Carpet Weight Density Factor

Depending on other features of your carpet a lower or higher face weight may be required.

Carpet weight density factor.

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. 36 density x face weight pile height e g 36 2160 x 30 0 499998 0 5 in this example what we know is that the. 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. For example a 1 8 gauge carpet has eight tuft rows per inch of width and a 5 32 gauge carpet has 6 4 rows per inch of.

You want at least a 35 ounce face weight carpet for maximum durability. In other words if you measure the carpet face weight which is given in ounces multiply it by 36 and divide it by the pile height the height of the carpet fiber measured in fractions of an inch you ll get the density which is given in oz cubic yard. Guidelines for face weight. Simply put carpet density numbers refer to how close together the fibers of your carpet are tufted into the backing.

Density factor the density factor is the relationship between surface pile weight above the backing and pile thickness. A carpet density rating is one of the factors that determine how well your carpeting will perform. We can now use rule 2 to determine the face weight in ounces. Carpet rule 2.

Carpet rule 3. It measures surface weight of yarn per cubic centimetre as this provides a much better method of comparing one carpet to another taking into account different pile thickness. In tufted carpet gauge or the reciprocal of the number of tuft rows per inch of width is a major density factor. Density is often misconceived as a carpet s face weight but these two terms are completely different.

Here is the formula. Fiber face weight x 36 divided by pile height in decimal form pile density. If you buy a carpet with a face weight of 60 ounces and a 1 2 inch pile height you ll multiply 60 x 36 to obtain 2160 and then multiply that by 1 2 or 5 to obtain a carpet density of 1080 ounces in each cubic yard. According to the carpet and rug institute inc extra heavy traffic conditions such as are found in heavy commercial use require a minimum density of 5 000.
