What Is A Good R Value For Carpet

Having explained the science how can this information help make sound floor covering decisions in terms of energy efficiency.

What is a good r value for carpet.

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. The insulating value of the padding must also be combined with the r value of the installed carpeting.

Although carpet is not. These r values are a sum meaning this should be the total r value once you add up the entire depth of insulation. 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. Both the carpet and the underlay will have a separate tog rating and a combined rating over 2 0 isn t really suitable for underfloor heating.

Some carpet and padding combinations can measure an r value of over. 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. 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. As we said before the r value measures the thermal resistance of a material. For example wool carpet rates a maximum r value of 2 1 while other types of carpet can rate as low as 0 7. R value is the thermal resistance rating of a carpet.

While r value is an important factor to consider when choosing a flooring material you must also consider your aesthetic preferences. Adding these two together will produce a r value that can exceed 2 0. 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. A low rating is perfect for use with under floor heating while a high rating means the carpet and underlay already offer good insulation and therefore isn t suitable for under floor heating.
