Carpet Tile Density

Pile density is the key to having a carpet retain its like new appearance longer.

Carpet tile density.

Many people say that a carpet density at 3000 or higher is ideal for normal household conditions but you can discuss those details with your design consultant. To calculate carpet density it s a simple calculation of carpet face weight x 36 carpet pile height. But remember that there are other factors that impact durability. Don t confuse density and twist with face weight which is the amount of fiber measured in ounces per square yard as opposed to total weight which includes the weight of the carpet backing.

Carpet doesn t have to be dense to be durable as long as it has a high twist level and vice versa. When buying a carpet to use in typical home environments you ll want to see a density value of at least 3 600. It should not be confused with the carpet s total weight which is the combined weight of the pile plus the backing. It s not a necessity to go through all this math when you have a local carpet company that does it for you.

We can now use rule 2 to determine the face weight in ounces. The carpet and rug institute cri recommends a density of 5 000 or higher for extra heavy traffic conditions. Density is the best specification to determine durability. Here s a simple example.

The term refers to the weight of the carpet s fibers only not the backing material. You want a carpet density with a density of 2 900 for good durability and i d be cautious with anything less than 2 500 in moderate traffic rooms. Skip the mathematics and make carpet easy. Carpet face weight is defined as the weight of the carpet pile per square yard of carpet measured in ounces.

Pile density ratings range from 1000 to 6000 and is determined using a mathematical formula based on the pile height and the fiber face weight. Face weight won t tell you a lot about the durability of a carpet without knowing the density and twist as well. Of course more is better as the higher the value the longer your carpet is likely to last in a home before it begins to noticeably break down. 36 density x face weight pile height.

Carpet rule 3. In general the higher the carpet density numbers the better your carpet will perform under pressure. Carpet rule 2. Density x pile height 36 face weight e g 2160 x 0 50 36 30 in this example what we know is that the pile density is 2160 and the pile height is 0 5 one half inch.

The more densely the tufts are packed together the more durable the carpet will be.
