How to Select Commercial Carpet for your Business
A perfectly selected commercial carpet. It's durable. The color is practical. And the waiting room looks great.There are five main concerns you should have when choosing a commercial carpet for your business.
- Is the carpet Suitable for the area?
- Is the carpet Durable?
- Is the carpet Easy to Maintain?
- Is the carpet Attractive?
The following can get technical, but is well worth it if you want to get the most from your investment in commercial carpeting.
SuitabilityIs the carpet suitable for the area?
Fire RatingsCarpet is rarely the source of fire. However, it can be involved once a fully involved fire has started in an area. Here is the simplified version of the two fire ratings you need to know about.
The first is the NBS Smoke Chamber Test. Smoke is often the most lethal part of a fire, so having materials in your business that reduce smoke in the event of a fully involved fire is important. All carpets must have an NBS Smoke Chamber Test of 450 or less, or it can not be legally manufactured in the United States. This includes all commercial and residential carpet. If the carpet is for sale, it needs to pass this test.
The second fire rating is the ASTM E-648 Radiant Panel test. For commercial carpet, the results of this will be either Class I or Class II. Typically, Class I should be used in corridors, entrances, and exits of health care facilities (hospitals, nursing homes, etc) as well as new construction (not existing) correctional or detention facilities. Class II can be used everywhere else, including exits, entrances, corridors of hotels, retail space, day care centers, schools and apartment buildings. Note that local building codes can supercede these requirements.
Special ConsiderationsHave a professional help you with special considerations. These include but are not limited to:
- Wet areas.
- Areas that could be exposed to chemicals (i.e., chlorine dripping from bathing suits).
- Super high traffic.
- Rolling traffic.
- Light vehicles.
DurabilityBusinesses get much more traffic than domestic areas like homes and apartments. When you are carpeting a business, you need durable. There is a special class of carpet called commercial carpet that is designed specifically for the extreme traffic that businesses get.
There are three factors you need to address to be sure your carpet will be durable.
- Pattern and/or Heathering
Typical specifications for commercial carpet.You can get specifications for the commercial carpet you are considering. Many stores and manufacturers will tell you face weight. Face weight is indicated in ounces of yarn per square yard. Typical numbers for commercial carpet can range from 16 ounces per square yard to 40 ounces per square yard. Face weight may also be called pile weight.
Face weight is NOT density. It is imperative to understand this to be sure you are selecting a suitable carpet for your business. Why? Because we can take an amount of yarn and make it short but tight together, or we can take the same amount of yarn and make tall, but loose and fluffy. The short, tight pile will be much more durable even though it has the same face weight as the other carpet.
The photo to the right shows a typical product specification for a popular commercial carpet. It tells us that the pile weight is 24 oz. per square yard. But we now know that is not what we want. So we keep looking and find another figure called "Density" listed at 5,236 oz. per cubic yard. You will note another number listed as weight density, but that is not what we want. The number you want should have a range somewhere between 2,000 and 10,000. For commercial carpet, the range starts around 4,000.
What if I can't find pile density? Pile density can also be calculated if you know pile weight and pile thickness. Density = pile weight X 36 / pile thickness. Pile weight will be in ounces per square yard. Pile thickness will be in inches. For instance, using the photo to the right, we calculate density as Density = 24 * 36 / 0.165 = 5236.
Now that we have the cubic volume density of the carpet pile, what do we do with it? Here is a guideline for pile density.
- 4,000 and higher. Moderate Traffic.
- 5,000 and higher. Heavy Traffic.
- 6,000 and higher. Extra heavy traffic.
- 7,000 and higher. Super heavy traffic.
Caution: We are rating commercial carpet. Do not make the mistake of using this to rate carpet for your home. Commercial carpet will be low and hard. That is NOT what you want for your home.This chart is a guideline only. Some situations are special cases for which you should seek professional advice. An airport corridor, for instance, has stupendously high traffic, rolled luggage, dragged luggage, wheelchairs, and light duty vehicles. This is a very special situation that no chart will ever encompass.
So what does that "heavy traffic" rating mean? It means that the pile will not mat or crush down excessively over the intended lifetime of the carpet in heavy traffic situations. (The pile will crush down, but not excessively. And we expect the pile to gradually crush or mat over the life of the carpet. This would be as opposed to an improperly selected carpet that would mat down very quickly.)
Heathered colors in commercial carpet are much more practical than solid colors.Not matting is only one part of selecting a durable commercial carpet. You also need to select a sensible color. If you select a carpet rated for Super heavy traffic, but the color is white, we are headed for disaster. Very light colors will show soiling. On the other hand, very dark colors may be great at hiding soiling, but may show lint. Medium to darker-medium colors work best for most businesses.
Please note the color of the soil in your area. If your business is located on the beach and people are dragging in light colored sand, then a lighter color may make more sense for you.
For our main service area, we have dark loamy soil. This soil imparts a yellow-ish hue when combined with most carpet colors. Use the following chart in this case.
|Practical Colors||Impractical Colors|
|Green (not teal)||Blue|
|Brown, Tan||White, Cream, Ivory|
