MINIMUM RECOMMENDED CRITERIA FOR SATISFACTORY CARPET CUSHION PERFORMANCE IN CONTRACT INSTALLATIONS

To help you compare various types of cushion, the Carpet Cushion Council has established recommended minimum contract cushion criteria for three levels of traffic. Any cushion type and grade certified as meeting CCC's guidelines for cushion being installed at a particular traffic level can be expected to perform satisfactorily at that level under normal conditions, when used with a carpet made for the same specified traffic. Red Label: Commercial - Moderate Traffic; Green Label: Commercial - Heavy Traffic; Blue Label: Commercial - Extra Heavy Traffic.

TYPES OF CUSHION CLASS I - MODERATE TRAFFIC CLASS II - HEAVY TRAFFIC CLASS III - EXTRA HEAVY TRAFFIC
