Some carpet and padding combinations can measure an r value of over.
Carpet padding with 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.
In most cases floor covering will be used in the insulation mode.
Being in the middle with its r value fiber padding provides a pretty good warming and cooling property along with decent carpet support.
While r value is an important factor to consider when choosing a flooring material you must also consider your aesthetic preferences.
For example wool carpet rates a maximum r value of 2 1 while other types of carpet can rate as low as 0 7.
For radiant floor heating you want the total r value to be as low as possible lower than 4 0.
The insulating value of the padding must also be combined with the r value of the installed carpeting.
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.
Adding these two together will produce a r value that can exceed 2 0.
In this case choose cushion and carpet.
For some homeowner s the sleek look of tile is more important than heat.
