Inquiry

Carpet tile is not currently considered an acceptable entryway system. One reason carpet tile is not accepted is because it cannot be cleaned underneath and therefore does not meet the performance of mechanical systems (such as grates/grilles), or roll-out mats. Carpet tile is a highly desired material for walk off areas due to its ease of maintenance as compared to mechanical systems, avoidance of trip hazards associated with roll-out mats, and numerous other factors. The ability to clean underneath carpet tile is not necessary. Carpet tile creates a sealed floor where dirt and moisture do not penetrate the seams. Though not specifically required by the rating system, the reference guide provides suggestions for optimal performance attributes for entryway systems. The carpet tile product we are suggesting meets the performance-related attributes as follows: Capture particles & prevent interior contamination- the carpet tile product is specifically designed to withstand heavy traffic at entranceways. Captures and hides soil, requires minimal maintenance and helps prevent slips and falls. Extend 10 feet: the carpet tile will extend 15' into the interior from the exterior entrance and 40' in left-right directions along the building lobby. Solid backings & appropriate for climate- the carpet tile backing is stable even under extreme changes in temperature and humidity. It will not move, create gaps, or curl up over time. High-void-volume & high fiber height- the carpet tile is produced with needlepunch hair-like face fibers with pile height of 0.165 in. Electrostatic propensity- the electrostatic propensity level is less than 2.5 kV. Weekly cleaning - the walk-off system will be maintained by the in-house school maintenance staff. The tiles are vacuumed daily and spot cleaned with appropriate environmentally-preferable cleaning products as needed. If an individual tile is deemed to be damaged beyond repair, it is simply removed and immediately replaced with a new identical tile. How can we demonstrate that carpet tile is an equally performing or better solution for entryway systems?
