty good warming and cooling property along with decent carpet support.
Notes on the r value k values of different forms of asbestos.
R values of different flooring materials.
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.
The key here is high density and a low r value.
Carpets made with natural fibers such as wool or cotton usually have the lowest amounts of volatile organic compounds vocs.
A great choice for a carpet pad would be 1 4 inch slab rubber foam.
Some carpet and padding combinations can measure an r value of over.
