WHAT IS CARPET BACK?
Most carpets are tufted or punched through one backing with a series of needles. The backing that you see is the secondary backing used to “sandwich” the fiber between the primary and secondary backing using a latex glue. The tightness of the weave of this secondary backing is not as important as the latex glue holding the backings together. If the latex fails, the two backings de-laminate and the fiber starts to fall out; also the carpet , if installed wall- to- wall, will wrinkle. This is a mill defect that cannot be seen until a time beyond that of most warranties. Most often the more expensive carpets use a better quality latex, thus insuring a long lasting installation.

Life cycle assessment confirms that Graphlex has a lower environmental impact than current available backing alternatives. But we want to do more. We are continuously looking for alternatives for our backing, including new sources of postconsumer recycled content and bio-based materials.
FACTS ON BACKINGS
All carpet has some type of backing system or chemistry that helps keep the tufts in place. Backing systems are made from a variety of materials and may also come with various kinds of protective treatments (such as anti-microbial or anti-stain) or beneficial properties (such as anti-static).
The methods and chemicals used depend upon the performance requirements of the backing and the carpet. These decisions will be based upon the specifier’s performance considerations and the manufacturer’s recommendations. Performance considerations are especially important for demanding environments. It’s important that the specifier identify the highest priority needs for how the carpet will perform, whether that is wear and tear, moisture-resistance, or heavy foot traffic. The manufacturers’ end use recommendations help determine which product will meet the established performance expectations.
