How important is face weight.
Carpet face weight and density.
An olefin sample may weigh more than a nylon but it has entirely different performance qualities.
Factors that may affect the minimum face weight needed are how often the room is used the carpet s twist level and the carpet s density.
As an example within one product line the good level carpet has a face weight of 40 oz.
Face weight and density are two entirely different components when it comes to evaluating the quality of a carpet.
Carpet face weight refers to the weight of the fiber found in 1 square yard of carpet.
Fiber face weight x 36 divided by pile height in decimal form pile density.
For example a 35 ounce face weight carpet with a half inch pile height would have a pile density rating of 2520 35 x 36 divided by 5 2520.
Depending on other features of your carpet a lower or higher face weight may be required.
The standard is measured in ounces.
Carpet density refers to how close together the fibers are tufted into the carpet backing.
The units will be expressed in ounces per cubic yard.
You want at least a 35 ounce face weight carpet for maximum durability.
The best level weighs in at 63 oz.
Fiber face weight is not the same as total carpet weight which includes the weight of the carpet backing and the fiber face weight.
Does face weight matter.
Here is the formula.
The term refers to the weight of the carpet s fibers only not the backing material.
Be wary of dealers who try to sell you on carpet density or stitches per inch spi.
Most carpets have a face weight between 20 ounces and 100 ounces but the average face weight for a residential carpet is about 45 ounces.
It should not be confused with the carpet s total weight which is the combined weight of the pile plus the backing.
